Although I not very familiar with ACPI, to me it looks like struct acpi_dmar_header::length == 0x0058 is incorrect, causing parse_dmar_table() to look at an invalid offset on the next loop. This offset happens to have struct acpi_dmar_header::length == 0x0000, which prevents the loop from ever terminating. This patch checks for this condition and bails out instead of looping forever.

The GCD monopolizes the scheduler (which in turns means it gets to do more nand i/o), which results in processes taking much much longer than they should to start. As an example, on an OLPC machine going from OFW to a usable X (via auto-login gdm) takes 2m 30s. The majority of this time is consumed by the switch into graphical mode. With this patch, we cut a full 60s off of bootup time. After bootup, things are much snappier as well. Note that we have seen a CRC node error with this patch that causes the machine to fail to boot, but we've also seen that problem without this patch.

Instead of checking the global bytes counter we check the space_info bytes counters to make sure we have enough space. If we don't we go ahead and try to allocate a new chunk, and then if that fails we return -ENOSPC. This patch adds two counters to btrfs_space_info, bytes_delalloc and bytes_may_use. bytes_delalloc account for extents we've actually setup for delalloc and will be allocated at some point down the line. bytes_may_use is to keep track of how many bytes we may use for delalloc at some point. When we actually set the extent_bit for the delalloc bytes we subtract the reserved bytes from the bytes_may_use counter. This keeps us from not actually being able to allocate space for any delalloc bytes.

Instead of returning -ENOSPC immediately, commit the transaction first and then try and do the allocation again. This patch also does chunk allocation for metadata if we pass the 80% threshold for metadata space. This will help with stack usage since the chunk allocation will happen early on, instead of when the allocation is happening.

When the ultimate node is removed at scan time and the overlapped flag is set on the penultimate node, then nothing updates the overlapped flag of that node. The overlapped iterators blindly expect that the ultimate node does not have the overlapped flag set, which causes the scan code to crash. It would be a huge overhead to go through the node chain on node removal and fix up the overlapped flags, so detecting such a case on the fly in the overlapped iterators is a simpler and reliable solution.

One of its problems (besides ignoring the Orlov algorithm) is that it is a bit hyperactive about returning failure under suspicious circumstances. This can lead to spurious ENOSPC failures even when there are inodes still available. Work around this for now by retrying the search using find_group_other() if find_group_flex() returns -1. If find_group_other() succeeds when find_group_flex() has failed, log a warning message. A better block/inode allocator that will fix this problem for real has been queued up for the next merge window.

The implementation is a bare minimum to get encrypted channels to work in kaffeine. It works fine with my T/CI card. Now and then I get an AVC timeout and have to retune a channel in order to get it to work. Once the CAM seemed to hang so I needed to remove and insert it again. I.e. there are a number of glitches. The latest version contains the following changes: - Implemented the new hpsb iso interface so that data can be received from the card - Reduced some timers for demux setup which caused scanning to timeout - Added possibility to unload driver - Added support for getting C/N ratio - Added two debug parameters to the driver; ca_debug and avc_comm_debug. - Added CI support that works for me in kaffeine - Started working on CI MMI support. It now supports: o Enter menu o Receiving MMI objects - Added support for 64-bit platforms - Corrected DVB-C modulations problems Signed-off-by: Henrik Kurelid Signed-off-by: Stefan Richter (rebased, whitespace) --- drivers/media/dvb/firesat/Makefile | 1 + drivers/media/dvb/firesat/avc_api.c | 768 ++++++++++++++++++----- drivers/media/dvb/firesat/avc_api.h | 296 +++++---- drivers/media/dvb/firesat/cmp.c | 40 +- drivers/media/dvb/firesat/firesat-ci.c | 346 ++++++++-- drivers/media/dvb/firesat/firesat.h | 174 ++++- drivers/media/dvb/firesat/firesat_1394.c | 123 +--- drivers/media/dvb/firesat/firesat_dvb.c | 49 +- drivers/media/dvb/firesat/firesat_fe.c | 80 ++- drivers/media/dvb/firesat/firesat_iso.c | 106 ++++ 10 files changed, 1488 insertions(+), 495 deletions(-) create mode 100644 drivers/media/dvb/firesat/firesat_iso.c diff --git a/drivers/media/dvb/firesat/Makefile b/drivers/media/dvb/firesat/Makefile index fdf86870f1fd..be7701b817c9 100644 --- a/drivers/media/dvb/firesat/Makefile +++ b/drivers/media/dvb/firesat/Makefile @@ -1,6 +1,7 @@ firesat-objs := firesat_1394.o \ firesat_dvb.o \ firesat_fe.o \ + firesat_iso.o \ avc_api.o \ cmp.o \ firesat-rc.o \ diff --git a/drivers/media/dvb/firesat/avc_api.c b/drivers/media/dvb/firesat/avc_api.c index cd79c806ecc7..273c7235dd90 100644 --- a/drivers/media/dvb/firesat/avc_api.c +++ b/drivers/media/dvb/firesat/avc_api.c @@ -3,6 +3,7 @@ * * Copyright (c) 2004 Andreas Monitzer * Copyright (c) 2008 Ben Backx + * Copyright (c) 2008 Henrik Kurelid * * This program is free software;

Per default, various media key keycodes are emitted which closely match what is printed on the remote. Userland can modify the mapping by means of evdev ioctls. (Not tested.) The old scancode-to-keycode mapping is left in the driver but cannot be modified by ioctls. This preserves status quo for old remotes. Tue, 26 Aug 2008 00:11:28 +0200 (CEST) firedtv: replace tasklet by workqueue job Non-atomic context is a lot nicer to work with. Sun, 24 Aug 2008 23:30:00 +0200 (CEST) firedtv: move some code back to ieee1394 core Partially reverts "ieee1394: remove unused code" of Linux 2.6.25. Sun, 24 Aug 2008 23:29:30 +0200 (CEST) firedtv: replace semaphore by mutex firesat->avc_sem and ->demux_sem have been used exactly like a mutex. The only exception is the schedule_remotecontrol tasklet which did a down_trylock in atomic context. This is not possible with mutex_trylock; however the whole remote control related code is non-functional anyway at the moment. This should be fixed eventually, probably by turning the tasklet into a worqueue job. Convert everything else from semaphore to mutex. Also rewrite a few of the affected functions to unlock the mutex at a single exit point, instead of in several branches. Sun, 24 Aug 2008 23:28:45 +0200 (CEST) firedtv: some header cleanups Unify #ifndef/#define/#endif guards against multiple inclusion. Drop extern keyword from function declarations. Remove #include's into header files where struct declarations suffice. Remove unused ohci1394 interface and related unused ieee1394 interfaces. Add a few missing #include's and remove a few apparently obsolete ones. Sort them alphabetically. Sun, 24 Aug 2008 23:27:45 +0200 (CEST) firedtv: nicer registration message and some initialization fixes Print the correct name in dvb_register_adapter(). While we are at it, replace two switch cascades by one for loop, remove a superfluous member of struct firesat and of two unused arguments of AVCIdentifySubunit(), and fix bogus kfree's in firesat_dvbdev_init(). Tue, 26 Aug 2008 14:24:17 +0200 (CEST) firesat: rename to firedtv Suggested by Andreas Monitzer. Besides DVB-S/-S2 receivers, the driver also supports DVB-C and DVB-T receivers, hence the previous project name is too narrow now. Not yet done: Rename source directory, files, types, variables... Sun, 24 Aug 2008 23:26:23 +0200 (CEST) firesat: add missing copyright notes Reported by Andreas Monitzer and Christian Dolzer.

Use hardware memory barriers on systems which need them. (Of course a full fix of generation handling would require much more than this. The ieee1394 core's bus generation counter had to be tied to the controller's bus generation counter; cf. Kristian's stack. It's just that I have other current business with the code around these barrier()s, so why not do at least this small fix.)

We now always copy ne->vendor_id into ud->vendor_id before we scan a unit directory (and fill in a possibly present vendor ID from there). This way, the root directory's vendor ID is used as fallback in the "uevent" environment for modprobe'ing per module alias when a node was plugged in, and in the driver match routine when protocol drivers are bound to unit directories. It will however not be used as sysfs attribute of a unit directory device.

Effect of the fix not yet tested. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: replace mdelay by msleep These functions can sleep (and in fact sleep for the duration of a whole FCP transaction). Hence msleep is more appropriate here. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial reorganization in avc_api Reduce nesting level by factoring code out of avc_tuner_dsd() into helper functions. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in avc_api Use dev_err(), no CamelCase function names, adjust comment style, put #if 0 around unused code and add FIXME comments, standardize on lower-case hexadecimal constants, use ALIGN() for some frame length calculations, make a local function static... The code which writes FCP command frames and reads FCP response frames is not yet brought into canonical kernel coding style because this involves changes of typedefs (on-the-wire bitfields). Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: don't retry oPCR updates endlessly In the theoretical case that the target node wasn't handling the lock transactions as expected or there was continued interference by other initiating nodes, these functions wouldn't return for ages. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove bitfield typedefs from cmp, fix for big endian CPUs Use macros/ inline functions/ standard byte order accessors to read and write oPCR register values (big endian bitfields, on-the-wire data). The new code may not be the ultimate optimum, but it doesn't occur in a hot path. This fixes the CMP code for big endian CPUs. So far I tested it only on a little endian CPU though. For now, include instead of because drivers/ieee1394/*.h also include the former. I will fix this in drivers/ieee1394 and firedtv later. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in cmp Reduce nesting level by means of early exit and goto. Remove obsolete includes, use dev_err(), no CamelCase function names... Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: trivial cleanups in firesat-ci Whitespace, variable names, comment style... Also, use dvb_generic_open() and dvb_generic_release() directly as our hooks in struct file_operations because firedtv's wrappers merely called these generic functions. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove CA debug code This looks like it is not necessary to have available for endusers who cannot patch kernels for bug reporting and tests of fixes. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove AV/C debug code This looks like it is not necessary to have available for endusers who cannot patch kernels for bug reporting and tests of fixes. Sun, 2 Nov 2008 13:45:00 +0100 (CET) firedtv: remove various debug code Most of this was already commented out. And that which wasn't is not relevant in normal use. Mon, 29 Sep 2008 19:22:48 +0200 (CEST) firedtv: register input device as child of a FireWire device Instead of one virtual input device which exists for the whole lifetime of the driver and receives events from all connected FireDTVs, register one input device for each firedtv device. These input devices will show up as children of the respective firedtv devices in the sysfs hierarchy. However, the implementation falls short because of a bug in userspace: Udev's path_id script gets stuck with 100% CPU utilization, maybe because of an assumption about the maximum ieee1394 device hierarchy depth. To avoid this bug, we use the fw-host device instead of the proper unit_directory device as parent of the input device. There is hope that the port to the new firewire stack won't be inhibited by this userspace bug because there are no fw-host devices there. Mon, 29 Sep 2008 19:21:52 +0200 (CEST) firedtv: fix string comparison and a few sparse warnings Sparse found a bug: while ((kv_buf + kv_len - 1) == '\0') should have been while (kv_buf[kv_len - 1] == '\0') We fix it by a better implementation without a temporary copy. Also fix sparse warnings of 0 instead of NULL and signedness mismatches. Mon, 29 Sep 2008 19:21:20 +0200 (CEST) firedtv: remove unused struct members and redefine an int as a bool. Mon, 29 Sep 2008 19:20:36 +0200 (CEST) firedtv: fix initialization of dvb_frontend.ops There was a NULL pointer reference if no dvb_frontend_info was found. Also, don't directly assign struct typed values to struct typed variables. Instead write out assignments to individual strcut members. This reduces module size by about 1 kB. Mon, 29 Sep 2008 19:19:41 +0200 (CEST) firedtv: remove unused dual subunit code from initialization No FireDTVs with more than one subunit exists, hence simplify the initialization for the special case of one subunit. The driver was able to check for more than one subunit but was broken for more than two subunits. While we are at it, add several missing cleanups after failure, and include a few dynamically allocated structures diretly into struct firesat instead of allocating them separately. Mon, 29 Sep 2008 19:19:08 +0200 (CEST) firedtv: add vendor_id and version to driver match table Now that nodemgr was enhanced to match against the root directory's vendor ID if there isn't one in the unit directory, use this to prevent firedtv to be bound to wrong devices by accident. Also add the AV/C software version ID to the match flags for completeness; specifier ID and software only make sense as a pair. Mon, 29 Sep 2008 19:18:30 +0200 (CEST) firedtv: use hpsb_node_read(), _write(), _lock() because they are simpler and treat the node generation more correctly. While we are at it, clean up and simplify surrounding code.

So bring it back in an updated form with only 60% of the original code footprint. Logging can be enabled with # echo -1 > /sys/module/firedtv/parameters/debug 1 instead of -1 enables only FCP header logging, 2 instead of -1 enables only hexdumps of the entire FCP frames. 0 switches logging off again. Fri, 20 Feb 2009 20:54:27 +0100 (CET) firedtv: build fix for INPUT=m and DVB_FIREDTV=y Thu, 19 Feb 2009 20:40:39 +0100 firedtv: use msecs_to_jiffies Pointed out by Mauro Carvalho Chehab. Sun Feb 15 20:50:46 CET 2009 firedtv: some more housekeeping Fix an old checkpatch warning and a new compiler warning. Sun Feb 15 15:33:17 CET 2009 firedtv: rename a file once more At the moment, about a third of avc.c is specific to FireDTVs rather than generic AV/C code. Rename it to firedtv-avc.c. Sun Feb 15 15:33:17 CET 2009 firedtv: dvb demux: more compact channels backing store Replace struct firedtv_channel { bool active; int pid; } channel[16]; by unsigned long channel_active; u16 channel_pid[16];. Sun Feb 15 15:33:17 CET 2009 firedtv: dvb demux: some simplifications c->active was unnecessarily cleared twice. Also, by marking the channel inactive before the for loop, the loop becomes identical with fdtv_channel_collect(). Sun Feb 15 15:33:17 CET 2009 firedtv: dvb demux: remove a bogus loop This loop is unnecessary because - only active channel[].pid's will be sent to the device, - when a channel is activated, its pid is set to dvbdmxfeed->pid. Perhaps the original code was there because it was initially not fully covered by the fdtv->demux_mutex. Sun Feb 15 15:33:17 CET 2009 firedtv: dvb demux: fix mutex protection fdtv_start_feed() accessed the channel list unsafely. Fully serialize it with itself and fdtv_stop_feed(). Sun Feb 15 15:33:17 CET 2009 firedtv: dvb demux: fix missing braces Original code was: ... case DMX_TS_PES_OTHER: //Dirty fix to keep firesat->channel pid-list up to date for(k=0;k<16;k++){ if(firesat->channel[k].active == 0) firesat->channel[k].pid = dvbdmxfeed->pid; break; } channel = firesat_channel_allocate(firesat); break; default: ... Looks bogus in several respects. For now let's just add braces to the if because that seems to be what the author meant. Sun Feb 15 15:33:17 CET 2009 firedtv: allow build without input subsystem !CONFIG_INPUT is very unlikely on systems on which firedtv is of interest. But we can easily support it. Sun Feb 15 15:33:17 CET 2009 firedtv: replace EXTRA_CFLAGS by ccflags The former are deprecated. The latter can depend on Kconfig variables. Sun Feb 15 15:33:17 CET 2009 firedtv: concentrate ieee1394 dependencies Move the entire interface with drivers/ieee1394 to firedtv-1394.c. Move 1394-independent module initialization code to firedtv-dvb.c. This prepares interfacing with drivers/firewire. Sun Feb 15 15:33:17 CET 2009 firedtv: amend Kconfig menu prompt Sun Feb 15 15:33:17 CET 2009 firedtv: remove kernel version compatibility macro Sun Feb 15 15:33:17 CET 2009 firedtv: combine header files avc.h and firedtv-*.h are small and currently not shared with other drivers, hence concatenate them all into firedtv.h. Sun Feb 15 15:33:17 CET 2009 firedtv: misc style touch-ups Standardize on lower-case hexadecimal constants. Adjust whitespace. Omit unnecessary pointer type casts and an unnecessary list head initialization. Use dev_printk. Wed Feb 11 21:21:04 CET 2009 firedtv: avc, ci: remove unused constants Wed Feb 11 21:21:04 CET 2009 firedtv: avc: remove bitfields from read descriptor response operands Don't use bitfields in struct types of on-the-wire data. Wed Feb 11 21:21:04 CET 2009 firedtv: avc: remove bitfields from DSD command operands Don't use bitfields in struct types of on-the-wire data. Wed Feb 11 21:21:04 CET 2009 firedtv: avc: header file cleanup Remove unused constants and declarations. Move privately used constants into .c files. Wed Feb 11 21:21:04 CET 2009 firedtv: avc: remove bitfields from FCP frame types Don't use bitfields in struct types of on-the-wire data. Also move many privately used constants from avc.h to avc.c and remove some unused constants. Sun, 18 Jan 2009 16:30:00 +0100 (CET) firedtv: avc: fix offset in avc_tuner_get_ts The parentheses were wrong. It didn't matter though because this code only writes a 0 into an area which is already initialized to 0. Sun, 18 Jan 2009 16:30:00 +0100 (CET) firedtv: avc: reduce stack usage, remove two typedefs It is safe to share a memory buffer for command frame and response frame because the response data come in after the command frame was last used. Even less stack would be required if only the actual required frame size instead of the entire FCP register size was allocated. Also, rename the defined types AVCCmdFrm and AVCRspFrm to struct avc_command_frame and struct avc_response_frame. TODO: Remove the bitfields in these types.

Signed-off-by: Beat Michel Liechti Change by Stefan R: combine it with case case FIREDTV_DVB_S as originally suggested by Beat Michel. This enables FE_CAN_FEC_AUTO also for FireDTV-S2 devices which is possible as long as only DVB-S channels are used. FE_CAN_FEC_AUTO would be wrong for DVB-S2 channels, but those cannot be used yet since the driver is not yet converted to S2API.

When doing recovery on a raid10 with a write-intent bitmap, we only need to recovery chunks that are flagged in the bitmap. However if we choose to skip a chunk as it isn't flag, the code currently skips the whole raid10-chunk, thus it might not recovery some blocks that need recovering. This patch fixes it. In case that is confusing, it might help to understand that there is a 'raid10 chunk size' which guides how data is distributed across the devices, and a 'bitmap chunk size' which says how much data corresponds to a single bit in the bitmap. This bug only affects cases where the bitmap chunk size is smaller than the raid10 chunk size.

For raid1/4/5/6, resync (fixing inconsistencies between devices) is very similar to recovery (rebuilding a failed device onto a spare). The both walk through the device addresses in order. For raid10 it can be quite different. resync follows the 'array' address, and makes sure all copies are the same. Recover walks through 'device' addresses and recreates each missing block. The 'bitmap_cond_end_sync' function allows the write-intent-bitmap (When present) to be updated to reflect a partially completed resync. It makes assumptions which mean that it does not work correctly for raid10 recovery at all. In particularly, it can cause bitmap-directed recovery of a raid10 to not recovery some of the blocks that need to be recovered. So move the call to bitmap_cond_end_sync into the resync path, rather than being in the common "resync or recovery" path.

There has been a race in raid10 and raid1 for a long time which has only recently started showing up due to a scheduler changed. When a sync_read request finishes, as soon as reschedule_retry is called, another thread can mark the resync request as having completed, so md_do_sync can finish, ->stop can be called, and ->conf can be freed. So using conf after reschedule_retry is not safe. Similarly, when finishing a sync_write, calling md_done_sync must be the last thing we do, as it allows a chain of events which will free conf and other data structures.

Commit fc8744adc870a8d4366908221508bb113d8b72ee "Stop playing silly games with the VM_ACCOUNT flag" changed shmem_file_setup() to set the shmem file's VM_ACCOUNT flag according to VM_NORESERVE not being set in the vma flags; but did so only _after_ the shmem_acct_size(flags, size) call which is expected to pre-account a shared anonymous object. It's all clearer if we switch shmem.c over to use VM_NORESERVE throughout in place of !VM_ACCOUNT. But I very nearly sent in a patch which mistakenly removed the accounting from tmpfs files: shmem_get_inode()'s memset was good for not setting VM_ACCOUNT, but now it needs to set VM_NORESERVE. Rather than setting that by default, then perhaps clearing it again in shmem_file_setup(), let's pass it as a flag to shmem_get_inode(): that allows us to remove the #ifdef CONFIG_SHMEM from shmem_file_setup().

I did some debugging (booting with no_console_suspend init=/bin/sh). Found that resume fails (2.6.28) with "serial number mismatch 'some garbage' != 'some other garbage'" and "revalidation failed" messages. That's because the controller firmware fills different serial number in the IDENTIFY every boot. The patch below fixes the resume simply clearing the serial number. The proper fix would be probably to fill in the serial number of the RAID volume instead. I assume that there must be something like that stored on the drives but I don't know where. Fix resume on pata_it821x RAID volume by clearing the serial number in IDENTIFY data, which is otherwise different on each boot.

If the bootloader has touched the SATA controller before starting Linux, Linux can end up enabling the SATA interrupt with events pending, which will cause the interrupt to be marked as spurious and then be disabled, which then breaks all further accesses to the controller. This patch makes the SoC path clear interrupt status on init like in the non-SoC case.

This commit allowed CPUs that have the CPU_FTR_UNALIGNED_LD_STD CPU feature bit present to do the memcpy() with unaligned load doubles. But, along with this came a bug where our final load double would read bytes beyond a page boundary and into the next (unmapped) page. This was caught by enabling CONFIG_DEBUG_PAGEALLOC, The fix was to read only the number of bytes that we need to store rather than reading a full 8-byte doubleword and storing only a portion of that. In order to minimise the amount of existing code touched we use the original do_tail for the src_unaligned case. Below is an example of the regression, as reported by Sachin Sant: Unable to handle kernel paging request for data at address 0xc00000003f380000 Faulting instruction address: 0xc000000000039574 cpu 0x1: Vector: 300 (Data Access) at [c00000003baf3020] pc: c000000000039574: .memcpy+0x74/0x244 lr: d00000000244916c: .ext3_xattr_get+0x288/0x2f4 [ext3] sp: c00000003baf32a0 msr: 8000000000009032 dar: c00000003f380000 dsisr: 40000000 current = 0xc00000003e54b010 paca = 0xc000000000a53680 pid = 1840, comm = readahead enter ? for help [link register ] d00000000244916c .ext3_xattr_get+0x288/0x2f4 [ext3] [c00000003baf32a0] d000000002449104 .ext3_xattr_get+0x220/0x2f4 [ext3] (unreliab le) [c00000003baf3390] d00000000244a6e8 .ext3_xattr_security_get+0x40/0x5c [ext3] [c00000003baf3400] c000000000148154 .generic_getxattr+0x74/0x9c [c00000003baf34a0] c000000000333400 .inode_doinit_with_dentry+0x1c4/0x678 [c00000003baf3560] c00000000032c6b0 .security_d_instantiate+0x50/0x68 [c00000003baf35e0] c00000000013c818 .d_instantiate+0x78/0x9c [c00000003baf3680] c00000000013ced0 .d_splice_alias+0xf0/0x120 [c00000003baf3720] d00000000243e05c .ext3_lookup+0xec/0x134 [ext3] [c00000003baf37c0] c000000000131e74 .do_lookup+0x110/0x260 [c00000003baf3880] c000000000134ed0 .__link_path_walk+0xa98/0x1010 [c00000003baf3970] c0000000001354a0 .path_walk+0x58/0xc4 [c00000003baf3a20] c000000000135720 .do_path_lookup+0x138/0x1e4 [c00000003baf3ad0] c00000000013645c .path_lookup_open+0x6c/0xc8 [c00000003baf3b70] c000000000136780 .do_filp_open+0xcc/0x874 [c00000003baf3d10] c0000000001251e0 .do_sys_open+0x80/0x140 [c00000003baf3dc0] c00000000016aaec .compat_sys_open+0x24/0x38 [c00000003baf3e30] c00000000000855c syscall_exit+0x0/0x40 Signed-off-by: Benjamin Herrenschmidt --- arch/powerpc/lib/memcpy_64.S | 26 ++++++++++++++++++++------ 1 file changed, 20 insertions(+), 6 deletions(-) diff --git a/arch/powerpc/lib/memcpy_64.S b/arch/powerpc/lib/memcpy_64.S index fe2d34e5332d..e178922b2c21 100644 --- a/arch/powerpc/lib/memcpy_64.S +++ b/arch/powerpc/lib/memcpy_64.S @@ -53,18 +53,19 @@ END_FTR_SECTION_IFCLR(CPU_FTR_UNALIGNED_LD_STD) 3: std r8,8(r3) beq 3f addi r3,r3,16 - ld r9,8(r4) .Ldo_tail: bf cr7*4+1,1f - rotldi r9,r9,32 + lwz r9,8(r4) + addi r4,r4,4 stw r9,0(r3) addi r3,r3,4 1: bf cr7*4+2,2f - rotldi r9,r9,16 + lhz r9,8(r4) + addi r4,r4,2 sth r9,0(r3) addi r3,r3,2 2: bf cr7*4+3,3f - rotldi r9,r9,8 + lbz r9,8(r4) stb r9,0(r3) 3: ld r3,48(r1) /* return dest pointer */ blr @@ -133,11 +134,24 @@ END_FTR_SECTION_IFCLR(CPU_FTR_UNALIGNED_LD_STD) cmpwi cr1,r5,8 addi r3,r3,32 sld r9,r9,r10 - ble cr1,.Ldo_tail + ble cr1,6f ld r0,8(r4) srd r7,r0,r11 or r9,r7,r9 - b .Ldo_tail +6: + bf cr7*4+1,1f + rotldi r9,r9,32 + stw r9,0(r3) + addi r3,r3,4 +1: bf cr7*4+2,2f + rotldi r9,r9,16 + sth r9,0(r3) + addi r3,r3,2 +2: bf cr7*4+3,3f + rotldi r9,r9,8 + stb r9,0(r3) +3: ld r3,48(r1) /* return dest pointer */ + blr .Ldst_unaligned: PPC_MTOCRF 0x01,r6 # put #bytes to 8B bdry into cr7 From f72b728bf100f276628e378e1fe6c6acd5d09401 Mon Sep 17 00:00:00 2001 From: Mark Nelson Date: Wed, 25 Feb 2009 13:46:24 +0000 Subject: [PATCH 089/176] powerpc: Fix 64bit __copy_tofrom_user() regression This fixes a regression introduced by commit a4e22f02f5b6518c1484faea1f88d81802b9feac ("powerpc: Update 64bit __copy_tofrom_user() using CPU_FTR_UNALIGNED_LD_STD").

The top 4 bits (this is a 36-bit bus) are hard wired to different values depending on the specific SoC in use. Our code used to work "by accident" until I added support for the ISA memory holes and while at it added more validity checking of the addresses. This patch should bring it back to working condition. It still relies on the device-tree being correct but that's somewhat a pre-requisite for anything to work anyway.

This will add the correct /sys/class/sound/cardN/device symlink, so HAL can see the device and ConsoleKit sets its ACL permissions for the logged-in user. For em28xx audio capture cards found e.g. in Hauppauge WinTV-HVR-900 (R2), this patch fixes errors like: ALSA lib pcm_hw.c:1429:(_snd_pcm_hw_open) Invalid value for card Error opening audio: Permission denied when running mplayer as a normal user.

There seems to be a problem on the interfaces or even inside the flexcop-device that can't handle interruption on the streaming interface. This patch adds a watchdog to check whether data is supposed to come in (streaming PIDs are requested) and if no data is seen within 400ms (default) it resets the streaming/pid-filtering hardware. This patch is urgently needed to support the rev 2.8 of the hardware and solves problem occassionally seen on older hardware.

It's safe to call ssb_pcicore_dev_irqvecs_enable() unconditionally, because it has internal checks for redundant calls.

This has two advantages: 1) A clean device shutdown is always desired here, because we disable the device's global crystal in the next statement. 2) This fixes a bug where the device will come up with the enable-bit set on the next initialization (without a reboot inbetween). This causes breakage on the second initialization due to code that checks this bit (ssb_device_is_enabled() checks).
