* [POWERPC] Fix PowerPC 750CL and 750GX CPU featuresJosh Boyer2007-04-241-2/+2
| | | | | | | | | | | PowerPC 750CL has high BATs. The patch below adds a CPU_FTRS_750CL that includes that. Without it, the original firmware mappings in the high BATs aren't cleared which continue to override the linux translations. It also adds CPU_FTR_COMMON to CPU_FTRS_750GX for completeness.

| * [POWERPC] cell: enable RTAS-based PTCAL for Cell XDR memoryJeremy Kerr2007-04-231-0/+160
| | | | | | | | | | | | | | | | | | | | | | | | Enable Periodic Recalibration (PTCAL) support for Cell XDR memory, using the new ibm,cbe-start-ptcal and ibm,cbe-stop-ptcal RTAS calls. Tested on QS20 and QS21 (by Thomas Huth). It seems that SLOF has problems disabling, at least on QS20; this patch should only be used once these problems have been addressed.

| | | | | | | | | | | | | | | | | | | | At the moment the pmi device driver is probing for devices with a given type and a given name.

| | | | | | | | | | | | | | | | | | | | | | This patch adds a check for the private driver data to be initialized. The bug showed up, as the caller found a pmi device by it's type. Whereas the pmi driver probes for the type and the name. Since the name was not as the driver expected, it did not initialize. A more relaxed probing will be supplied with an extra patch, too.

This has multiple bad side-effects: - it becomes impossible to suspend the context during page faults - if an spu program attempts to access its own mmio areas through DMA, we get an immediate livelock when the nopage function tries to acquire the same mutex This patch makes the page fault logic operate on a struct spu_context instead of a struct spu, and moves it from spu_base.c to a new file fault.c inside of spufs. We now also need to copy the dar and dsisr contents of the last fault into the saved context to have it accessible in case we schedule out the context before activating the page fault handler.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For quite a while now spu state is protected by a simple mutex instead of the old rw_semaphore, and this means we can simplify the locking around spu_setup_isolated a lot. Instead of doing an spu_release before entering spu_setup_isolated and then calling the complicated spu_acquire_exclusive we can now simply enter the function locked an in guaranteed runnable state, so that the only bit of spu_acquire_exclusive that's left is the call to spu_unmap_mappings. Similarly there's no more need to unlock and reacquire the state_mutex when spu_setup_isolated is done, but we can always return with the lock held and only drop it in spu_run_init in the failure case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 79c8541924a220964f9f2cbed31eaa9fdb042eab introduced code to move the initrd if it was in a place where it would get overwritten by the kernel image. Unfortunately this exposed the fact that the code that checks whether the values passed in r3 and r4 are intended to indicate the start address and size of an initrd image was not as thorough as the kernel's checks. The symptom is that on OF-based platforms, the bootwrapper can cause an exception which causes the system to drop back into OF. Previously it didn't matter so much if the code incorrectly thought that there was an initrd, since the values for start and size were just passed through to the kernel. Now the bootwrapper needs to apply the same checks as the kernel since it is now using the initrd data itself (in the process of copying it if necessary). This adds the code to do that.

* | [POWERPC] ibmebus: change probe/remove interface from using loc-code to DT pathJoachim Fenkes2007-04-131-55/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases, multiple OFDT nodes might share the same location code, so the location code is not a unique identifier for an OFDT node. Changed the ibmebus probe/remove interface to use the DT path of the device node instead of the location code. The DT path must be written into probe/remove right as it would appear in the "devspec" attribute of the ebus device: relative to the DT root, with a leading slash and without a trailing slash. One trailing newline will not hurt; multiple newlines will (like perl's chomp()). Example: Add a device "/proc/device-tree/foo@12345678" to ibmebus like this: echo /foo@12345678 > /sys/bus/ibmebus/probe Remove the device like this: echo /foo@12345678 > /sys/bus/ibmebus/remove Signed-off-by: Joachim Fenkes <fenkes@de.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
