* [POWERPC] check firmware state before suspendingDave C Boutcher2006-06-15
| | | | | | | | | | Currently the kernel blindly halts all the processors and calls the ibm,suspend-me rtas call. If the firmware is not in the correct state, we then re-start all the processors and return. It is much smarter to first check the firmware state, and only if it is waiting, call the ibm,suspend-me call. Signed-off-by: Paul Mackerras <paulus@samba.org>
* [POWERPC] Fix builtin command line interaction with firmwareAmos Waterland2006-06-15
| | | | | | | | | | | | | It seems that prom_init's early_cmdline_parse is broken on at least Apple 970 xserves and IBM JS20 blades with SLOF. The firmware of these machines returns -1 and 1 respectively when getprop is called for the bootargs property of /chosen, causing Linux to ignore its builtin command line in favor of a null string. This patch makes Linux use its builtin command line if getprop returns an error or a null string.

* [POWERPC] MSI abstractionJake Moilanen2006-06-15
| | | | | | | | | | | | | | | | Instead of trying to make PPC64 MSI fit in a Intel-centric MSI layer, a simple short-term solution is to hook the pci_{en/dis}able_msi() calls and make a machdep call. The rest of the MSI functions are superfluous for what is needed at this time. Many of which can have machdep calls added as needed. Ben and Michael Ellerman are looking into rewrite the MSI layer to be more generic. However, in the meantime this works as a interim solution.

* powerpc: Simplify push_end definition in pci_32.cPaul Mackerras2006-06-15
| | | | | | | | | | | The push_end macro in arch/powerpc/kernel/pci_32.c uses integer division and multiplication to achieve the effect of rounding a resource end address up and then advancing it to the end of a power-of-2 sized region. This changes it to an equivalent computation that only needs an integer add and OR. This is partly based on an earlier patch by Mel Gorman. Signed-off-by: Paul Mackerras <paulus@samba.org>
* powerpc: Use 64k pages without needing cache-inhibited large pagesPaul Mackerras2006-06-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some POWER5+ machines can do 64k hardware pages for normal memory but not for cache-inhibited pages. This patch lets us use 64k hardware pages for most user processes on such machines (assuming the kernel has been configured with CONFIG_PPC_64K_PAGES=y). User processes start out using 64k pages and get switched to 4k pages if they use any non-cacheable mappings. With this, we use 64k pages for the vmalloc region and 4k pages for the imalloc region. If anything creates a non-cacheable mapping in the vmalloc region, the vmalloc region will get switched to 4k pages. I don't know of any driver other than the DRM that would do this, though, and these machines don't have AGP. When a region gets switched from 64k pages to 4k pages, we do not have to clear out all the 64k HPTEs from the hash table immediately. We use the _PAGE_COMBO bit in the Linux PTE to indicate whether the page was hashed in as a 64k page or a set of 4k pages. If hash_page is trying to insert a 4k page for a Linux PTE and it sees that it has already been inserted as a 64k page, it first invalidates the 64k HPTE before inserting the 4k HPTE. The hash invalidation routines also use the _PAGE_COMBO bit, to determine whether to look for a 64k HPTE or a set of 4k HPTEs to remove. With those two changes, we can tolerate a mix of 4k and 64k HPTEs in the hash table, and they will all get removed when the address space is torn down.
