2006-10-14ACPI: SCI interrupt source overrideKimball Murray1-5/+5
The Linux group at Stratus Technologies has come across an issue with SCI routing under ACPI. We were bitten by this when we made an x86_64 platform whose BIOS provides an Interrupt Source Override for the SCI itself. Apparently the override has no effect for the System Control Interrupt, and this appears to be because of the way the SCI is setup in the ACPI code. It does not handle the case where busirq != gsi. The code that sets up the SCI routing assumes that bus irq == global irq. So there is simply no provision for telling it otherwise. The attached patch provides this mechanism. This patch provided by David Bulkow, was tested on an i386 platform, which does not use the SCI override, and also on an x86_64 platform which does use an override.

2006-10-14ACPI: Processor native C-states using MWAITVenkatesh Pallipadi3-15/+151
Intel processors starting with the Core Duo support support processor native C-state using the MWAIT instruction. Refer: Intel Architecture Software Developer's Manual http://www.intel.com/design/Pentium4/manuals/253668.htm Platform firmware exports the support for Native C-state to OS using ACPI _PDC and _CST methods. Refer: Intel Processor Vendor-Specific ACPI: Interface Specification http://www.intel.com/technology/iapc/acpi/downloads/302223.htm With Processor Native C-state, we use 'MWAIT' instruction on the processor to enter different C-states (C1, C2, C3). We won't use the special IO ports to enter C-state and no SMM mode etc required to enter C-state. Overall this will mean better C-state support. One major advantage of using MWAIT for all C-states is, with this and "treat interrupt as break event" feature of MWAIT, we can now get accurate timing for the time spent in C1, C2, .. states.

The new Atmel AT91SAM9261 and AT91SAM9260 processors use a different internal watchdog peripheral. This watchdog driver is therefore AT91RM9200-specific.

2006-10-12[VOYAGER] fix genirq messJames Bottomley1-17/+25
The implementation of genirq in x86 completely broke voyager (and presumably visws). Since it's plugged into so much of the x86 infrastructure, you can't expect it to work unconverted.

However, sparc vmlinux has plenty of relocatable sections because it is being built with 'ld -r' (to allow for btfixup processing). So for sparc, modpost does do a lot of checking. Sure enough, running modpost on arch/sparc/boot/image yields no output (i.e. all is well). modpost.c check_sec_ref() has: /* We want to process only relocation sections and not .init */ if (sechdrs[i].sh_type == SHT_RELA) { // check here } else if (sechdrs[i].sh_type == SHT_REL) { // check here } Signed-off-by: Martin Habets <[email protected]> Signed-off-by: David S.

2006-10-12sh: interrupt exception handling reworkPaul Mundt4-721/+40
Kill off interrupt_table for all of the CPU subtypes, we now default in to stepping in to do_IRQ() for _all_ IRQ exceptions and counting the spurious ones, rather than simply flipping on the ones we cared about. This and enabling the IRQ by default automatically has already uncovered a couple of bugs and IRQs that weren't being caught, as well as some that are being generated far too often (SCI Tx Data Empty, for example). The general rationale is to use a marker for interrupt exceptions, test for it in the handle_exception() path, and skip out to do_IRQ() if it's found. Everything else follows the same behaviour of finding the cached EXPEVT value in r2/r2_bank, we just rip out the INTEVT read from entry.S entirely (except for in the kGDB NMI case, which is another matter). Note that while this changes the do_IRQ() semantics regarding r4 handling, they were fundamentally broken anyways (relying entirely on r2_bank for the cached code). With this, we do the INTEVT read from do_IRQ() itself (in the CONFIG_CPU_HAS_INTEVT case), or fall back on r4 for the muxed IRQ number, which should also be closer to what SH-2 and SH-2A want anyways.

2006-10-11[PATCH] epoll_pwait()Davide Libenzi1-0/+1
Implement the epoll_pwait system call, that extend the event wait mechanism with the same logic ppoll and pselect do. The definition of epoll_pwait is: int epoll_pwait(int epfd, struct epoll_event *events, int maxevents, int timeout, const sigset_t *sigmask, size_t sigsetsize); The difference between the vanilla epoll_wait and epoll_pwait is that the latter allows the caller to specify a signal mask to be set while waiting for events. Hence epoll_pwait will wait until either one monitored event, or an unmasked signal happen. If sigmask is NULL, the epoll_pwait system call will act exactly like epoll_wait.
