* move die notifier handling to common codeChristoph Hellwig2007-05-0844-153/+53
| | | | | | | | | | | | | | | | | | | | | | | This patch moves the die notifier handling to common code. Previous various architectures had exactly the same code for it. Note that the new code is compiled unconditionally, this should be understood as an appel to the other architecture maintainer to implement support for it aswell (aka sprinkling a notify_die or two in the proper place) arm had a notifiy_die that did something totally different, I renamed it to arm_notify_die as part of the patch and made it static to the file it's declared and used at. avr32 used to pass slightly less information through this interface and I brought it into line with the other architectures.

* Fixes and cleanups for earlyprintk aka boot consoleGerd Hoffmann2007-05-087-62/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The console subsystem already has an idea of a boot console, using the CON_BOOT flag. The implementation has some flaws though. The major problem is that presence of a boot console makes register_console() ignore any other console devices (unless explicitly specified on the kernel command line). This patch fixes the console selection code to *not* consider a boot console a full-featured one, so the first non-boot console registering will become the default console instead. This way the unregister call for the boot console in the register_console() function actually triggers and the handover from the boot console to the real console device works smoothly. Added a printk for the handover, so you know which console device the output goes to when the boot console stops printing messages. The disable_early_printk() call is obsolete with that patch, explicitly disabling the early console isn't needed any more as it works automagically with that patch. I've walked through the tree, dropped all disable_early_printk() instances found below arch/ and tagged the consoles with CON_BOOT if needed. The code is tested on x86, sh (thanks to Paul) and mips (thanks to Ralf). Changes to last version: Rediffed against -rc3, adapted to mips cleanups by Ralf, fixed "udbg-immortal" cmd line arg on powerpc.

* kconfig: centralize the selection of semaphore debugging in lib/Kconfig.debugRobert P. J. Day2007-05-082-9/+1
| | | | | | | | | | | | | | | | | | Remove the Kconfig selection of semaphore debugging from the ALPHA and FRV Kconfig files, and centralize it in lib/Kconfig.debug. There doesn't seem to be much point in letting individual architectures independently define the same Kconfig option when it can just as easily be put in a single Kconfig file and made dependent on a subset of architectures. that way, at least the option shows up in the same relative location in the menu each time.

| | | | | | | | | | | | | Convert over to the new NMI handling for getting IPMI watchdog timeouts via an NMI. This add config options to know if there is the ability to receive NMIs and if it has an NMI post processing call. Then it modifies the IPMI watchdog to take advantage of this so that it can know if an NMI comes in. It also adds testing that the IPMI NMI watchdog works.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Example memory map (from HP sx1000 with VGA enabled): 0x00000 - 0x9FFFF supports only WB (cacheable) access 0xA0000 - 0xBFFFF supports only UC (uncacheable) access 0xC0000 - 0xFFFFF supports only WB (cacheable) access Some versions of X map the entire 0x00000-0xFFFFF area at once. With the example above, this mmap must fail because there's no memory attribute that's safe for the entire area. Prior to this patch, we performed the mmap with a UC mapping. When X accessed the WB memory at 0xC0000, it caused an MCA. The crash can happen when mapping 0xC0000 from either /dev/mem or a /sys/.../legacy_mem file.

X uses reads the option ROM to initialize devices. A smaller test case is: # echo 1 > /sys/bus/pci/devices/0000:aa:03.0/rom # cp /sys/bus/pci/devices/0000:aa:03.0/rom x To avoid this, we can use the same ioremap_page_range() strategy that most architectures use for all ioremaps. These page table mappings come out of the vmalloc area. On ia64, these are in region 5 (0xA... addresses) and typically use 16KB or 64KB mappings instead of 16MB or 64MB mappings. The smaller mappings give more flexibility to use the correct attributes. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

This will free up one TLB entry for application, or even kernel if access pattern to per-cpu data area has high temporal locality. Since per-cpu is mapped at the top of region 7 address, we just need to add special case in alt_dtlb_miss. The physical address of per-cpu data is already conveniently stored in IA64_KR(PER_CPU_DATA). Latency for alt_dtlb_miss is not affected as we can hide all the latency. It was measured that alt_dtlb_miss handler has 23 cycles latency before and after the patch. The performance effect is massive for applications that put lots of tlb pressure on CPU. Workload environment like database online transaction processing or application uses tera-byte of memory would benefit the most. Measurement with industry standard database benchmark shown an upward of 1.6% gain. While smaller workloads like cpu, java also showing small improvement.

| | * | [IA64] remove per-cpu ia64_phys_stacked_size_p8Chen, Kenneth W2007-02-064-7/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's not efficient to use a per-cpu variable just to store how many physical stack register a cpu has. Ever since the incarnation of ia64 up till upcoming Montecito processor, that variable has "glued" to 96. Having a variable in memory means that the kernel is burning an extra cacheline access on every syscall and kernel exit path. Such "static" value is better served with the instruction patching utility exists today. Convert ia64_phys_stacked_size_p8 into dynamic insn patching. This also has a pleasant side effect of eliminating access to per-cpu area while psr.ic=0 in the kernel exit path. (fixable for per-cpu DTC work, but why bother?) There are some concerns with the default value that the instruc- tion encoded in the kernel image. It shouldn't be concerned. The reasons are: (1) cpu_init() is called at CPU initialization. In there, we find out physical stack register size from PAL and patch two instructions in kernel exit code. The code in question can not be executed before the patching is done. (2) current implementation stores zero in ia64_phys_stacked_size_p8, and that's what the current kernel exit path loads the value with. With the new code, it is equivalent that we store reg size 96 in ia64_phys_stacked_size_p8, thus creating a better safety net. Given (1) above can never fail, having (2) is just a bonus. All in all, this patch allow one less memory reference in the kernel exit path, thus reducing syscall and interrupt return latency; and avoid polluting potential useful data in the CPU cache.

Previously this was using the generic board, and lacked most of the peripheral support. Signed-off-by: Ryusuke Sakato <sakato.ryusuke@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously this was done in cpuinfo, but with the number of clocks growing, it makes more sense to place this in a different proc entry. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

This doesn't get a lot of use, however, and as akpm noted in the recent thread on l-k: http://lkml.org/lkml/2007/2/27/241 we're better off simply ripping it out and going the do_div() route if there happen to be any places that need it.
