====================================
SGI IOC4 PCI (multi function) device
====================================
The SGI IOC4 PCI device is a bit of a strange beast, so some notes on
it are in order.
First, even though the IOC4 performs multiple functions, such as an
IDE controller, a serial controller, a PS/2 keyboard/mouse controller,
and an external interrupt mechanism, it's not implemented as a
multifunction device. The consequence of this from a software
standpoint is that all these functions share a single IRQ, and
they can't all register to own the same PCI device ID. To make
matters a bit worse, some of the register blocks (and even registers
themselves) present in IOC4 are mixed-purpose between these several
functions, meaning that there's no clear "owning" device driver.
The solution is to organize the IOC4 driver into several independent
drivers, "ioc4", "sgiioc4", and "ioc4_serial". Note that there is no
PS/2 controller driver as this functionality has never been wired up
on a shipping IO card.
ioc4
====
This is the core (or shim) driver for IOC4. It is responsible for
initializing the basic functionality of the chip, and allocating
the PCI resources that are shared between the IOC4 functions.
This driver also provides registration functions that the other
IOC4 drivers can call to make their presence known. Each driver
needs to provide a probe and remove function, which are invoked
by the core driver at appropriate times. The interface of these
IOC4 function probe and remove operations isn't precisely the same
as PCI device probe and remove operations, but is logically the
same operation.
sgiioc4
=======
This is the IDE driver for IOC4. Its name isn't very descriptive
simply for historical reasons (it used to be the only IOC4 driver
component). There's not much to say about it other than it hooks
up to the ioc4 driver via the appropriate registration, probe, and
remove functions.
ioc4_serial
===========
This is the serial driver for IOC4. There's not much to say about it
other than it hooks up to the ioc4 driver via the appropriate registration,
probe, and remove functions.

*
* There are 2 different structures to represent these boards -
* lboard - Local board, rboard - remote board. These 2 structures
* can be arbitrarily mixed in the LINKED LIST of BOARDs. (Refer
* Figure below). The first byte of the rboard or lboard structure
* is used to find out its type - no unions are used.
* If it is a lboard, then the config info of this board will be found
* on the local node. (LOCAL NODE BASE + offset value gives pointer to
* the structure.
* If it is a rboard, the local structure contains the node number
* and the offset of the beginning of the LINKED LIST on the remote node.
* The details of the hardware on a remote node can be built locally,
* if required, by reading the LINKED LIST on the remote node and
* ignoring all the rboards on that node.
*
* The local node uses the REMOTE NODE NUMBER + OFFSET to point to the
* First board info on the remote node. The remote node list is
* traversed as the local list, using the REMOTE BASE ADDRESS and not
* the local base address and ignoring all rboard values.

*
* Each BOARD consists of COMPONENTs and the BOARD structure has
* pointers (offsets) to its COMPONENT structure.
* The COMPONENT structure has version info, size and speed info, revision,
* error info and the NIC info. This structure can accommodate any
* BOARD with arbitrary COMPONENT composition.
*
* The ERRORINFO part of each BOARD has error information
* that describes errors about the BOARD itself. It also has flags to
* indicate the COMPONENT(s) on the board that have errors. The error
* information specific to the COMPONENT is present in the respective
* COMPONENT structure.
*
* The ERRORINFO structure is also treated like a COMPONENT, ie. the
* BOARD has pointers(offset) to the ERRORINFO structure. The rboard
* structure also has a pointer to the ERRORINFO structure. This is
* the place to store ERRORINFO about a REMOTE NODE, if the HUB on
* that NODE is not working or if the REMOTE MEMORY is BAD. In cases where
* only the CPU of the REMOTE NODE is disabled, the ERRORINFO pointer can
* be a NODE NUMBER, REMOTE OFFSET combination, pointing to error info
* which is present on the REMOTE NODE.(TBD)
* REMOTE ERRINFO can be stored on any of the nearest nodes
* or on all the nearest nodes.(TBD)
* Like BOARD structures, REMOTE ERRINFO structures can be built locally
* using the rboard errinfo pointer.
*
* In order to get useful information from this Data organization, a set of
* interface routines are provided (TBD). The important thing to remember while
* manipulating the structures, is that, the NODE number information should
* be used. If the NODE is non-zero (remote) then each offset should
* be added to the REMOTE BASE ADDR else it should be added to the LOCAL BASE ADDR.
* This includes offsets for BOARDS, COMPONENTS and ERRORINFO.
*
* Note that these structures do not provide much info about connectivity.
* That info will be part of HWGRAPH, which is an extension of the cfg_t
* data structure. (ref IP27prom/cfg.h) It has to be extended to include
* the IO part of the Network(TBD).
*
* The data structures below define the above concepts.

* PIC AS DEVICE ZERO
* ------------------
*
* PIC handles PCI/X busses. PCI/X requires that the 'bridge' (i.e. PIC)
* be designated as 'device 0'. That is a departure from earlier SGI
* PCI bridges. Because of that we use config space 1 to access the
* config space of the first actual PCI device on the bus.
* Here's what the PIC manual says:
*
* The current PCI-X bus specification now defines that the parent
* hosts bus bridge (PIC for example) must be device 0 on bus 0. PIC
* reduced the total number of devices from 8 to 4 and removed the
* device registers and windows, now only supporting devices 0,1,2, and
* 3. PIC did leave all 8 configuration space windows. The reason was
* there was nothing to gain by removing them. Here in lies the problem.
* The device numbering we do using 0 through 3 is unrelated to the device
* numbering which PCI-X requires in configuration space. In the past we
* correlated Configs pace and our device space 0 <-> 0, 1 <-> 1, etc.
* PCI-X requires we start a 1, not 0 and currently the PX brick
* does associate our:
*
* device 0 with configuration space window 1,
* device 1 with configuration space window 2,
* device 2 with configuration space window 3,
* device 3 with configuration space window 4.
*
* The net effect is that all config space access are off-by-one with
* relation to other per-slot accesses on the PIC.
* Here is a table that shows some of that:
*
* Internal Slot#
* |
* | 0 1 2 3
* ----------|---------------------------------------
* config | 0x21000 0x22000 0x23000 0x24000
* |
* even rrb | 0[0] n/a 1[0] n/a [] == implied even/odd
* |
* odd rrb | n/a 0[1] n/a 1[1]
* |
* int dev | 00 01 10 11

*
* CPUID - a number in range of 0..NR_CPUS-1 that uniquely identifies

* the boot cpu is 0.
* smp_processor_id() returns the cpuid of the current cpu.
*
* CPU_PHYSICAL_ID (also known as HARD_PROCESSOR_ID)
* This is the same as 31:24 of the processor LID register
* hard_smp_processor_id()- cpu_physical_id of current processor
* cpu_physical_id(cpuid) - convert a <cpuid> to a <physical_cpuid>
* cpu_logical_id(phy_id) - convert a <physical_cpuid> to a <cpuid>
* * not real efficient - don't use in perf critical code
*
* SLICE - a number in the range of 0 - 3 (typically) that represents the
* cpu number on a brick.
*
* SUBNODE - (almost obsolete) the number of the FSB that a cpu is
* connected to. This is also the same as the PI number. Usually 0 or 1.
*
* NOTE!!!: the value of the bits in the cpu physical id (SAPICid or LID) of a cpu has no
* significance. The SAPIC id (LID) is a 16-bit cookie that has meaning only to the PROM.
*
*
* The macros convert between cpu physical ids & slice/nasid/cnodeid.
* These terms are described below:
*
*
* Brick
* ----- ----- ----- ----- CPU
* | 0 | | 1 | | 0 | | 1 | SLICE
* ----- ----- ----- -----
* | | | |

/*
* DMA space
*
* The CA aperature (ie. bus address range) mapped by the GART is segmented into
* two parts. The lower portion of the aperature is used for mapping 32 bit
* PCI addresses which are managed by the dma interfaces in this file. The
* upper poprtion of the aperature is used for mapping 48 bit AGP addresses.
* The AGP portion of the aperature is managed by the agpgart_be.c driver
* in drivers/linux/agp. There are ca-specific hooks in that driver to
* manipulate the gart, but management of the AGP portion of the aperature
* is the responsibility of that driver.
*
* CA allows three main types of DMA mapping:
*
* PCI 64-bit Managed by this driver
* PCI 32-bit Managed by this driver
* AGP 48-bit Managed by hooks in the /dev/agpgart driver
*
* All of the above can optionally be remapped through the GART. The following
* table lists the combinations of addressing types and GART remapping that
* is currently supported by the driver (h/w supports all, s/w limits this):
*
* PCI64 PCI32 AGP48
* GART no yes yes
* Direct yes yes no
*
* GART remapping of PCI64 is not done because there is no need to. The
* 64 bit PCI address holds all of the information necessary to target any
* memory in the system.
*
* AGP48 is always mapped through the GART. Management of the AGP48 portion
* of the aperature is the responsibility of code in the agpgart_be driver.
*
* The non-64 bit bus address space will currently be partitioned like this:
*
* 0xffff_ffff_ffff +--------
* | AGP48 direct
* | Space managed by this driver
* CA_AGP_DIRECT_BASE +--------
* | AGP GART mapped (gfx aperature)
* | Space managed by /dev/agpgart driver
* | This range is exposed to the agpgart
* | driver as the "graphics aperature"
* CA_AGP_MAPPED_BASE +-----
* | PCI GART mapped
* | Space managed by this driver
* CA_PCI32_MAPPED_BASE +----
* | PCI32 direct
* | Space managed by this driver
* 0xC000_0000 +--------
* (CA_PCI32_DIRECT_BASE)
*
* The bus address range CA_PCI32_MAPPED_BASE through CA_AGP_DIRECT_BASE
* is what we call the CA aperature. Addresses falling in this range will
* be remapped using the GART.
*
* The bus address range CA_AGP_MAPPED_BASE through CA_AGP_DIRECT_BASE
* is what we call the graphics aperature. This is a subset of the CA
* aperature and is under the control of the agpgart_be driver.
*
* CA_PCI32_MAPPED_BASE, CA_AGP_MAPPED_BASE, and CA_AGP_DIRECT_BASE are
* somewhat arbitrary values. The known constraints on choosing these is:
*
* 1) CA_AGP_DIRECT_BASE-CA_PCI32_MAPPED_BASE+1 (the CA aperature size)
* must be one of the values supported by the ca_gart_aperature register.
* Currently valid values are: 4MB through 4096MB in powers of 2 increments
*
* 2) CA_AGP_DIRECT_BASE-CA_AGP_MAPPED_BASE+1 (the gfx aperature size)
* must be in MB units since that's what the agpgart driver assumes.
*/
/*
* Define Bus DMA ranges. These are configurable (see constraints above)
* and will probably need tuning based on experience.
*/
/*
* 11/24/03
* CA has an addressing glitch w.r.t. PCI direct 32 bit DMA that makes it
* generally unusable. The problem is that for PCI direct 32
* DMA's, all 32 bits of the bus address are used to form the lower 32 bits
* of the coretalk address, and coretalk bits 38:32 come from a register.
* Since only PCI bus addresses 0xC0000000-0xFFFFFFFF (1GB) are available
* for DMA (the rest is allocated to PIO), host node addresses need to be
* such that their lower 32 bits fall in the 0xC0000000-0xffffffff range
* as well. So there can be no PCI32 direct DMA below 3GB!! For this
* reason we set the CA_PCI32_DIRECT_SIZE to 0 which essentially makes
* tioca_dma_direct32() a noop but preserves the code flow should this issue
* be fixed in a respin.
*
* For now, all PCI32 DMA's must be mapped through the GART.
