| * [POWERPC] Generic BUG for powerpcJeremy Fitzhardinge2006-12-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes powerpc use the generic BUG machinery. The biggest reports the function name, since it is redundant with kallsyms, and not needed in general. There is an overall reduction of code, since module_32/64 duplicated several functions. Unfortunately there's no way to tell gcc that BUG won't return, so the BUG macro includes a goto loop. This will generate a real jmp instruction, which is never used.

| | * | [POWERPC] Add support for FP emulation for the e300c2 coreKim Phillips2006-12-08
| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The e300c2 has no FPU. Its MSR[FP] is grounded to zero. If an attempt is made to execute a floating point instruction (including floating-point load, store, or move instructions), the e300c2 takes a floating-point unavailable interrupt. This patch adds support for FP emulation on the e300c2 by declaring a new CPU_FTR_FP_TAKES_FPUNAVAIL, where FP unavail interrupts are intercepted and redirected to the ProgramCheck exception path for correct emulation handling. (If we run out of CPU_FTR bits we could look to reclaim this bit by adding support to test the cpu_user_features for PPC_FEATURE_HAS_FPU instead) It adds a nop to the exception path for 32-bit processors with a FPU.

This attempts to fix it as well as possible. The rule is supposed to be that pci_resource_to_user() always converts the resources back into a BAR values since that's what the /proc interface was supposed to deal with. However, for X to work on platforms where PCI MMIO is not mapped 1:1, it became a habit of platforms like powerpc to pass "fixed up" values there since X expects to be able to use values from /proc/bus/pci/devices as offsets to mmap of /dev/mem... So we keep that contraption here, causing also /sys/*/resource to expose fully absolute MMIO addresses instead of BAR values, which is ugly, but should still work as long as those are only used to calculate alignment within a page. X is still broken when built 32 bits on machines where PCI MMIO can be above 32-bit space unfortunately.

| * | [POWERPC] Define pci_unmap_addr() et al. when CONFIG_NOT_COHERENT_CACHE=yRoland Dreier2006-12-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current PowerPC code makes pci_unmap_addr(), pci_unmap_addr_set(), and friends trivial for all 32-bit kernels. This is reasonable, since for those kernels it is true that pci_unmap_single() does not need the DMA address from the original DMA mapping -- in fact, it is a NOP. However, I recently tried the tg3 driver on a PowerPC 440SPe machine, which runs a 32-bit kernel and has non-cache-coherent PCI DMA. I found that the tg3 driver crashed in pci_dma_sync_single_for_cpu(), since for non-coherent systems, that function must invalidate the cache for the DMA address range requested, and therefore it does use the address passed in. tg3 uses a DMA address it stashes away with pci_unmap_addr_set() and retrieves with pci_unmap_addr(). Of course, since pci_unmap_addr() is defined to (0) right now, this doesn't work. It seems to me that the tg3 driver is using pci_unmap_addr() in a legitimate way -- I wouldn't want to have to teach all drivers that they should use pci_unmap_addr() if they only need the address for unmapping functions, but if they want the pci_dma_sync functions, then they have to store the DMA address without the helper macros. The right fix therefore seems to be in the definition of the macros in <asm/pci.h> -- we should use the trivial versions only for 32-bit kernels for coherent systems, and the real versions for both 64-bit kernels and non-coherent systems.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to sort out our struct termios and add proper speed control we need to separate the kernel and user termios structures. Glibc is fine but the other libraries rely on the kernel exported struct termios and we need to extend this without breaking the ABI/API To do so we add a struct ktermios which is the kernel view of a termios structure and overlaps the struct termios with extra fields on the end for now. (That limitation will go away in later patches). Some platforms (eg alpha) planned ahead and thus use the same struct for both, others did not. This just adds the structures but does not use them, it seems a sensible splitting point for bisect if there are compile failures (not that I expect them) Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

| | | | | | | | | | | | | | | | | | | | | A few code paths need to check whether or not they are running on the PS3's LV1 hypervisor before making hcalls. This introduces a new firmware feature bit for this, FW_FEATURE_PS3_LV1. Now when both PS3 and IBM_CELL_BLADE are enabled, but not PSERIES, FW_FEATURE_PS3_LV1 and FW_FEATURE_LPAR get enabled at compile time, which is a bug. The same problem can also happen for (PPC_ISERIES && !PPC_PSERIES && PPC_SOMETHING_ELSE). In order to solve this, I introduce a new CONFIG_PPC_NATIVE option that is set when at least one platform is selected that can run without a hypervisor and then turns the firmware feature check into a run-time option. The new cell oprofile support that was recently merged does not work on hypervisor based platforms like the PS3, therefore make it depend on PPC_CELL_NATIVE instead of PPC_CELL.

* [POWERPC] cell: abstract spu management routinesGeoff Levand2006-12-04
| | | | | | | | | | | | | | | | | This adds a platform specific spu management abstraction and the coresponding routines to support the IBM Cell Blade. It also removes the hypervisor only resources that were included in struct spu. Three new platform specific routines are introduced, spu_enumerate_spus(), spu_create_spu() and spu_destroy_spu(). The underlying design uses a new type, struct spu_management_ops, to hold function pointers that the platform setup code is expected to initialize to instances appropriate to that platform. For the IBM Cell Blade support, I put the hypervisor only resources that were in struct spu into a platform specific data structure struct spu_pdata.

* [POWERPC] coredump: Add SPU elf notes to coredump.Dwayne Grant McConnell2006-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds SPU elf notes to the coredump. It creates a separate note for each of /regs, /fpcr, /lslr, /decr, /decr_status, /mem, /signal1, /signal1_type, /signal2, /signal2_type, /event_mask, /event_status, /mbox_info, /ibox_info, /wbox_info, /dma_info, /proxydma_info, /object-id. A new macro, ARCH_HAVE_EXTRA_NOTES, was created for architectures to specify they have extra elf core notes. A new macro, ELF_CORE_EXTRA_NOTES_SIZE, was created so the size of the additional notes could be calculated and added to the notes phdr entry. A new macro, ELF_CORE_WRITE_EXTRA_NOTES, was created so the new notes would be written after the existing notes. The SPU coredump code resides in spufs. Stub functions are provided in the kernel which are hooked into the spufs code which does the actual work via register_arch_coredump_calls(). A new set of __spufs_<file>_read/get() functions was provided to allow the coredump code to read from the spufs files without having to lock the SPU context for each file read from.

* [POWERPC] Distinguish POWER6 partition modes and tell userspacePaul Mackerras2006-12-04
| | | | | | | | | | | | | | | | | This adds code to look at the properties firmware puts in the device tree to determine what compatibility mode the partition is in on POWER6 machines, and set the ELF aux vector AT_HWCAP and AT_PLATFORM entries appropriately. Specifically, we look at the cpu-version property in the cpu node(s). If that contains a "logical" PVR value (of the form 0x0f00000x), we call identify_cpu again with this PVR value. A value of 0x0f000001 indicates the partition is in POWER5+ compatibility mode, and a value of 0x0f000002 indicates "POWER6 architected" mode, with various extensions disabled. We also look for various other properties: ibm,dfp, ibm,purr and ibm,spurr. Signed-off-by: Paul Mackerras <paulus@samba.org>
* [POWERPC] cell: Add oprofile supportMaynard Johnson2006-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add PPU event-based and cycle-based profiling support to Oprofile for Cell. Oprofile is expected to collect data on all CPUs simultaneously. However, there is one set of performance counters per node. There are two hardware threads or virtual CPUs on each node. Hence, OProfile must multiplex in time the performance counter collection on the two virtual CPUs. The multiplexing of the performance counters is done by a virtual counter routine. Initially, the counters are configured to collect data on the even CPUs in the system, one CPU per node. In order to capture the PC for the virtual CPU when the performance counter interrupt occurs (the specified number of events between samples has occurred), the even processors are configured to handle the performance counter interrupts for their node. The virtual counter routine is called via a kernel timer after the virtual sample time. The routine stops the counters, saves the current counts, loads the last counts for the other virtual CPU on the node, sets interrupts to be handled by the other virtual CPU and restarts the counters, the virtual timer routine is scheduled to run again. The virtual sample time is kept relatively small to make sure sampling occurs on both CPUs on the node with a relatively small granularity. Whenever the counters overflow, the performance counter interrupt is called to collect the PC for the CPU where data is being collected. The oprofile driver relies on a firmware RTAS call to setup the debug bus to route the desired signals to the performance counter hardware to be counted. The RTAS call must set the routing registers appropriately in each of the islands to pass the signals down the debug bus as well as routing the signals from a particular island onto the bus. There is a second firmware RTAS call to reset the debug bus to the non pass thru state when the counters are not in use.
