| * [POWERPC] 85xxCDS: Delay 8259 cascade hookup.Randy Vinson2007-07-24
| | | | | | | | | | | | | | | | | | | | | | | | | | The interrupts of an E100 card inserted in PCI slot 4 may be on at bootup. The resulting interrupt flood interacts with the 8259 cascade handler and prevents proper boot up. There is a quirk for the E100 that will disable the E100's interrupts but to use it, the 8259 cascade hookup must be delayed until after the quirk has run. This patch delays the 8259 cascade hookup by registering a device_initcall() which runs after the PCI quirk for the E100.

| * [POWERPC] 85xxCDS: Make sure restart resets the PCI bus.Randy Vinson2007-07-23
| | | | | | | | | | | | | | | | | | | | | | | | | | The current 85xxCDS restart code fails to reset the PCI bus which can lead to odd behavior after the restart. This patch uses the VIA Super Southbridge to perform a PCI reset which will reset the entire system. NOTE: Since the VIA chip is behind a PCI-to-PCI bridge which can be disabled with a switch setting, it may not be possible to perform the PCI bus reset. In this case, the code defaults to the previous restart mechanism. Signed-off-by: Randy Vinson <rvinson@mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
| * [POWERPC] 85xxCDS: Allow 8259 cascade to share an MPIC interrupt line.Randy Vinson2007-07-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Freescale MPC8555CDS and MPC8548CDS reference hardware has a legacy 8259 interrupt controller pair contained within a VIA VT82C686B Southbridge on the main carrier board. The processor complex plugs into the carrier card using a PCI slot which limits the available interrupts to the INTA-INTD PCI interrupts. The output of the 8259 cascade pair is routed through a gate array and connected to the PCI INTA interrupt line. The normal interrupt chaining hook (set_irq_chained_handler) does not allow sharing of the chained interrupt which prevents the use of PCI INTA by PCI devices. This patch allows the 8259 cascade pair to share their interrupt line with PCI devices. NOTE: The addition of the .end routine for the MPIC is not strictly necessary for this patch. It's there so this code will run from within the threaded interrupt context used by the Real Time patch.

| * [POWERPC] FSL: Add support for PCI-X controllersKumar Gala2007-07-23
| | | | | | | | | | | | | | | | | | | | Some set of 85xx platforms have PCI-X controllers. The old arch/ppc code setup these controllers and we haven't moved it over to arch/powerpc. We use the PCI-X Capabilties to know if we are in PCI-X mode instead of the Global Utilities PORDEVSR. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | | | | | | Make it so we do a runtime check to know if we need to write cfg_addr as big or little endian. This is needed if we want to allow 86xx support to co-exist in the same kernel as other 6xx PPCs. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| * [POWERPC] 85xx: Add quirk to ignore bogus FPGA on CDSKumar Gala2007-07-23
| | | | | | | | | | | | | | | | | | | | | | | | The newer Arcadia boards for CDS have an FPGA that shows up on PCI however isn't a real PCI device. Add a quirk to just ignore the FPGA. This is based on the following patch from Andy & York: http://ozlabs.org/pipermail/linuxppc-dev/2007-February/032042.html Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | On the 85xx/86xx PCIe controllers if there is no device connected to the PHB we will still allocate a pci_bus for downstream bus of the virtual P2P bridge. However the resources allocated to the downstream bus are not correct and so we just mimic the resources from the upstream pci_bus. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| * [POWERPC] MPIC protected sourcesBenjamin Herrenschmidt2007-07-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some HW platforms, such as the new cell blades, requires some MPIC sources to be left alone by the operating system. This implements support for a "protected-sources" property in the mpic controller node containing a list of source numbers to be protected against operating system interference. For those interested in the gory details, the MPIC on the southbridge of those blades has some of the processor outputs routed to the cell, and at least one routed as a GPIO to the service processor. It will be used in the GA product for routing some of the southbridge error interrupts to the service processor which implements some of the RAS stuff, such as checkstopping when fatal errors occurs before they can propagate.

| * [POWERPC] Allow exec faults on readable areas on classic 32-bit PowerPCPaul Mackerras2007-07-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Classic 32-bit PowerPC CPUs, and the early 64-bit PowerPC CPUs, don't provide a way to prevent execution from readable pages, that is, the MMU doesn't distinguish between data reads and instruction reads, although a different exception is taken for faults in data accesses and instruction accesses. Commit 9ba4ace39fdfe22268daca9f28c5df384ae462cf, in the course of fixing another bug, added a check that meant that a page fault due to an instruction access would fail if the vma did not have the VM_EXEC flag set. This gives an inconsistent enforcement on these CPUs of the no-execute status of the vma (since reading from the page is sufficient to allow subsequent execution from it), and causes old versions of ppc32 glibc (2.2 and earlier) to fail, since they rely on executing the word before the GOT but don't have it marked executable. This fixes the problem by allowing execution from readable (or writable) areas on CPUs which do not provide separate control over data and instruction reads.

* [CELL] spufs: rework list management and associated lockingChristoph Hellwig2007-07-20
| | | | | | | | | | | | | | | | | | This sorts out the various lists and related locks in the spu code. In detail: - the per-node free_spus and active_list are gone. Instead struct spu gained an alloc_state member telling whether the spu is free or not - the per-node spus array is now locked by a per-node mutex, which takes over from the global spu_lock and the per-node active_mutex - the spu_alloc* and spu_free function are gone as the state change is now done inline in the spufs code. This allows some more sharing of code for the affinity vs normal case and more efficient locking - some little refactoring in the affinity code for this locking scheme Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>
* [CELL] oprofile: add support to OProfile for profiling CELL BE SPUsBob Nelson2007-07-20
| | | | | | | | | | | | | | | | | | | | | | | From: Maynard Johnson <mpjohn@us.ibm.com> This patch updates the existing arch/powerpc/oprofile/op_model_cell.c to add in the SPU profiling capabilities. In addition, a 'cell' subdirectory was added to arch/powerpc/oprofile to hold Cell-specific SPU profiling code. Exports spu_set_profile_private_kref and spu_get_profile_private_kref which are used by OProfile to store private profile information in spufs data structures. Also incorporated several fixes from other patches (rrn). Check pointer returned from kzalloc. Eliminated unnecessary cast. Better error handling and cleanup in the related area. 64-bit unsigned long parameter was being demoted to 32-bit unsigned int and eventually promoted back to unsigned long.

* [CELL] cell: indexing of SPUs based on firmware vicinity propertiesArnd Bergmann2007-07-20
| | | | | | | | | | | | | | | | | | | | | | | | | This patch links spus according to their physical position using information provided by the firmware through a special vicinity device-tree property. This property is present in current version of Malta firmware. Example of vicinity properties for a node in Malta: Node: Vicinity property contains phandles of: spe@0 [ spe@100000 , mic-tm@50a000 ] spe@100000 [ spe@0 , spe@200000 ] spe@200000 [ spe@100000 , spe@300000 ] spe@300000 [ spe@200000 , bif0@512000 ] spe@80000 [ spe@180000 , mic-tm@50a000 ] spe@180000 [ spe@80000 , spe@280000 ] spe@280000 [ spe@180000 , spe@380000 ] spe@380000 [ spe@280000 , bif0@512000 ] Only spe@* have a vicinity property (e.g., bif0@512000 and mic-tm@50a000 do not have it).
