Support for PA6T-style PMC registers. PMCs are completely implementation-dependent on PPC, and PA6T numbers them differently from the IBM model. Signed-off-by:

Introduce _SYSDEV_ATTR(), to be used to just define the struct, and not a named variable with the attribute. Useful for arrays of sysdev_attributes. Signed-off-by:

Add cputable entries for which type of PMC implementation the processor has. I've only filled in the current 64-bit processors, the unfilled default value will have same behaviour as before so it can be done over time as needed. Also tidy up the dummy_perf implementation a bit, aggregating it into one function with ifdefs instead of several. Signed-off-by:

Clean up the ctr_read/write a bit. It's currently defined in the include but only used in one C file each. The only exception is the classic version, so keep that in the include and define in the C file as appropriate. Signed-off-by:

The grow() function in the rheap library allocates a larger array of blocks, copies the contents of the old blocks array to the newly allocated array and fixes the list_head pointers after the copy. At the end, the new blocks must be enqueued to the empty_list of the rh_info_t structure. This patch fixes a bug where the code was indexing past the end of the array when enqueueing blocks. The UCC ethernet driver, which uses the rheap allocator, experiences kernel panics because of this bug. Signed-off-by:

PS3 interrupt core update: - Add ps3_alloc_irq() and ps3_free_irq(), to allocate a virtual interrupt number for an interrupt outlet, which is needed by the PS3 GPU frame buffer device and audio drivers Signed-off-by: -

Change the PS3 irq allocation routines to take an argument indicating which cpu (processor thread) the interrupt should be serviced on. The current system configuration favors device interrupts that are serviced on cpu0, so that is used as the default. Signed-off-by:

Fix two minor bugs in the PS3 system bus mmio region code. First, on error or when freeing a region, retain the bus_addr and len fields to allow subsequent calls to create the region. Second, correct the region address argument to the lv1_unmap_device_mmio_region() call. Fixes modprobe/rmmod of some drivers. Signed-off-by:

Handle storage-related repository data: - Add missing implementations of ps3_repository_read_stor_*() repository accessors. - Dump storage properties in debug mode - Add PS3_DEV_TYPE_STOR_{DISK,ROM,FLASH} device types (which are identical to the corresponding SCSI device types) to enum ps3_dev_type Signed-off-by: -
Geoff Levand authored
Various fixes for the PS3 repository code: - Sync signatures of function prototypes and implementations (enum vs. unsigned int) - Correct references to `regions' as `registers': o Correct enum ps3_region_type as enum ps3_reg_type, o Correct PS3_REGION_TYPE_* as PS3_REG_TYPE_*, o Correct ps3_repository_find_region() as ps3_repository_find_reg(). - Correct function name in pr_debug() call - Minor error condition improvements.

It appears that EEH is improperly enabled for some Power4 systems. On these systems, the ibm,set-eeh-option returns a value of success even when EEH is not supported on the given node. Thus, an explicit check for support is required. During boot, on power4, without this patch, one sees messages similar to: EEH: event on unsupported device, rc=0 dn=/pci@400000000110/IBM,sp@1 EEH: event on unsupported device, rc=0 dn=/pci@400000000110/pci@2 EEH: event on unsupported device, rc=0 dn=/pci@400000000110/pci@2,2 etc. The patch makes these go away. Without this patch, EEH recovery does seem to work correctly for at least some devices (I tested ethernet e1000), but fails to recover others (the Emulex LightPulse LPFC, most notably). Off the top of my head, I don't remember why some devices are affected, but not others. The PAPR indicates that the correct way to test for EEH is as done in this patch; its not clear to me if this was in the PAPR all along, or recently added; if it was there all along, its not clear to me why this hadn't been fixed long ago. I suspect only certain firmware levels are affected. Signed-off-by:

This adds the core 8xx stuff and specifically mpc885ads board-specific bits to arch/powerpc. Respective Kconfig has been cleaned up from the stuff not yet ported over to avoid confusion. Updated and cleaned version. Signed-off-by:

Including support for non-coherent cache, some mm-related things + relevant field in Kconfig and Makefiles. Also included rheap.o compilation if 8xx is defined. Non-coherent mapping were refined and renamed according to Cristoph Hellwig. Orphaned functions were cleaned up. [Also removed arch/ppc/kernel/dma-mapping.c, because otherwise compiling with ARCH=ppc for a non DMA-cache-coherent platform ends up with two copies of __dma_alloc_coherent etc. -- paulus.] Signed-off-by:

This is just a straight port of the same done in arch/ppc by Marcelo Tosatti. One used to be [PATCH] ppc32 8xx: update_mmu_cache() needs unconditional tlbie, commit eb07d964 In a nutshell, the board is nearly stuck without this, yet without any visible failure - being just very slow. Signed-off-by:

This makes cpm uart able to work using OF-passed parameters in case of CPM stuff (found on most mpc8xx reference and custom boards). The idea is to keep ppc stuff working yet making it able to be used for powerpc. Signed-off-by:

It's useful to have access to struct ipic handle that just got created in ipic_init(). For example, if we want to setup an external IRQ with out a device node we need access ipic->irqhost to create the virtual to HW IRQ mapping and to set the IRQ sense. With this we can mimic the old sense array concept that existed in arch/ppc. Signed-off-by: -

Make the various 83xx *_init_IRQ() functions static Signed-off-by: -
Kumar Gala authored
It's possibly that we get an reset requestion when interrupts are disabled. (For example an oops in an interrupt handler). Therefor, we can't call ioremap in the reset function. Moving the ioremap of the registers we need access to an arch_initcall helps the problem. However we still have a window between boot and the arch_initcall in which the register pointer will not be setup and thus we spin if the reset function is called. If one needs to ensure even this case is covered, look at use of the watchdog provided on 83xx to reset the processor. Signed-off-by:
