Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

sis5513: PIO mode setup fixes * limit max PIO mode to PIO4, this driver doesn't support PIO5 and attempt to program PIO5 by config_art_rwp_pio() could result in incorrect PIO timings being programmed and possibly the data corruption (for < ATA100 family chipsets PIO0 timings were used, for ATA100 and ATA100a - the random content of test1 variable was used, for ATA133 - MWDMA0 timings were used) * BUG() in sis5513_tune_chipset() if somebody tries to force unsupported PIO5, also cleanup this function a bit while at it * add comment about PIO0 timings for < ATA100 family chipsets * remove open-coded best PIO mode selection from config_art_rwp_pio(), it contained numerous bugs: - it didn't check for validity of id->eide_pio_modes and id->eide_pio_iordy before using them - it tried to found out maximum PIO mode basing on minimum IORDY cycle time (moreover wrong cycle times were used for PIO1/5) - it was overriding PIO blacklist and conservative PIO "downgrade" done by ide_get_best_pio_mode() * use sis5513_tune_drive() instead of config_art_rwp_pio() in sis5513_config_xfer_rate() so the correct PIO mode is also set on drive even if the device is not IORDY/DMA capable * config_art_rwp_pio() was always setting the best possible mode and not the wanted one - fix it and move ide_get_best_pio_mode() call to config_chipset_for_pio() * don't use ide_find_best_mode() in config_chipset_for_pio(), it was being overriden by config_art_rwp_pio() for the host timings anyway + we need to set the same PIO mode on the device and the host * pass correct "pio" argument (255 instead of 5) to sis5513_tune_drive() call in sis5513_config_xfer_rate() so the best PIO mode is set on the drive and not PIO4 * rename sis5513_tune_drive() to sis5513_tuneproc() and config_chipset_for_pio() to sis5513_tune_driver() * bump driver version Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

/*
* The original SiS5513 comes from a SiS5511/55112/5513 chipset. The original
* SiS5513 was also used in the SiS5596/5513 chipset. Thus if we see a SiS5511
* or SiS5596, we can assume we see the first MWDMA-16 capable SiS5513 chip.
*
* Later SiS chipsets integrated the 5513 functionality into the NorthBridge,
* starting with SiS5571 and up to SiS745. The PCI ID didn't change, though. We
* can figure out that we have a more modern and more capable 5513 by looking
* for the respective NorthBridge IDs.
*
* Even later (96x family) SiS chipsets use the MuTIOL link and place the 5513
* into the SouthBrige. Here we cannot rely on looking up the NorthBridge PCI
* ID, while the now ATA-133 capable 5513 still has the same PCI ID.
* Fortunately the 5513 can be 'unmasked' by fiddling with some config space
* bits, changing its device id to the true one - 5517 for 961 and 5518 for
* 962/963.

[PATCH] Small fixes backported to old IDE SiS driver Some quick backport bits from the libata PATA work to fix things found in the sis driver. The piix driver needs some fixes too but those are way to large and need someone working on old IDE with time to do them. This patch fixes the case where random bits get loaded into SIS timing registers according to the description of the correct behaviour from Vojtech Pavlik. It also adds the SiS5517 ATA16 chipset which is not currently supported by the driver. Thanks to Conrad Harriss for loaning me the machine with the 5517 chipset.

This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance.

PCI: Change all drivers to use pci_device->revision Instead of all drivers reading pci config space to get the revision ID, they can now use the pci_device->revision member. This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance. Compile tested with make all{yes,mod}config on x86_64 and i386.

We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

ide: add IDE_HFLAG_LEGACY_IRQS host flag Add IDE_HFLAG_LEGACY_IRQS host flag to tell ide_pci_setup_ports() to set hwif->irq to legacy IRQ 14/15 (iff hwif->irq is not already set) and convert atiixp, piix, serverworks, sis5513 and slc90e66 host drivers to use it. While at it: * In piix.c add IDE_HFLAGS_PIIX define and don't use ->init_hwif for MPIIX.

ide: add PIO masks * Add ATA_PIO[0-6] defines to <linux/ata.h>. * Add ->pio_mask field to ide_pci_device_t and ide_hwif_t. * Add PIO masks to host drivers. <linux/ata.h> change ACK-ed by Jeff Garzik <jeff@garzik.org>.

ide: add ->mwdma_mask and ->swdma_mask to ide_pci_device_t (take 2) * Add ->mwdma_mask and ->swdma_mask to ide_pci_device_t. * Set ide_hwif_t DMA masks using DMA masks from ide_pci_device_t in setup-pci.c::ide_pci_setup_ports() (iff DMA base is valid and ->init_hwif method may still override them). * Convert IDE PCI host drivers to use ide_pci_device_t DMA masks. While at it: * Use ATA_{UDMA,MWDMA,SWDMA}* defines. * hpt34x.c: add separate ide_pci_device_t instances for HPT343 and HPT345. * serverworks.c: fix DMA masks being set before checking DMA base. v2: * Add missing masks to DECLARE_GENERIC_PCI_DEV() macro.
