From 36e9e1eab777e077f7484d309ff676d0568e27d1 Mon Sep 17 00:00:00 2001 From: Suresh Siddha Date: Mon, 15 Mar 2010 14:33:06 -0800 Subject: x86: Handle legacy PIC interrupts on all the cpu's Ingo Molnar reported that with the recent changes of not statically blocking IRQ0_VECTOR..IRQ15_VECTOR's on all the cpu's, broke an AMD platform (with Nvidia chipset) boot when "noapic" boot option is used. On this platform, legacy PIC interrupts are getting delivered to all the cpu's instead of just the boot cpu. Thus not initializing the vector to irq mapping for the legacy irq's resulted in not handling certain interrupts causing boot hang. Fix this by initializing the vector to irq mapping on all the logical cpu's, if the legacy IRQ is handled by the legacy PIC.

This covers too many CPUs. Meanwhile a respective erratum for the underlying problem was filed (#400). This patch adds the logic to check whether erratum #400 applies to a given CPU. Especially for CPUs where SMI/HW triggered C1e is not supported, c1e_idle() doesn't need to be used. We can check this by looking at the respective OSVW bit for erratum #400.

To correctly access these registers LOCOMO_SPI must always be included in the address calculation. There are two places in locomo.c where this is not done. The first one, in locomo_suspend, actually results in a write to LOCOMO_ST instead of LOCOMO_SPICT. The second is in __locomo_probe and results in a write to LOCOMO_MCSX2 instead of LOCOMO_SPIIE. Fix these by including LOCOMO_SPI in the calculation.

This entire function is guarded with a spin_lock_irqsave at the start of the function and a spin_unlock_irqrestore at the end. As each byte is transferred, the i2c ACK from the DAC is checked. Currently, if the ACK is missing the function simply returns without the unlock. It also leaves the i2c bus in an invalid state since the last byte transferred did not have a "stop" condition and leave the bus idle. Fix this by adding an exit path using goto.

The current implementation uses dmb() for mb() and friends but this is not sufficient. The DMB only ensures the relative ordering of the observability of accesses by other processors or devices acting as masters. In case of DMA transfers started by writes to device memory, the relative ordering is not ensured because accesses to slave ports of a device are not considered observable by the DMB definition. A DSB is required for the data to reach the main memory (even if mapped as Normal Non-cacheable) before the device receives the notification to begin the transfer. Furthermore, some L2 cache controllers (like L2x0 or PL310) buffer stores to Normal Non-cacheable memory and this would need to be drained with the outer_sync() function call. The patch also allows platforms to define their own mandatory barriers implementation by selecting CONFIG_ARCH_HAS_BARRIERS and providing a mach/barriers.h file. Note that the SMP barriers are unchanged (being DMBs as before) since they are only guaranteed to work with Normal Cacheable memory.

Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

The event hence gets filtered in perf_swevent_add(). Scheduler's context switches events use task_pt_regs() to get the context when the event occured which is a wrong thing to do as this won't give us the place in the kernel where we went to sleep but the place where we left userspace. The result is even more wrong if we switch from a kernel thread. Use the hot regs snapshot for both events as they belong to the non-interrupt/exception based events family. Unlike page faults or so that provide the regs matching the exact origin of the event, we need to save the current context. This makes the task migration event working and fix the context switch callchains and origin ip.

This is a chipset erratum. Thomas: You mentioned we can retain this check only for known-buggy and hpet debug kind of options. But here is the simple workaround patch for this particular erratum. Some chipsets have a erratum due to which read immediately following a write of HPET comparator returns old comparator value instead of most recently written value. Erratum 15 in "Intel I/O Controller Hub 9 (ICH9) Family Specification Update" (http://www.intel.com/assets/pdf/specupdate/316973.pdf) Workaround for the errata is to read the comparator twice if the first one fails.

In the normal case, when the RTC frequency is set, the rtc driver tells the hpet code about it here: int hpet_set_periodic_freq(unsigned long freq) { uint64_t clc; if (!is_hpet_enabled()) return 0; if (freq <= DEFAULT_RTC_INT_FREQ) hpet_pie_limit = DEFAULT_RTC_INT_FREQ / freq; else { clc = (uint64_t) hpet_clockevent.mult * NSEC_PER_SEC; do_div(clc, freq); clc >>= hpet_clockevent.shift; hpet_pie_delta = (unsigned long) clc; } return 1; } If freq is set to 64Hz (DEFAULT_RTC_INT_FREQ) or lower, then hpet_pie_limit (a static) is set to non-zero. Then, on every one-shot HPET interrupt, hpet_rtc_timer_reinit is called to compute the next timeout. Well, that function has this logic: if (!(hpet_rtc_flags & RTC_PIE) || hpet_pie_limit) delta = hpet_default_delta; else delta = hpet_pie_delta; Since hpet_pie_limit is not 0, hpet_default_delta is used. That corresponds to 64Hz. Now, if you set a different rtc frequency, you'll take the else path through hpet_set_periodic_freq, but unfortunately no one resets hpet_pie_limit back to 0. Boom....now you are stuck with 64Hz RTC interrupts forever. The patch below just resets the hpet_pie_limit value when requested freq is greater than DEFAULT_RTC_INT_FREQ, which we think fixes this problem.

Fix this by using a struct stack_frame with 32-bit pointers when the TIF_IA32 flag is set. Note that TIF_IA32 flag must be used, and not is_compat_task(), because the latter is only set when the 32-bit process is executing a syscall, which may not always be the case (when tracing page fault events for example).

Thus leading to kernel panic. Don't call enable_IR_x2apic() and default_setup_apic_routing() from APIC_init_uniprocessor() in CONFIG_SMP case.

A failure case is where DMA is being used for SPI transmit and receive channels on OMAP L138. In this case there is a single bit that controls all event generation from the SPI peripheral. Therefore it is possible that between when edma_stop() has been called for the transmit channel on a previous transfer and edma_start() is called for the transmit channel on a subsequent transfer, that a transmit event has been generated. The fix is to clear events in edma_start(). This prevents false events from being processed when events are enabled for that channel.

This causes tests of the following sort: /* don't pin down non-user-based iovecs */ if (segment_eq(get_fs(), KERNEL_DS)) return NULL; to malfunction. To fix this, make USER_DS the top of RAM instead of the top of the non-IO address space, and make KERNEL_DS one more than the top of the non-IO address space. Also get rid of FRV's __addr_ok() as nothing uses it.
