* powerpc/44x: Add PowerPC 44x simple platform supportJosh Boyer2008-08-28
| | | | | | | | | | | This adds a common board file for almost all of the "simple" PowerPC 44x boards that exist today. This is intended to be a single place to add support for boards that do not differ in platform support from most of the evaluation boards that are used as reference platforms. Boards that have specific requirements or custom hardware setup should still have their own board.c file. Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>

* powerpc: Expose PMCs & cache topology in sysfs on 32-bitBenjamin Herrenschmidt2008-08-20
| | | | | | | | | | | | | | | The file arch/powerpc/kernel/sysfs.c is currently only compiled for 64-bit kernels. It contain code to register CPU sysdevs in sysfs and add various properties such as cache topology and raw access by root to performance monitor counters (PMCs). A lot of that can be re-used as is on 32-bits. This makes the file be built for both, with appropriate ifdef'ing for the few bits that are really 64-bit specific, and adds some support for the raw PMCs for 75x and 74xx processors.

* powerpc: Remove redundant sysfs_remove_file calls for cache infoNathan Lynch2008-08-20
| | | | | | | | | | | When removing a directory, the sysfs core takes care of removing files in the directory (see sysfs_remove_dir()). So when we are about to delete a kobject (and thus cause its sysfs directory to be removed), we don't have to explicitly remove the files attached to it, although it's harmless to do so.

* powerpc: Update in-kernel dtc and libfdt to version 1.2.0David Gibson2008-08-20
| | | | | | | | | | | | | Some time ago, a copies of the upstream dtc and libfdt sources were included in the kernel tree to avoid having these as external dependencies for building the kernel. Since then development on the upstream dtc and libfdt has continued. This updates the in-kernel versions to match the recently released upstream dtc version 1.2.0.

* powerpc: Convert the MPIC MSI code to use msi_bitmapMichael Ellerman2008-08-20
| | | | | | | | | | | This affects the U3 MSI code as well as the PASEMI MSI code. We keep some of the MPIC routines as helpers, and also the U3 best-guess reservation logic.

* powerpc: Split-out common MSI bitmap logic into msi_bitmap.cMichael Ellerman2008-08-20
| | | | | | | | | | | | | | | | | | | | | | | | | | There are now two almost identical implementations of an MSI bitmap allocator, one in mpic_msi.c and the other in fsl_msi.c. Merge them together and put the result in msi_bitmap.c. Some of the MPIC bits will remain to provide a nicer interface for the MPIC users. In the process we fix two buglets. The first is that the allocation routines, now msi_bitmap_alloc_hwirqs(), returned an unsigned result, even though they use -1 to indicate allocation failure. Although all the callers were checking correctly, it is much better for the routine to just return an int. At least until someone wants > ~2 billion MSIs. The second buglet is that the device tree reservation logic only allowed power-of-two reservations. AFAICT that didn't effect any existing code but it's nicer if we can reserve arbitrary irqs from MSI use. We also add some selftests, which exposed the two buglets and now test for them, as well as some basic sanity tests. The tests are only built when CONFIG_DEBUG_KERNEL=y.

* powerpc: Streamline ret_from_except_lite for non-iSeries platformsMichael Ellerman2008-08-20
| | | | | | | | | | | | | | | There is a small passage of code in ret_from_except_lite which is only required on iSeries. For a multi-platform kernel on non-iSeries machines this means we end up executing ~15 nops in ret_from_except_lite. It would be nicer if non-iSeries could skip the code entirely, and on iSeries we can jump out of line to execute the code. I have no performance numbers to justify this, other than the assertion that executing 15 nops takes longer than executing 0.

* powerpc: Fix vio_bus_probe oops on probe errorBrian King2008-08-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When CMO is enabled and booted on a non CMO system and the VIO device's probe function fails, an oops can result since vio_cmo_bus_remove is called when it should not. This fixes it by avoiding the vio_cmo_bus_remove call on platforms that don't implement CMO. cpu 0x0: Vector: 300 (Data Access) at [c00000000e13b3d0] pc: c000000000020d34: .vio_cmo_bus_remove+0xc0/0x1f4 lr: c000000000020ca4: .vio_cmo_bus_remove+0x30/0x1f4 sp: c00000000e13b650 msr: 8000000000009032 dar: 0 dsisr: 40000000 current = 0xc00000000e0566c0 paca = 0xc0000000006f9b80 pid = 2428, comm = modprobe enter ? for help [c00000000e13b6e0] c000000000021d94 .vio_bus_probe+0x2f8/0x33c [c00000000e13b7a0] c00000000029fc88 .driver_probe_device+0x13c/0x200 [c00000000e13b830] c00000000029fdac .__driver_attach+0x60/0xa4 [c00000000e13b8c0] c00000000029f050 .bus_for_each_dev+0x80/0xd8 [c00000000e13b980] c00000000029f9ec .driver_attach+0x28/0x40 [c00000000e13ba00] c00000000029f630 .bus_add_driver+0xd4/0x284 [c00000000e13baa0] c0000000002a01bc .driver_register+0xc4/0x198 [c00000000e13bb50] c00000000002168c .vio_register_driver+0x40/0x5c [c00000000e13bbe0] d0000000003b3f1c .ibmvfc_module_init+0x70/0x109c [ibmvfc] [c00000000e13bc70] c0000000000acf08 .sys_init_module+0x184c/0x1a10 [c00000000e13be30] c000000000008748 syscall_exit+0x0/0x40 Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc/ibmebus: Restore "name" sysfs attribute on ibmebus devicesJoachim Fenkes2008-08-19
| | | | | | | | | | | | | | | Recent of_platform changes made of_bus_type_init() overwrite the bus type's .dev_attrs list, meaning that the "name" attribute that ibmebus devices previously had is no longer present. This is a user-visible regression which breaks the userspace eHCA support, since the eHCA userspace driver relies on the name attribute to check for valid adapters. This fixes it by providing the "name" attribute in the generic OF device code instead. Tested on POWER.

| | | | | | | | | | | | | | | | | | | | | | | | | | Based on an original patch from Christoph Hellwig <hch@lst.de>. Currently, there is a possible reference-after-free in the spusched code - contexts may be freed after we have released their state_mutex in spusched_tick and find_victim. This change takes a reference to the context before releasing the mutex, so that the context doesn't get destroyed. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
| * powerpc/spufs: fix npc setting for NOSCHED contextsJeremy Kerr2008-08-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, spu_run ignores the npc argument for contexts created with SPU_CREATE_NOSCHED. While this is correct for isolated contexts, there's no need to enforce the npc restriction on non-isolated NOSCHED contexts. This means that NOSCHED contexts can only ever run with an entry point of 0x0. This change to spu_run_init allows setting of the npc (and, while we're at it, the privcntl) for non-isolated NOSCHED contexts. This allows us to run NOSCHED contexts from any entry point.

| * | | powerpc: Use generic compat_sys_old_readdirChristoph Hellwig2008-08-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the generic compat_sys_old_readdir instead of the powerpc one which is almost the same except for the almost complete lack of error handling. Note that we can't just use SYSCALL() in systbl.h because the native syscall is named old_readdir, not sys_old_readdir.

There is a static module_find_bug in lib/bug.c but that is a separate issue. Signed-off-by: Steven Rostedt <srostedt@redhat.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a field in lparcfg output to indicate whether the kernel is running on a dedicated or shared memory lpar. Added fields to show the paging space pool IDs and the CMO page size. Submitted-by: Robert Jennings <rcj@linux.vnet.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
| * | | powerpc: Fix CMM page loaning on 64k page kernel with 4k hardware pagesBrian King2008-08-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the firmware page size used for collaborative memory overcommit is 4k, but the kernel is using 64k pages, the page loaning is currently broken as it only marks the first 4k page of each 64k page as loaned. This fixes this to iterate through each 4k page and mark them all as loaned/active.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During platform setup, save off the primary/secondary paging space pool IDs and the page size. Added accessors in hvcall.h for these variables. This is needed for a subsequent fix. Submitted-by: Robert Jennings <rcj@linux.vnet.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A small bogon sneaked into the ppc64 lockdep support. A test is branching slightly off causing a clobbered register value to overwrite the irq state under some circumstances.

| * | | powerpc: Fix TLB invalidation on boot on 32-bitRocky Craig2008-08-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The intent of "flush_tlbs" is to invalidate all TLB entries by doing a TLB invalidate instruction for all pages in the address range 0 to 0x00400000. A loop counter is set up at the high value and decremented by page size. However, the loop is only done once as the sense of the conditional branch at the loop end does not match the setup/decrement. This fixes it to do the whole range by correcting the branch condition. Signed-off-by: Rocky Craig <rocky.craig@hp.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
