2006-05-09[PATCH] ppc32/8xx: Fix r3 trashing due to 8MB TLB page instantiationMarcelo Tosatti
Instantiation of 8MB pages on the TLB cache for the kernel static mapping trashes r3 register on !CONFIG_8xx_CPU6 configurations. This ensures r3 gets saved and restored. Signed-off-by: Marcelo Tosatti <marcelo@kvack.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-02-10[PATCH] powerpc: trivial: modify comments to refer to new location of filesJon Mason
This patch removes all self references and fixes references to files in the now defunct arch/ppc64 tree. I think this accomplises everything wanted, though there might be a few references I missed. Signed-off-by: Jon Mason <jdmason@us.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-02-07[PATCH] powerpc/8xx: last two 8MB D-TLB entries are incorrectly setMarcelo Tosatti
The last two 8MB TLB entries are being incorrectly set by initial_mmu on 8xx. The first entry is written with the same virtual/physical address, which renders it invalid: BDI>rms 792 0x00001e00 BDI>rms 824 1 BDI>rds 824 SPR 824 : 0xc08000c0 -1065353024 BDI>rds 825 SPR 825 : 0xc0800de0 -1065349664 BDI>rds 826 SPR 826 : 0x00000000 0 And the second entry, in addition, does not have its TLB index set correctly.

2006-01-14[PATCH] powerpc/8xx: Use 8MB D-TLB's for kernel static mapping faultsMarcelo Tosatti
The following implements support for instantiation of 8MB D-TLB entries for the kernel direct virtual mapping on 8xx, thus reducing TLB space consumed for the kernel. Test used: writing 40MB from /dev/zero to file in ext2fs over RAMDISK. $ time dd if=/dev/zero of=file bs=4k count=10000 VANILLA 8MB kernel data pages real 0m11.485s real 0m11.267s user 0m0.218s user 0m0.250s sys 0m8.939s sys 0m9.108s real 0m11.518s real 0m10.978s user 0m0.203s user 0m0.222s sys 0m9.585s sys 0m9.138s real 0m11.554s real 0m10.967s user 0m0.228s user 0m0.222s sys 0m9.497s sys 0m9.127s real 0m11.633s real 0m11.286s user 0m0.214s user 0m0.196s sys 0m9.529s sys 0m9.134s and averages for both: real 11.54750 real 11.12450 Which is a 3.6% improvement in execution time. More improvement is expected for loads with larger kernel data footprint (real workloads).

2005-10-01powerpc: merge idle_power4.S and trapc.sStephen Rothwell
Use idle_power4.S from ppc64 as we are not going to support 32 bit power4 in the merged tree. Merge ppc64 traps.c into powerpc traps.c: use ppc64 versions of exception routine names (as they don't have StudlyCaps) make all the versions if die() have the same prototype Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>

2005-07-27[PATCH] ppc32: 8xx: update DataTLBMiss exception commentMarcelo Tosatti
On PPC 8xx, the DataTLBMiss handler does not jump directly to the page fault handler, as was the case in v2.4. It instead loads an invalid TLB which causes a subsequent DataTLBError exception. The comment on top of it haven't been update to reflect the change, though.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
