2006-01-09[PATCH] ppc32: Put cache flush routines back into .relocate_code sectionPaul Janzen
In 2.6.14, we had the following definition of _GLOBAL() in include/asm-ppc/processor.h: #define _GLOBAL(n)\ .stabs __stringify(n:F-1),N_FUN,0,0,n;\ .globl n;\ n: In 2.6.15, as part of the great powerpc merge, we moved this definition to include/asm-powerpc/ppc_asm.h, where it appears (to 32-bit code) as: #define _GLOBAL(n) \ .text; \ .stabs __stringify(n:F-1),N_FUN,0,0,n;\ .globl n; \ n: Mostly, this is fine. However, we also have the following, in arch/ppc/boot/common/util.S: .section ".relocate_code","xa" [...] _GLOBAL(flush_instruction_cache) [...] _GLOBAL(flush_data_cache) [...] The addition of the .text section definition in the definition of _GLOBAL overrides the .relocate_code section definition. As a result, these two functions don't end up in .relocate_code, so they don't get relocated correctly, and the boot fails. There's another suspicious-looking usage at kernel/swsusp.S:37 that someone should look into. I did not exhaustively search the source tree, though. The following is the minimal patch that fixes the immediate problem. I could easily be convinced that the _GLOBAL definition should be modified to remove the ".text;" line either instead of, or in addition to, this fix.

This makes ARCH=ppc build in your powerpc tree again, with the new syscall entry/exit path. Still doesn't actually boot on my Pegasos; the last thing I see is 'MMU:exit'. But at least it builds -- I'll look at why it doesn't boot later, so that I can see if the mv643xx_eth actually works with ARCH=ppc (it doesn't with ARCH=powerpc; two in every three packets I receive are offset by 4 bytes).

2006-01-09[PATCH] ppc32: m8xx watchdog updateMarcelo Tosatti
This updates m8xx_wdt as follows: 1) Remove now obsolete fpos check in the write() function. The driver is currently non functional due to this bug. 2) Use in/out macros for register access. 3) Allows m8xx_wdt to use a kernel timer instead of the builtin RTC/PIT for keep-alive trigger (which is responsible for servicing the watchdog until an userspace application takes over). For instance Cyclades PRxK boards (MPC 855T based) have a non-functional internal RTC/PIT unit. Behaviour for boards with RTC/PIT is unchaged. 4) The last change required moving the RTCSC register setting code to a weak function which can be overriden by board specific files. Otherwise the timer init code trashes the register making it impossible for m8xx_wdt to detect the situation.

2006-01-09[PATCH] powerpc: Unify udbg (#2)Benjamin Herrenschmidt
This patch unifies udbg for both ppc32 and ppc64 when building the merged achitecture. xmon now has a single "back end". The powermac udbg stuff gets enriched with some ADB capabilities and btext output. In addition, the early_init callback is now called on ppc32 as well, approx. in the same order as ppc64 regarding device-tree manipulations. The init sequences of ppc32 and ppc64 are getting closer, I'll unify them in a later patch. For now, you can force udbg to the scc using "sccdbg" or to btext using "btextdbg" on powermacs. I'll implement a cleaner way of forcing udbg output to something else than the autodetected OF output device in a later patch.

2006-01-09[PATCH] powerpc: serial port discovery (#2)Benjamin Herrenschmidt
This moves the discovery of legacy serial ports to a separate file, makes it common to ppc32 and ppc64, and reworks it to use the new OF address translators to get to the ports early. This new version can also detect some PCI serial cards using legacy chips and will probably match those discovered port with the default console choice. Only ppc64 gets udbg still yet, unifying udbg isn't finished yet. It also adds some speed-probing code to udbg so that the default console can come up at the same speed it was set to by the firmware.

2006-01-09[PATCH] spufs: The SPU file system, baseArnd Bergmann
This is the current version of the spu file system, used for driving SPEs on the Cell Broadband Engine. This release is almost identical to the version for the 2.6.14 kernel posted earlier, which is available as part of the Cell BE Linux distribution from http://www.bsc.es/projects/deepcomputing/linuxoncell/. The first patch provides all the interfaces for running spu application, but does not have any support for debugging SPU tasks or for scheduling. Both these functionalities are added in the subsequent patches. See Documentation/filesystems/spufs.txt on how to use spufs.

2006-01-09[PATCH] powerpc: Merge kexecMichael Ellerman
This patch merges, to some extent, the PPC32 and PPC64 kexec implementations. We adopt the PPC32 approach of having ppc_md callbacks for the kexec functions. The current PPC64 implementation becomes the "default" implementation for PPC64 which platforms can select if they need no special treatment. I've added these default callbacks to pseries/maple/cell/powermac, this means iSeries no longer supports kexec - but it never worked anyway. I've renamed PPC32's machine_kexec_simple to default_machine_kexec, inline with PPC64. Judging by the comments it might be better named machine_kexec_non_of, or something, but at the moment it's the only implementation for PPC32 so it's the "default". Kexec requires machine_shutdown(), which is in machine_kexec.c on PPC32, but we already have in setup-common.c on powerpc. All this does is call ppc_md.nvram_sync, which only powermac implements, so instead make machine_shutdown a ppc_md member and have it call core99_nvram_sync directly on powermac. I've also stuck relocate_kernel.S into misc_32.S for powerpc. Built for ARCH=ppc, and 32 & 64 bit ARCH=powerpc, with KEXEC=y/n. Booted on P5 LPAR and successfully kexec'ed.

2005-12-05ppc: Build in all three of powermac, PREP and CHRP supportPaul Mackerras
This reverts commit da0825fd201a03294dbf7f8f030676d608da122c, making it so that if you select CONFIG_PPC_MULTIPLATFORM you get support for PMAC, PREP and CHRP built in. The reason for not allowing PMAC, PREP and CHRP to be selected individually for ARCH=ppc is that there is too much interdependency between them in the platform support code. For example, CHRP uses the PMAC nvram code. Configuring with ARCH=powerpc does allow you to select support for PMAC and CHRP separately. Support for PREP is not there yet but should be there soon.

2005-11-16[PATCH] ppc32 8xx: update_mmu_cache() needs unconditional tlbieMarcelo Tosatti
Currently 8xx fails to boot due to endless pagefaults. Seems the bug is exposed by the change which avoids flushing the TLB when not necessary (in case the pte has not changed), introduced recently: __handle_mm_fault(): entry = pte_mkyoung(entry); if (!pte_same(old_entry, entry)) { ptep_set_access_flags(vma, address, pte, entry, write_access); update_mmu_cache(vma, address, entry); lazy_mmu_prot_update(entry); } else { /* * This is needed only for protection faults but the arch code * is not yet telling us if this is a protection fault or not. * This still avoids useless tlb flushes for .text page faults * with threads. */ if (write_access) flush_tlb_page(vma, address); } The "update_mmu_cache()" call was unconditional before, which caused the TLB to be flushed by: if (pfn_valid(pfn)) { struct page *page = pfn_to_page(pfn); if (!PageReserved(page) && !test_bit(PG_arch_1, &page->flags)) { if (vma->vm_mm == current->active_mm) { #ifdef CONFIG_8xx /* On 8xx, cache control instructions (particularly * "dcbst" from flush_dcache_icache) fault as write * operation if there is an unpopulated TLB entry * for the address in question. To workaround that, * we invalidate the TLB here, thus avoiding dcbst * misbehaviour. */ _tlbie(address); #endif __flush_dcache_icache((void *) address); } else flush_dcache_icache_page(page); set_bit(PG_arch_1, &page->flags); } Which worked to due to pure luck: PG_arch_1 was always unset before, but now it isnt. The root of the problem are the changes against the 8xx TLB handlers introduced during v2.6. What happens is the TLBMiss handlers load the zeroed pte into the TLB, causing the TLBError handler to be invoked (thats two TLB faults per pagefault), which then jumps to the generic MM code to setup the pte. The bug is that the zeroed TLB is not invalidated (the same reason for the "dcbst" misbehaviour), resulting in infinite TLBError faults. The "two exception" approach requires a TLB flush (to nuke the zeroed TLB) at each PTE update for correct behaviour: Signed-off-by: Marcelo Tosatti <marcelo.tosatti@cyclades.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
