* [PATCH] spufs: Disable local interrupts for SPE hash_page calls.Arnd Bergmann2006-04-29
| | | | | | | | | | | | | This patch disables and saves local interrupts during hash_page processing for SPE contexts. We have to do it explicitly in the spu_irq_class_1_bottom function. For the interrupt handlers, we get the behaviour implicitly by using SA_INTERRUPT to disable interrupts while in the handler.

* [PATCH] powerpc: Add cputable entry for POWER6Anton Blanchard2006-04-28
| | | | | | | | | | | | Add a cputable entry for the POWER6 processor. The SIHV and SIPR bits in the mmcra have moved in POWER6, so disable support for that until oprofile is fixed.

| | | | | | | | | | | Wire up *at syscalls. This patch has been tested on ppc64 (using glibc's testsuite, both 32bit and 64bit), and compile-tested for ppc32 (I have currently no ppc32 system available, but I expect no problems).

* [PATCH] powerpc: Use check_legacy_ioport() on ppc32 too.David Woodhouse2006-04-28
| | | | | | | | | | | | | Some people report that we die on some Macs when we are expecting to catch machine checks after poking at some random I/O address. I'd seen it happen on my dual G4 with serial ports until we fixed those to use OF, but now other users are reporting it with i8042. This expands the use of check_legacy_ioport() to avoid that situation even on 32-bit kernels. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
* [PATCH] powerpc64: Fix loading of modules without a .toc sectionAlan Modra2006-04-28
| | | | | | | | | | | | | | Normally, ppc64 module .ko files contain a table-of-contents (.toc) section, but if the module doesn't reference any static or external data or external procedures, it is possible for gcc/binutils to generate a .ko that doesn't have a .toc. Currently the module loader refuses to load such a module, since it needs the address of the .toc section to use in relocations. This patch fixes the problem by using the address of the .stubs section instead, which is an acceptable substitute in this situation. Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc/pseries: Tell firmware our capabilities on new machinesPaul Mackerras2006-04-28
| | | | | | | | | This adds code to call a new firmware method to tell the firmware what machines and capabilities (such as VMX/Altivec) we support.

* [PATCH] powerpc: Fix pagetable bloat for hugepagesDavid Gibson2006-04-28
| | | | | | | | | | | | | | | | | At present, ARCH=powerpc kernels can waste considerable space in pagetables when making large hugepage mappings. Hugepage PTEs go in PMD pages, but each PMD page maps 256M and so contains only 16 hugepage PTEs (128 bytes of data), but takes up a 1024 byte allocation. With CONFIG_PPC_64K_PAGES enabled (64k base page size), the situation is worse. Now hugepage PTEs are at the PTE page level (also mapping 256M), so we store 16 hugepage PTEs in a 64k allocation. The PowerPC MMU already means that any 256M region is either all hugepage, or all normal pages. Thus, with some care, we can use a different allocation for the hugepage PTE tables and only allocate the 128 bytes necessary. Signed-off-by: Paul Mackerras <paulus@samba.org>

* [PATCH] Remove __devinit and __cpuinit from notifier_call definitionsChandra Seetharaman2006-04-26
| | | | | | | | | | | | | Few of the notifier_chain_register() callers use __init in the definition of notifier_call.

| | | | | | | | | | | | | | | | Few of the notifier_chain_register() callers use __devinitdata in the definition of notifier_block data structure. It is incorrect as the data structure should be available after the initializations (they do not unregister them during initializations).

* [PATCH] Add support for the sys_vmsplice syscallJens Axboe2006-04-26
| | | | | | | | | | | sys_splice() moves data to/from pipes with a file input/output. sys_vmsplice() moves data to a pipe, with the input being a user address range instead. This uses an approach suggested by Linus, where we can hold partial ranges inside the pages[] map. Hopefully this will be useful for network receive support as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Turn on the DART already at 1GB. This is needed because of crippled devices in some systems, i.e. Airport Extreme cards, only supporting 30-bit DMA addresses. Otherwise, users with between 1 and 2GB of memory will need to manually enable it with iommu=force, and that's no good. Some simple performance tests show that there's a slight impact of enabling DART, but it's in the 1-3% range (kernel build with disk I/O as well as over NFS). iommu=off can still be used for those who don't want to deal with the overhead (and don't need it for any devices).

| * | | powerpc: Use correct sequence for putting CPU into nap modePaul Mackerras2006-04-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We weren't using the recommended sequence for putting the CPU into nap mode. When I changed the idle loop, for some reason 7447A cpus started hanging when we put them into nap mode. Changing to the recommended sequence fixes that. The complexity here is that the recommended sequence is a loop that keeps putting the cpu back into nap mode. Clearly we need some way to break out of the loop when an interrupt (external interrupt, decrementer, performance monitor) occurs. Here we use a bit in the thread_info struct to indicate that we need this, and the exception entry code notices this and arranges for the exception to return to the value in the link register, thus breaking out of the loop. We use a new `local_flags' field in the thread_info which we can alter without needing to use an atomic update sequence. The PPC970 has the same recommended sequence, so we do the same thing there too. This also fixes a bug in the kernel stack overflow handling code on 32-bit, since it was causing a value that we needed in a register to get trashed. Signed-off-by: Paul Mackerras <paulus@samba.org>

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current implementations define NODES_SHIFT in include/asm-xxx/numnodes.h for each arch. Its definition is sometimes configurable. Indeed, ia64 defines 5 NODES_SHIFT values in the current git tree. But it looks a bit messy. SGI-SN2(ia64) system requires 1024 nodes, and the number of nodes already has been changeable by config. Suitable node's number may be changed in the future even if it is other architecture. So, I wrote configurable node's number. This patch set defines just default value for each arch which needs multi nodes except ia64. But, it is easy to change to configurable if necessary. On ia64 the number of nodes can be already configured in generic ia64 and SN2 config. But, NODES_SHIFT is defined for DIG64 and HP'S machine too. So, I changed it so that all platforms can be configured via CONFIG_NODES_SHIFT. It would be simpler.

In case someone gets a sense of deja-vu, part of this was submitted last Sep, I thought the changes went in, but either got backed out, or just got lost. First, change the local_buffer declaration to be unsigned char *. We had a bad-math problem in a 2.4 tree which was built with a "-fsigned-char" parm. I dont believe we ever build with that parm now-a-days, but to be safe, I'd prefer the declaration be explicit. Second, fix a bad math calculation for splpar_strlen. Third, on the rtas_call for get-system-parameter, pass in RTAS_DATA_BUF_SIZE for the rtas_data_buf size, instead of letting random data determine the size. Until recently, we've had a sufficiently large 'random data' value get passed in, so the function just happens to have worked OK. Now it's getting passed a '0', which causes the rtas_call to return success, but no data shows up in the buffer. (oops!). This was found by the LTC test org. This is in a branch of code that only gets run on SPLPAR systems. Tested on power5 Lpar. Signed-off-by: Will Schmidt <willschm@us.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

I've made the patch against the linux-2.6 git tree and Segher's patch: [PATCH] Change H_StudlyCaps to H_SHOUTING_CAPS We moved this into the common powerpc code based on comments we got after posting the first eHCA InfiniBand device driver patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The current code prints an ambiguous message if the recovery of a failed PCI device fails. Give this special case its own unique message. Signed-off-by: Linas Vepstas <linas@austin.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
* | | [PATCH] powerpc/pseries: mutex lock to serialize EEH event processingLinas Vepstas2006-04-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This forces the processing of EEH PCI events to be serialized, using a very simple mutex lock. This serialization is required to avoid races involving additional PCI device failures that may occur during the recovery phase of a previous failure.

| * | powerpc: converted embedded platforms to use new define_machine supportKumar Gala2006-03-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Removed platform_init usage on 83xx and 85xx and use define_machine and probe(). For now we always return true in the problem since you can only build for one specific board at a time. This is an artificial constraint. When we get ride of it we will need to update the Kconfig's for these sub-arch's and make the board's probe() functions actually do something. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
