| 2007-05-26 | If booted from ADPT,2940U2B, root is on scsi. | Dale Rahn | |
| 2007-05-26 | More comment typos from Diego Casati. Including winners like funtion, allmost, | Kenneth R Westerback | |
| oustside, seqencer, toghether, nessissary, etc. | |||
| 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 | |
| miod@ ok | |||
| 2007-05-25 | Unifdef TLB_TRACE and TLBTRACE, no functional change. | Miod Vallat | |
| 2007-05-25 | "boundries" -> "boundaries" in various comments. Started by Diego Casati. | Kenneth R Westerback | |
| 2007-05-25 | 'Proto type' -> 'Prototype' when discussing functions in comments. | Kenneth R Westerback | |
| Inspired by similar diffs from Diego Casati in other files. | |||
| 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). | |||
| 2007-05-25 | rename cpu_dumpconf() to dumpconf(); no need to be different from other ↵ | Theo de Raadt | |
| architectures | |||
| 2007-05-23 | Add code to spin up secondary cpu's; still work in progress. | Mark Kettenis | |
| prompted by deraadt@ a few times already. | |||
| 2007-05-23 | Print real/available memory in MB as well as bytes in dmesg, and unify | Peter Valchev | |
| architectures to print it the same way. ok henning, miod; i386 part from tom | |||
| 2007-05-23 | Add hack to prevent switching to serial console on four-digit B/C/J class | Mark Kettenis | |
| workstations. This makes these machines actually boot. ok miod@ | |||
| 2007-05-23 | Enable elroy(4). | Mark Kettenis | |
| 2007-05-23 | Add proper bus_space_vaddr() implementation. | Mark Kettenis | |
| ok miod@ | |||
| 2007-05-23 | timecounter support (e.g. soekris net4501); ok grange@ | Markus Friedl | |
| 2007-05-22 | Add pciide(4) and things that attach to it. | Mark Kettenis | |
| 2007-05-22 | Add elory(4). | Mark Kettenis | |
| 2007-05-22 | Add option HP8700_CPU. | Mark Kettenis | |
| 2007-05-22 | Hook up astro(4). | Mark Kettenis | |
| 2007-05-22 | protect more variables from existing outside of locore, should fix | Martin Reindl | |
| cpuinfo breakage (but my make build is still running) ok gwk@ | |||
| 2007-05-22 | enable uts(4) - USB touchscreen support | Robert Nagy | |
| 2007-05-21 | Add support for 8700/pcxw2 cpu. | Mark Kettenis | |
| 2007-05-21 | Ask firmware for reset before trying ourselves; needed for four-digit b/c/j | Mark Kettenis | |
| workstations. tested by otto@, krw@; ok deraadt@ | |||
| 2007-05-21 | Import code to support the Elroy chip from hppa64 and make it actually work. | Mark Kettenis | |
| Still a bit of a hack, but it makes the onboard devices work. | |||
| 2007-05-21 | Implement deep interrupt swizzling by mapping all four PCI interrupt pins | Mark Kettenis | |
| for PCI-PCI bridges and passing the mapping to the attached bus device. MD code can use these when mapping PCI device interrupts. This diff adds such code for amd64 and i386. This fixes interrupt mapping for devices that sit behind two PCI-PCI bridges where the firmware only provides a mapping for the first PCI-PCI bridge. tested by sturm@, krw@, and a few others, ok deraadt@ | |||
| 2007-05-21 | Make iommu_dvmamap_unload cleanup properly. | Mark Kettenis | |
| 2007-05-21 | Add msk(4). | Mark Kettenis | |
| 2007-05-21 | Initial stab at a driver for the Astro chip. Mostly IOMMU code to handle | Mark Kettenis | |
| coherent DMA. | |||
| 2007-05-21 | timecounters for armish. | Dale Rahn | |
| 2007-05-21 | Switch pcfiic to rwlock. | Jonathan Gray | |
| ok dlg@ kettenis@ | |||
| 2007-05-20 | lockmgr -> rwlock for piic(4), kiic(4) and smu(4); | Thordur I. Bjornsson | |
| smu(4) tested by kettenis@, ok krw@ | |||
| 2007-05-20 | Fix KERNBASE, so that profiling kernels initialize (but profiling is broken | Miod Vallat | |
| at the moment). | |||
| 2007-05-20 | Since we no longer use 3 bits but the whole 7 to get the processor revision | Miod Vallat | |
| number, we should test for 10, not 2, as the revision for which the xxx.usr errata applies; also, going through the errata, revision 2/10 (1010x) _is_ affected. | |||
| 2007-05-20 | On AV-class machines, SCSI interrupts still come from VIA2, not PSC, so | Miod Vallat | |
| IPL_BIO should not be modified. Found the hard way by martin@ | |||
| 2007-05-20 | Replace ASSERT with KDASSERT and get rid of its definition; while there, | Miod Vallat | |
| remove some #if 0 dead code which won't get ressurrected anytime soon. | |||
| 2007-05-20 | Remove unused badaddr(). | Miod Vallat | |
| 2007-05-20 | Remove irrelevant code and defines. | Miod Vallat | |
| 2007-05-20 | Check for codec presence in match(), and don't attach if none is found. | Miod Vallat | |
| ok kettenis@ | |||
| 2007-05-20 | addess -> address | Miod Vallat | |
| 2007-05-20 | option AHC_CTRL_ID is not used. | Miod Vallat | |
| 2007-05-19 | Add some phy's found on certain xl(4) models. From brad at comstyle dot com. | Mark Kettenis | |
| 2007-05-19 | Uncomment em(4) entry. From brad at comstyle dot com. | Mark Kettenis | |
| 2007-05-19 | Oops, get the ``disabling cpu'' message correct. | Miod Vallat | |
| 2007-05-19 | Silence a diagnostic message in multiprocessor kernels, it makes things worse. | Miod Vallat | |
| 2007-05-19 | Send an IPI in signotify() if the process runs on a different processor, | Miod Vallat | |
| similar to the fix which went into i386 and amd64 a few weeks ago. | |||
| 2007-05-19 | Force other processors to spin when one is in ddb. | Miod Vallat | |
| 2007-05-19 | (disabled) option for PCIAGP. at least lets i945 chipsets work | Ted Unangst | |
| ok dim | |||
