2009-05-15powerpc: Fix PCI ROM accessBenjamin Herrenschmidt
A couple of issues crept in since about 2.6.27 related to accessing PCI device ROMs on various powerpc machines. First, historically, we don't allocate the ROM resource in the resource tree. I'm not entirely certain of why, I susepct they often contained garbage on x86 but it's hard to tell. This causes the current generic code to always call pci_assign_resource() when trying to access the said ROM from sysfs, which will try to re-assign some new address regardless of what the ROM BAR was already set to at boot time. This can be a problem on hypervisor platforms like pSeries where we aren't supposed to move PCI devices around (and in fact probably can't). Second, our code that generates the PCI tree from the OF device-tree (instead of doing config space probing) which we mostly use on pseries at the moment, didn't set the (new) flag IORESOURCE_SIZEALIGN on any resource. That means that any attempt at re-assigning such a resource with pci_assign_resource() would fail due to resource_alignment() returning 0. This fixes this by doing these two things: - The code that calculates resource flags based on the OF device-node is improved to set IORESOURCE_SIZEALIGN on any valid BAR, and while at it also set IORESOURCE_READONLY for ROMs since we were lacking that too - We now allocate ROM resources as part of the resource tree. However to limit the chances of nasty conflicts due to busted firmwares, we only do it on the second pass of our two-passes allocation scheme, so that all valid and enabled BARs get precedence. This brings pSeries back the ability to access PCI ROMs via sysfs (and thus initialize various video cards from X etc...). Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2009-05-15powerpc/pseries: Really fix the oprofile CPU type on pseriesBenjamin Herrenschmidt
My previous pach for fixing the oprofile CPU type got somewhat mismerged (by my fault) when it collided with another related patch. This should finally (fingers crossed) fix the whole thing. We make sure we keep the -old- oprofile type and CPU type whenever one of them was specified in the first pass through the function. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2009-05-15powerpc/cell: Make ptcal more reliableGerhard Stenzel
There have been a series of checkstops on QS21 related to ptcal being set up incorrectly. On systems that only have memory on a single node, ptcal fails when it gets a pointer to memory on the remote node. Moreover, agressive prefetching in memcpy and other functions may accidentally touch the first cache line of the page that we reserve for ptcal, which causes an ECC checkstop. We now allocate pages only from the specified node, moves the ptcal area into the middle of the allocated page to avoid potential prefetch problems and prints the address of the ptcal area to facilitate diagnostics.

2009-05-15powerpc/mpic: Fix incorrect allocation of interrupt rev-mapKumar Gala
Before when we were setting up the irq host map for mpic we passed in just isu_size for the size of the linear map. However, for a number of mpic implementations we have no isu (thus pass in 0) and will end up with a no linear map (size = 0). This causes us to always call irq_find_mapping() from mpic_get_irq(). By moving the allocation of the host map to after we've determined the number of sources we can actually benefit from having a linear map for the non-isu users that covers all the interrupt sources.

2009-05-15powerpc: Fix oprofile sampling of marked events on POWER7Maynard Johnson
Description ----------- Change ppc64 oprofile kernel driver to use the SLOT bits (MMCRA[37:39]only on older processors where those bits are defined. Background ---------- The performance monitor unit of the 64-bit POWER processor family has the ability to collect accurate instruction-level samples when profiling on marked events (i.e., "PM_MRK_<event-name>"). In processors prior to POWER6, the MMCRA register contained "slot information" that the oprofile kernel driver used to adjust the value latched in the SIAR at the time of a PMU interrupt. But as of POWER6, these slot bits in MMCRA are no longer necessary for oprofile to use, since the SIAR itself holds the accurate sampled instruction address. With POWER6, these MMCRA slot bits were zero'ed out by hardware so oprofile's use of these slot bits was, in effect, a NOP. But with POWER7, these bits are no longer zero'ed out; however, they serve some other purpose rather than slot information. Thus, using these bits on POWER7 to adjust the SIAR value results in samples being attributed to the wrong instructions. The attached patch changes the oprofile kernel driver to ignore these slot bits on all newer processors starting with POWER6.

2009-05-15powerpc/iseries: Fix pci breakage due to bad dma_data initializationStephen Rothwell x
Commit 4fc665b88a79a45bae8bbf3a05563c27c7337c3d "powerpc: Merge 32 and 64-bit dma code" made changes to the PCI initialisation code that added an assignment to archdata.dma_data but only for 32 bit code. Commit 7eef440a545c7f812ed10b49d4a10a351df9cad6 "powerpc/pci: Cosmetic cleanups of pci-common.c" removed the conditional compilation. Unfortunately, the iSeries code setup the archdata.dma_data before that assignment was done - effectively overwriting the dma_data with NULL. Fix this up by moving the iSeries setup of dma_data into a pci_dma_dev_setup callback.

2009-05-02Move dtc and libfdt sources from arch/powerpc/boot to scripts/dtcDavid Gibson
The powerpc kernel always requires an Open Firmware like device tree to supply device information. On systems without OF, this comes from a flattened device tree blob. This blob is usually generated by dtc, a tool which compiles a text description of the device tree into the flattened format used by the kernel. Sometimes, the bootwrapper makes small changes to the pre-compiled device tree blob (e.g. filling in the size of RAM). To do this it uses the libfdt library. Because these are only used on powerpc, the code for both these tools is included under arch/powerpc/boot (these were imported and are periodically updated from the upstream dtc tree). However, the microblaze architecture, currently being prepared for merging to mainline also uses dtc to produce device tree blobs. A few other archs have also mentioned some interest in using dtc. Therefore, this patch moves dtc and libfdt from arch/powerpc into scripts, where it can be used by any architecture. The vast bulk of this patch is a literal move, the rest is adjusting the various Makefiles to use dtc and libfdt correctly from their new locations.

2009-04-28powerpc: ppc32 needs elf_read_implies_exec()Kumar Gala
On ppc64 we implemented elf_read_implies_exec() for 32-bit binaries because old toolchains had bugs where they didn't mark program segments executable that needed to be. For some reason we didn't do this on ppc32 builds. This hadn't been an issue until commit 8d30c14c ("powerpc/mm: Rework I$/D$ coherency (v3)"), which had as a side effect that we are now enforcing execute permissions to some extent on 32-bit 4xx and Book E processors. This fixes it by defining elf_read_implies_exec on 32-bit to turn on the read-implies-exec behaviour on programs that are sufficiently old that they don't have a PT_GNU_STACK program header.

2009-04-21powerpc: don't disable SATA interrupts on Freescale MPC8610 HPCDTimur Tabi
The ULI 1575 PCI quirk function for the Freescale MPC8610 HPCD was disabling the SATA INTx interrupt, even when SATA support was enabled. This was safe, because the SATA driver re-enabled it. But with commit a5bfc471 ("ahci: drop intx manipulation on msi enable"), the driver no longer does this, and so SATA support on the 8610 HPCD is broken. The original quirk function disabled INTx because it caused some other interrupt problem during early development on this board, but no one remembers any more what that problem was, and it doesn't seem to occur any more.
