| 2007-05-28 | Move the MSIZE, MCLSHIFT, MCLBYTES and the MCLOFSET | Thordur I. Bjornsson | |
| mbuf constants from MD param.h to MI param.h. Besides being the same on every arch, things will most probly break if any arch has different values then the others. The NMBCLUSTERS constants needs to be MD though; ok miod@,krw@,claudio@ | |||
| 2007-05-28 | Flush pmap from tlb before freeing it. Makes Core2Duo boxes more | Kenneth R Westerback | |

| 2007-05-27 | be more agressive on invalidation; perform invalidates on load* and unload | Jason Wright | |
| 2007-05-27 | Locore UP can use the same code as MULTIPROCESSOR to access the GDT | Tom Cosgrove | |
| once we're up and running; similar to what was just committed for machdep.c and pmap.c. ok art@ deraadt@ | |||
| 2007-05-27 | We don't need to special-case access to the GDT for UP or MP, since | Tom Cosgrove | |
| ci_gdt is set correctly even when ! MULTIPROCESSOR. ok art@ toby@ | |||

| 2007-05-27 | Use the direct maps (cached on uncached) for bus_space mappings. | Artur Grabowski | |
| jason@ ok | |||
| 2007-05-27 | - Redo the way we set up the direct map. Map the first 4GB of it | Artur Grabowski | |
| in locore so that we can use the direct map in pmap_bootstrap when setting up the initial page tables. - Introduce a second direct map (I love large address spaces) with uncached pages. jason@ ok | |||

| 2007-05-27 | When deciding whether to allocate a bounce buffer, we need one if | Tom Cosgrove | |
| we are going to read exactly at 1 MB (i.e. fix an off-by-one that is already correct in the amd64 version of this file). ok toby@ | |||

| 2007-05-25 | "interupt" -> "interrupt" in various comments. Mostly from Diego Casati. | Kenneth R Westerback | |
| 2007-05-25 | Edge cases can trigger a TLB miss exception instead of an invalid TLB | Miod Vallat | |
| exception on early R5000 revisions. Despite this bug being supposedly fixed in R5000 revision 2 onwards, it nevertheless occurs quite frequently on matthieu's revision 2.1 R5000. Servicing the TLB miss exception would cause a duplicate TLB to be inserted, which causes the processor operation to become unpredictable (but lethal to the kernel, ten times out of nine). More details about the problem can be found in: http://www.linux-mips.org/archives/linux-mips/2000-02/msg00040.html We work around the issue by checking for an existing TLB entry, and handling this as an invalid TLB exception (as it was intended to be), in this case. Unfortunately this causes a measurable 1% slowdown on ``safe'' processors, so we'll work on providing different tlb handler flavours in the near future to recover from this. | |||
| 2007-05-25 | Define rw_cas. Trivially simple on amd64 with atomic_cas_ul. | Artur Grabowski | |

| 2007-05-25 | Comment typos and tidying. From Diego Casati. | Kenneth R Westerback | |
| 2007-05-25 | Change the old slow and complicated TLB shootdown code to new, fast and | Artur Grabowski | |
| simple. This is basically the same code as on i386 and basically the same performance improvements. This change also includes code to delay the freeing of ptps until they have been properly shot. in snaps for a week, no problems reported. | |||
| 2007-05-25 | Replace the overdesigned and overcomplicated tlb shootdown code with | Artur Grabowski | |
| very simple and dumb fast tlb IPI handlers that have in the order of the same amount of instructions as the old code had function calls. All TLB shootdowns are reorganized so that we always shoot the, without looking at PG_U and when we're shooting a range (primarily in pmap_remove), we shoot the range when there are 32 or less pages in it, otherwise we just nuke the whole TLB (this might need tweaking if someone is interested in micro-optimization). The IPIs are not handled through the normal interrupt vectoring code, they are not blockable and they only shoot one page or a range of pages or the whole tlb. This gives a 15% reduction in system time on my dual-core laptop during a kernel compile and an 18% reduction in real time on a quad machine doing bulk ports build. Tested by many, in snaps for a week, no slowdowns reported (although not everyone is seeing such huge wins). | |||
