| * [POWERPC] re-enable OProfile for iSeries, using timer interruptKelly Daly2006-06-21
| | | | | | | | | | | | | | | | | | | | | | This patch removes the changes from an earlier patch that disables oProfile for iSeries within the oProfile KConfig (submitted Feb 23, 2006). Checks within the arch init for iSeries, still allowing profiling for timer interrupts (using firmware_has_feature).

| * [POWERPC] spufs: one more fix for 64k pagesarnd@arndb.de2006-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SPU context save/restore code is currently built for a 4k page size and we provide a _shipped version of it since most people don't have the spu toolchain that is needed to rebuild that code. This patch hardcodes the data structures to a 64k page alignment, which also guarantees 4k alignment but unfortunately wastes 60k of memory per SPU context that is created in the running system. We will follow up on this with another patch to reduce that overhead or maybe redo the context save/restore logic to do this part entirely different, but for now it should make experimental systems work with either page size.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SPU interrupt status must be cleared before handle it. Otherwise, kernel may drop some interrupt packet. Currently, class2 interrupt treated like: 1) call callback to wake up waiting process 2) mask raised mailbox interrupt 3) clear interrupt status I changed like: 1) mask raised mailbox interrupt 2) clear interrupt status 3) call callback to wake up waiting process Clearing status before masking will make spurious interrupt.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This changes the hypervisor abstraction of setting cpu affinity to a higher level to avoid platform dependent interrupt controller routines. I replaced spu_priv1_ops:spu_int_route_set() with a new routine spu_priv1_ops:spu_cpu_affinity_set(). As a by-product, this change eliminated what looked like an existing bug in the set affinity code where spu_int_route_set() mistakenly called int_stat_get().

| * [POWERPC] spufs: add a phys-id attribute to each SPU contextarnd@arndb.de2006-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For performance analysis, it is often interesting to know which physical SPE a thread is currently running on, and, more importantly, if it is running at all. This patch adds a simple attribute to each SPU directory with that information. The attribute is read-only and called 'phys-id'. It contains an ascii string with the number of the physical SPU (e.g. "0x5"), or alternatively the string "0xffffffff" (32 bit -1) when it is not running at all at the time that the file is read.

It doesn't yet handle some of the RAS interrupts (the ones described in iic_is/iic_irr), I'm still working on a proper way to expose these. They are essentially a cascaded controller by themselves (sic !) though I may just handle them locally to the iic driver. I need also to sync with David Erb on the way he hooked in the performance monitor interrupt. So that's all for 2.6.17 and I'll do more work on that with my rework of the powerpc interrupt layer that I'm hacking on at the moment.

| * [POWERPC] 64bit FPSCR supportAnton Blanchard2006-06-15
| | | | | | | | | | | | | | | | | | | | Forthcoming machines will extend the FPSCR to 64 bits. We already had a 64-bit save area for the FPSCR, but we need to use a new form of the mtfsf instruction. Fortunately this new form is decoded as an ordinary mtfsf by existing 64-bit processors. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
