2005-10-26[PATCH] ppc64: Fix wrong register mapping in mpic driverBenjamin Herrenschmidt
The mpic interrupt controller driver (used on G5 and early pSeries among others) has a bug where it doesn't get the right virtual address for the timer registers. It causes the driver to poke at the MMIO space of whatever has been mapped just next to it (ouch !) when initializing and causes boot failures on some IBM machines.

2005-10-21[PATCH] cpufreq: fix pending powernow timer stuck conditionDave Jones
AMD recently discovered that on some hardware, there is a race condition possible when a C-state change request goes onto the bus at the same time as a P-state change request. Both requests happen, but the southbridge hardware only acknowledges the C-state change. The PowerNow! driver is then stuck in a loop, waiting for the P-state change acknowledgement. The driver eventually times out, but can no longer perform P-state changes. It turns out the solution is to resend the P-state change, which the southbridge will acknowledge normally. Thanks to Johannes Winkelmann for reporting this and testing the fix.

2005-10-21[PATCH] ppc64: Fix typo bug in iSeries hash codeDavid Gibson
This fixes a stupid typo bug in the iSeries hash table code. When we place a hash PTE in the secondary bucket, instead of setting the SECONDARY flag bit, as we should, we (redundantly) set the VALID flag. This was introduced with the patch abolishing bitfields from the hash table code. Mea culpa, oops. It hasn't been noticed until now because in practice we don't hit the secondary bucket terribly often. Signed-off-by: David Gibson <dwg@au1.ibm.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-10-21[PATCH] ppc64: Fix pages marked dirty abusivelyBenjamin Herrenschmidt
While working on 64K pages, I found this little buglet in our update_mmu_cache() implementation. The code calls __hash_page() passing it an "access" parameter (the type of access that triggers the hash) containing the bits _PAGE_RW and _PAGE_USER of the linux PTE. The latter is useless in this case and the former is wrong. In fact, if we have a writeable PTE and we pass _PAGE_RW to hash_page(), it will set _PAGE_DIRTY (since we track dirty that way, by hash faulting !dirty) which is not what we want. In fact, the correct fix is to always pass 0. That means that only read-only or already dirty read write PTEs will be preloaded. The (hopefully rare) case of a non dirty read write PTE can't be preloaded this way, it will have to fault in hash_page on the actual access.

2005-10-19[PATCH] swiotlb: make sure initial DMA allocations really are in DMA memoryYasunori Goto
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.

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.

2005-10-12[SPARC64]: Fix boot failures on SunBlade-150David S. Miller
The sequence to move over to the Linux trap tables from the firmware ones needs to be more air tight. 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>

2005-10-12[PATCH] ppc32: Tell userland about lack of standard TBBenjamin Herrenschmidt
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).
