* [ARM] 3027/1: BAST - reduce NAND timings slightlyBen Dooks2005-10-20
| | | | | | | | | | | | Patch from Ben Dooks The current Simtec BAST nand area timings are a little too slow to be obtained by a 2410 running at 266MHz, so reduce the timings slightly to bring them into the acceptable range.

* | [PATCH] swiotlb: make sure initial DMA allocations really are in DMA memoryYasunori Goto2005-10-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This introduces a limit parameter to the core bootmem allocator; The new parameter indicates that physical memory allocated by the bootmem allocator should be within the requested limit. We also introduce alloc_bootmem_low_pages_limit, alloc_bootmem_node_limit, alloc_bootmem_low_pages_node_limit apis, but alloc_bootmem_low_pages_limit is the only api used for swiotlb. The existing alloc_bootmem_low_pages() api could instead have been changed and made to pass right limit to the core allocator. But that would make the patch more intrusive for 2.6.14, as other arches use alloc_bootmem_low_pages(). We may be done that post 2.6.14 as a cleanup. With this, swiotlb gets memory within 4G for both x86_64 and ia64 arches.

| * [SPARC64]: Fix powering off on SMP.David S. Miller2005-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Doing a "SUNW,stop-self" firmware call on the other cpus is not the correct thing to do when dropping into the firmware for a halt, reboot, or power-off. For now, just do nothing to quiet the other cpus, as the system should be quiescent enough. Later we may decide to implement smp_send_stop() like the other SMP platforms do.

* | [SPARC64]: Fix boot failures on SunBlade-150David S. Miller2005-10-12

It turns out that to be %100 safe we do need to be able to translate OBP mappings in our TLB miss handlers early. In order not to eat up a lot of kernel image memory with static page tables, just use the translations array in the OBP TLB miss handlers. That solves the bulk of the problem. Furthermore, to make sure the OBP TLB miss path will work even before the fixed MMU globals are loaded, explicitly load %g1 to TLB_SFSR at the beginning of the i-TLB and d-TLB miss handlers. To ease the OBP TLB miss walking of the prom_trans[] array, we sort it then delete all of the non-OBP entries in there (for example, there are entries for the kernel image itself which we're not interested in at all). We also save about 32K of kernel image size with this change. Not a bad side effect :-) There are still some reasons why trampoline.S can't use the setup_trap_table() yet. The most noteworthy are: 1) OBP boots secondary processors with non-bias'd stack for some reason. This is easily fixed by using a small bootup stack in the kernel image explicitly for this purpose. 2) Doing a firmware call via the normal C call prom_set_trap_table() goes through the whole OBP enter/exit sequence that saves and restores OBP and Linux kernel state in the MMUs. This path unfortunately does a "flush %g6" while loading up the OBP locked TLB entries for the firmware call. If we setup the %g6 in the trampoline.S code properly, that is in the PAGE_OFFSET linear mapping, but we're not on the kernel trap table yet so those addresses won't translate properly. One idea is to do a by-hand firmware call like we do in the early bootup code and elsewhere here in trampoline.S But this fails as well, as aparently the secondary processors are not booted with OBP's special locked TLB entries loaded. These are necessary for the firwmare to processes TLB misses correctly up until the point where we take over the trap table. This does need to be resolved at some point. Signed-off-by: David S. Miller <davem@davemloft.net>
* | [PATCH] ppc32: Tell userland about lack of standard TBBenjamin Herrenschmidt2005-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Glibc is about to get some new high precision timer stuff that relies on the standard timebase of the PPC architecture. However, some (rare & old) CPUs do not have such timebase and it is a bit annoying to have your stuff just crash because you are running on the wrong CPU... This exposes to userland a CPU feature bit that tells that the current processor doesn't have a standard timebase. It's negative logic so that glibc will still "just work" on older kernels (it will just be unhappy on those old CPUs but that doesn't really matter as distro tend to update glibc & kernel at the same time).

Previously we would do the following: 1) Disable PSTATE_IE in %pstate. 2) Set %tba by hand to sparc64_ttable_tl0 3) Initialize alternate, mmu, and interrupt global trap registers. 4) Call prom_set_traptable() That doesn't work very well actually with the way we boot the kernel VM these days. It worked by luck on many systems because the firmware accesses for the prom_set_traptable() call happened to be loaded into the TLB already, something we cannot assume. So the new scheme is this: 1) Clear PSTATE_IE in %pstate and set %pil to 15 2) Call prom_set_traptable() 3) Initialize alternate, mmu, and interrupt global trap registers. and this works quite well. This sequence has been moved into a callable function in assembler named setup-trap_table(). The idea is that eventually trampoline.S can use this code as well. That isn't possible currently due to some complications, but eventually we should be able to do it. Thanks to Meelis Roos for the Ultra5 boot failure report. Signed-off-by: David S.

* | [PATCH] x86_64: Fix change_page_attr cache flushingAndi Kleen2005-10-10
|/ | | | | | | | | | | Noticed by Terence Ripperda Undo wrong change in global_flush_tlb. We need to flush the caches in all cases, not just when pages were reverted. This was a bogus optimization added earlier, but it was wrong. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
