* powerpc: Move defconfig over and remove remaining arch/ppc64 filesPaul Mackerras2005-11-187-7353/+0
| | | | | | | | make defconfig will now use arch/powerpc/configs/ppc64_defconfig if running on a ppc64 system. I need to add an arch/powerpc/configs/ppc_defconfig sometime. Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc: Move remaining .c files from arch/ppc64 to arch/powerpcPaul Mackerras2005-11-184-1012/+0
| | | | | | | | | | | This also deletes the now-unused Makefiles under arch/ppc64. Both of the files moved over could use some merging, but for now I have moved them as-is and arranged for them to be used only in 64-bit kernels. For 32-bit kernels we still use arch/ppc/kernel/idle.c and drivers/char/generic_nvram.c as before. Signed-off-by: Paul Mackerras <paulus@samba.org>
* [PATCH] powerpc: merge align.cBenjamin Herrenschmidt2005-11-182-397/+1
| | | | | | | | | | | | | | This patch merges align.c, the result isn't quite what was in ppc64 nor what was in ppc32 :) It should implement all the functionalities of both though. Kumar, since you played with that in the past, I suppose you have some test cases for verifying that it works properly before I dig out the 601 machine ? :) Since it's likely that I won't be able to test all scenario, code inspection is much welcome.

* powerpc: Move ppc64 boot wrapper code over to arch/powerpcPaul Mackerras2005-11-1617-2172/+0
| | | | | | | | This also extends the code to handle 32-bit ELF vmlinux files as well as 64-bit ones. This is sufficient for booting on new-world 32-bit powermacs (i.e. all recent machines). Signed-off-by: Paul Mackerras <paulus@samba.org>

* [PATCH] powerpc: kill ppc64 rtc.c, use genrtc insteadBenjamin Herrenschmidt2005-11-142-359/+0
| | | | | | | | | | | This moves the rtas RTC callbacks to rtas-rtc.c in arch/powerpc/kernel, and kills the rest of arch/ppc64/kernel/rtc.c which was just a duplicate of the genrtc functionality. Also enable build of genrtc for CONFIG_PPC64 (it just works are we already have the required callbacks) and enable it in all defconfigs.

* [PATCH] powerpc: Export htab start/end via device treeMichael Ellerman2005-11-141-0/+51
| | | | | | | | | | | The userspace kexec-tools need to know the location of the htab on non-lpar machines, as well as the end of the kernel. Export via the device tree. NB. This patch has been updated to use "linux,x" property names. You may need to update your kexec-tools to match.

* [PATCH] powerpc: Turn cpu_irq_down into kexec_cpu_downMichael Ellerman2005-11-141-6/+6
| | | | | | | | | | | | | | | | | | | We currently have a ppc_md member called cpu_irq_down, which disables IRQs for the cpu in question. The only caller of cpu_irq_down is the kexec code. On pSeries we need to do more than just teardown IRQs at kexec time, so rename the ppc_md member to kexec_cpu_down and expand it. The pSeries code needs to know, and other platforms might too, whether we're doing a crash shutdown (ie. panicking) or a regular kexec, so add a flag for that. The pSeries implementation of kexec_cpu_down does an unregister VPA call, which tells the Hypervisor to stop writing stuff into our pacas. Without this we can get weird memory corruption bugs when we kexec, caused by the Hypervisor writing into the first kernel's pacas which happens to be somewhere interesting in the second kernel's memory.

* [PATCH] powerpc: Merge vdso's and add vdso support to 32 bits kernelBenjamin Herrenschmidt2005-11-1117-1447/+1
| | | | | | | | | | | | | | | | | | | | | This patch moves the vdso's to arch/powerpc, adds support for the 32 bits vdso to the 32 bits kernel, rename systemcfg (finally !), and adds some new (still untested) routines to both vdso's: clock_gettime() with support for CLOCK_REALTIME and CLOCK_MONOTONIC, clock_getres() (same clocks) and get_tbfreq() for glibc to retreive the timebase frequency. Tom,Steve: The implementation of get_tbfreq() I've done for 32 bits returns a long long (r3, r4) not a long. This is such that if we ever add support for >4Ghz timebases on ppc32, the userland interface won't have to change. I have tested gettimeofday() using some glibc patches in both ppc32 and ppc64 kernels using 32 bits userland (I haven't had a chance to test a 64 bits userland yet, but the implementation didn't change and was tested earlier). I haven't tested yet the new functions. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [PATCH] powerpc: Move udbg code to arch/powerpcDavid Gibson2005-11-114-390/+0
| | | | | | | | | | | | | | | | | Since the udbg code in ppc64 has no ppc32 equivalent, move it straight over into arch/powerpc (and include/asm-powerpc for udbg.h). In time, we probably want to meld the various bits and pieces of 32-bit early debugging code into udbg, but for now only include it on CONFIG_PPC64=y builds. The only change during the move is to standardise the protecting #ifdef/#define in udbg.h, and move its banner comment above the initial #ifdef (which seems to be normal practice). Built and booted on POWER5 LPAR (ARCH=powerpc and ARCH=ppc64). Built for 32bit multiplatform (ARCH=powerpc).

* [PATCH] ppc64: Convert NUMA to sparsemem (3)Anton Blanchard2005-11-111-8/+3
| | | | | | | | | | | | | | | | Convert to sparsemem and remove all the discontigmem code in the process. This has a few advantages: - The old numa_memory_lookup_table can go away - All the arch specific discontigmem magic can go away We also remove the triple pass of memory properties and instead create a list of per node extents that we iterate through. A final cleanup would be to change our lmb code to store extents per node, then we can reuse that information in the numa code.

* [PATCH] ppc64: fix PCI IO mappingBenjamin Herrenschmidt2005-11-101-0/+3
| | | | | | | | | | | | | | | | | phbs_remap_io(), which maps the PCI IO space into the kernel virtual space, is called too early on powermac, and thus doesn't work. This fixes it by removing the call from all platforms and putting it back into the ppc64 common code where it belongs, after the actual probing of the bus. That means that before that call, only the ISA IO space (if any) is mapped, any PIO access (from quirks for example) will fail. This happens not to be a problem for now, but we'll have to rework that code if it becomes one in the future.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make some changes to the NEED_RESCHED and POLLING_NRFLAG to reduce confusion, and make their semantics rigid. Improves efficiency of resched_task and some cpu_idle routines. * In resched_task: - TIF_NEED_RESCHED is only cleared with the task's runqueue lock held, and as we hold it during resched_task, then there is no need for an atomic test and set there. The only other time this should be set is when the task's quantum expires, in the timer interrupt - this is protected against because the rq lock is irq-safe. - If TIF_NEED_RESCHED is set, then we don't need to do anything. It won't get unset until the task get's schedule()d off. - If we are running on the same CPU as the task we resched, then set TIF_NEED_RESCHED and no further action is required. - If we are running on another CPU, and TIF_POLLING_NRFLAG is *not* set after TIF_NEED_RESCHED has been set, then we need to send an IPI. Using these rules, we are able to remove the test and set operation in resched_task, and make clear the previously vague semantics of POLLING_NRFLAG. * In idle routines: - Enter cpu_idle with preempt disabled. When the need_resched() condition becomes true, explicitly call schedule(). This makes things a bit clearer (IMO), but haven't updated all architectures yet. - Many do a test and clear of TIF_NEED_RESCHED for some reason. According to the resched_task rules, this isn't needed (and actually breaks the assumption that TIF_NEED_RESCHED is only cleared with the runqueue lock held). So remove that. Generally one less locked memory op when switching to the idle thread. - Many idle routines clear TIF_POLLING_NRFLAG, and only set it in the inner most polling idle loops. The above resched_task semantics allow it to be set until before the last time need_resched() is checked before going into a halt requiring interrupt wakeup. Many idle routines simply never enter such a halt, and so POLLING_NRFLAG can be always left set, completely eliminating resched IPIs when rescheduling the idle task. POLLING_NRFLAG width can be increased, to reduce the chance of resched IPIs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Run idle threads with preempt disabled. Also corrected a bugs in arm26's cpu_idle (make it actually call schedule()). How did it ever work before? Might fix the CPU hotplugging hang which Nigel Cunningham noted. We think the bug hits if the idle thread is preempted after checking need_resched() and before going to sleep, then the CPU offlined. After calling stop_machine_run, the CPU eventually returns from preemption and into the idle thread and goes to sleep. The CPU will continue executing previous idle and have no chance to call play_dead. By disabling preemption until we are ready to explicitly schedule, this bug is fixed and the idle threads generally become more robust.

This seems to be done in other parts of the Kconfig file. Using those as an example, this should keep the MAX_ORDER block size at 16MB.

* [PATCH] ppc64: SMU partition recoveryBenjamin Herrenschmidt2005-11-081-4/+20
| | | | | | | | | | This patch adds the ability to the SMU driver to recover missing calibration partitions from the SMU chip itself. It also adds some dynamic mecanism to /proc/device-tree so that new properties are visible to userland.

| * [PATCH] Kprobes: Use RCU for (un)register synchronization - arch changesAnanth N Mavinakayanahalli2005-11-071-18/+6
| | | | | | | | | | | | | | | | | | | | | | | | Changes to the arch kprobes infrastructure to take advantage of the locking changes introduced by usage of RCU for synchronization. All handlers are now run without any locks held, so they have to be re-entrant or provide their own synchronization.
