* / x86 ACPI: Blacklist two HP machines with buggy BIOSesRafael J. Wysocki2008-10-06
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a bug in the BIOSes of some HP boxes with AMD Turions which connects IO-APIC pins with ACPI thermal trip points in such a way that if the state of the IO-APIC is not as expected by the (buggy) BIOS, the thermal trip points are set to insanely low values (usually all of them become 16 degrees Celsius). As a result, thermal throttling kicks in and knock the system down to its shoes. Unfortunately some of the recent IO-APIC changes made the bug show up. To prevent this from happening, blacklist machines that are known to be affected (nx6115 and 6715b in this particular case). This fixes http://bugzilla.kernel.org/show_bug.cgi?id=11516 listed as a regression from 2.6.26. On my box it was caused by: commit 691874fa96d6349a8b60f8ea9c2bae52ece79941 Author: Maciej W.

* / [S390] nohz: Fix __udelay.Heiko Carstens2008-10-03
|/ | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a regression that came with 934b2857cc576ae53c92a66e63fce7ddcfa74691 ("[S390] nohz/sclp: disable timer on synchronous waits."). If udelay() gets called from a disabled context it sets the clock comparator to a value where it expects the next interrupt. When the interrupt happens the clock comparator gets not reset and therefore the interrupt condition doesn't get cleared. The result is an endless timer interrupt loop. In addition this patch fixes also the following: rcutorture reveals that our __udelay implementation is still buggy, since it might schedule tasklets, but prevents their execution: NOHZ: local_softirq_pending 42 NOHZ: local_softirq_pending 02 NOHZ: local_softirq_pending 142 NOHZ: local_softirq_pending 02 To fix this we make sure that only the clock comparator interrupt is enabled when the enabled wait psw is loaded. Also no code gets called anymore which might schedule tasklets. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

| | | | | | | | | | | | Commit 00c5372d37a78990c1530184a9c792ee60a30067 caused the MPC8544DS board to hang at boot. The MPC8544DS is unique in that it doesn't use the PCI slots on the ULI (unlike the MPC8572DS or MPC8610HPCD). So the dummy read at the end of the address space causes us to hang.

* | MN10300: Fix IRQ handlingDavid Howells2008-10-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the IRQ handling on the MN10300 arch. This patch makes a number of significant changes: (1) It separates the irq_chip definition for edge-triggered interrupts from the one for level-triggered interrupts. This is necessary because the MN10300 PIC latches the IRQ channel's interrupt request bit (GxICR_REQUEST), even after the device has ceased to assert its interrupt line and the interrupt channel has been disabled in the PIC. So for level-triggered interrupts we need to clear this bit when we re-enable - which is achieved by setting GxICR_DETECT but not GxICR_REQUEST when writing to the register. Not doing this results in spurious interrupts occurring because calling mask_ack() at the start of handle_level_irq() is insufficient - it fails to clear the REQUEST latch because the device that caused the interrupt is still asserting its interrupt line at this point. (2) IRQ disablement [irq_chip::disable_irq()] shouldn't clear the interrupt request flag for edge-triggered interrupts lest it lose an interrupt. (3) IRQ unmasking [irq_chip::unmask_irq()] also shouldn't clear the interrupt request flag for edge-triggered interrupts lest it lose an interrupt. (4) The end() operation is now left to the default (no-operation) as __do_IRQ() is compiled out. This may affect misrouted_irq(), but according to Thomas Gleixner it's the correct thing to do. (5) handle_level_irq() is used for edge-triggered interrupts rather than handle_edge_irq() as the MN10300 PIC latches interrupt events even on masked IRQ channels, thus rendering IRQ_PENDING unnecessary. It is sufficient to call mask_ack() at the start and unmask() at the end. (6) For level-triggered interrupts, ack() is now NULL as it's not used, and there is no effective ACK function on the PIC. mask_ack() is now the same as mask() as the latch continues to latch, even when the channel is masked. Further, the patch discards the disable() op implementation as its now the same as the mask() op implementation, which is used instead. It also discards the enable() op implementations as they're now the same as the unmask() op implementations, which are used instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I tracked down the shutdown regression to CPUs not dying when being shut down during power-off. This turns out to be due to the system_state being SYSTEM_POWER_OFF, which this code doesn't take as a valid state for shutting off CPUs in. This has never made sense to me, but when I added hotplug code to implement hibernate I only "made it work" and did not question the need to check the system_state. Thomas Gleixner helped me dig, but the only thing we found is that it was added with the original commit that added CPU hotplug support.

The current device tree node for the PCI bridge sits under the tsi-bridge node. That's not obviously wrong, but the PCI bridge translates some PCI spaces into CPU address ranges which were not translated by the "ranges" property in tsi-bridge node. We used to get away with this problem because the PCI bridge discovery code was also buggy, assuming incorrectly that PCI host bridge nodes were always directly under the root bus and treating the translated addresses as raw CPU addresses, rather than parent bus addresses. This has since been fixed, thus breaking Holly. This could be fixed by adding extra translations to the tsi-bridge node, but this patch instead moves the Holly PCI bridge out of the tsi-bridge node to the root bus. This makes the tsi-bridge node represent only the built-in IO devices in the bridge, with a more-or-less contiguous address range. This is the same convention used on Freescale SoC chips, where the "soc" node represents only the IMMR region, and the PCI and other bus bridges are separate nodes under the root bus.
