2011-06-08drm/radeon/kms: disable hdmi audio by defaultAlex Deucher1-2/+2
The current RE'd code causes blank screens and display problems on a lot of systems. So disable it by default for now. It can still be enabled by setting the audio parameter to 1. E.g.: radeon.audio=1 Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=38010 https://bugs.freedesktop.org/show_bug.cgi?id=27731 https://bugs.freedesktop.org/show_bug.cgi?id=35970 https://bugs.freedesktop.org/show_bug.cgi?id=26195 and many other reported problems.

2011-06-08drm/radeon/kms: fix for radeon on systems >4GB without hardware iommuDaniel Haid1-0/+1
On my x86_64 system with >4GB of ram and swiotlb instead of a hardware iommu (because I have a VIA chipset), the call to pci_set_dma_mask (see below) with 40bits returns an error. But it seems that the radeon driver is designed to have need_dma32 = true exactly if pci_set_dma_mask is called with 32 bits and false if it is called with 40 bits. I have read somewhere that the default are 32 bits. So if the call fails I suppose that need_dma32 should be set to true. And indeed the patch fixes the problem I have had before and which I had described here: http://choon.net/forum/read.php?21,106131,115940 Acked-by: Alex Deucher <[email protected]> cc: [email protected] Signed-off-by: Dave Airlie <[email protected]>

2011-06-08x86: cpu-hotplug: Prevent softirq wakeup on wrong CPUThomas Gleixner1-0/+13
After a newly plugged CPU sets the cpu_online bit it enables interrupts and goes idle. The cpu which brought up the new cpu waits for the cpu_online bit and when it observes it, it sets the cpu_active bit for this cpu. The cpu_active bit is the relevant one for the scheduler to consider the cpu as a viable target. With forced threaded interrupt handlers which imply forced threaded softirqs we observed the following race: cpu 0 cpu 1 bringup(cpu1); set_cpu_online(smp_processor_id(), true); local_irq_enable(); while (!cpu_online(cpu1)); timer_interrupt() -> wake_up(softirq_thread_cpu1); -> enqueue_on(softirq_thread_cpu1, cpu0); ^^^^ cpu_notify(CPU_ONLINE, cpu1); -> sched_cpu_active(cpu1) -> set_cpu_active((cpu1, true); When an interrupt happens before the cpu_active bit is set by the cpu which brought up the newly onlined cpu, then the scheduler refuses to enqueue the woken thread which is bound to that newly onlined cpu on that newly onlined cpu due to the not yet set cpu_active bit and selects a fallback runqueue. Not really an expected and desirable behaviour. So far this has only been observed with forced hard/softirq threading, but in theory this could happen without forced threaded hard/softirqs as well. It's probably unobservable as it would take a massive interrupt storm on the newly onlined cpu which causes the softirq loop to wake up the softirq thread and an even longer delay of the cpu which waits for the cpu_online bit.

2011-06-08MD: add sync_super to mddev_t structJonathan Brassow2-2/+14
Add the 'sync_super' function pointer to MD array structure (struct mddev_s) If device-mapper (dm-raid.c) is to define its own on-disk superblock and be able to load it, there must still be a way for MD to initiate superblock updates. The simplest way to make this happen is to provide a pointer in the MD array structure that can be set by device-mapper (or other module) with a function to do this. If the function has been set, it will be used; otherwise, the method with be looked up via 'super_types' as usual.

Move personality and sync/recovery thread starting outside md_run. Moving the wakeup's of the personality and sync/recovery threads out of md_run and into do_md_run and mddev_resume solves two issues: 1) It allows bitmap_load to be called before the sync_thread is run and 2) when MD personalities are used by device-mapper (dm-raid.c), the start-up of the array is better alligned with device-mapper primatives (CTR/resume/suspend/DTR). I/O - in this case, recovery operations - should not happen until after a resume has taken place. Signed-off-by: Jonathan Brassow <[email protected]> Signed-off-by: NeilBrown <[email protected]>

2011-06-07MN10300: die_if_no_fixup() shouldn't use get_user() as it doesn't call set_fs()David Howells1-2/+2
die_if_no_fixup() shouldn't use get_user() as it doesn't call set_fs() to indicate that it wants to probe a kernel address. Instead it should use probe_kernel_read(). This fixes the problem of gdb seeing SIGILL rather than SIGTRAP when hitting the KGDB special breakpoint upon SysRq+g being seen. The problem was that die_if_no_fixup() was failing to read the opcode of the instruction that caused the exception, and thus not fixing up the exception. This caused gdb to get a S04 response to the $? request in its remote protocol rather than S05 - which would then cause it to continue with $C04 rather than $c in an attempt to pass the signal onto the inferior process. The kernel, however, does not support $Cnn, and so objects by returning an E22 response, indicating an error. gdb does not expect this and prints: warning: Remote failure reply: E22 and then returns to the gdb command prompt unable to continue.

2011-06-07Do not skip interrupt sources in sun4d interrupt handler and acknowledge ↵oftedal1-9/+5
interrupts correctly During the introduction of genirq on sparc32 bugs were introduced in the interrupt handler for sun4d. The interrupts handler checks the status of the various sbus interfaces in the system and generates a virtual interrupt, based upon the location of the interrupt source. This lookup was broken by restructuring the code in such a way that index and shift operations were performed prior to comparing this against the values read from the interrupt controllers. This could cause the handler to loop eternally as the interrupt source could be skipped before any check was performed. Additionally sun4d_encode_irq performs shifting internally, so it should not be performed twice. In sun4d_unmask interrupts were not correctly acknowledged, as the corresponding bit it the interrupt mask was not actually cleared.

sun4d_build_device_irq was called without a valid platform_device when the system timer was initialized on sun4d systems. This caused a NULL pointer crash. Josip Rodin suggested that the current sun4d_build_device_irq should be split into two functions. So that the timer initialization could skip the slot and sbus interface detection code in sun4d_build_device_irq, as this does not make sence due to the timer interrupts not being generated from a device located on sbus.

2011-06-07libata: fix unexpectedly frozen port after ata_eh_reset()Tejun Heo1-4/+8
To work around controllers which can't properly plug events while reset, ata_eh_reset() clears error states and ATA_PFLAG_EH_PENDING after reset but before RESET is marked done. As reset is the final recovery action and full verification of devices including onlineness and classfication match is done afterwards, this shouldn't lead to lost devices or missed hotplug events. Unfortunately, it forgot to thaw the port when clearing EH_PENDING, so if the condition happens after resetting an empty port, the port could be left frozen and EH will end without thawing it, making the port unresponsive to further hotplug events. Thaw if the port is frozen after clearing EH_PENDING.

2011-06-07staging: ath6kl: Fix a kernel panic during suspend/resumeVasanthakumar Thiagarajan1-1/+2
The kernel panic happens when we try to complete a pending scan request while going to suspend state. The cause for this kernel panic is accessing a freed memory (ar->arWmin). This is freed before ar6k_cfg80211_scanComplete_event() getting called where it is dereferenced.

2011-06-07staging: gma500: get control from firmware framebuffer if conflictsMichael Chang1-0/+10
Many Linux distributions would enable vesafb in order to display early stage boot splash. In this case, we will get garbled X Window screen if running X fbdev on psbfb. This is because fb0 is occupied by vesafb while psbfb is on fb1. They tried to drive the same pieces of hardware at the same time. With unmodified X start-up, it would try to use default fb0 framebuffer device and unfortunately it is now broken becaues fb1 supersedes it. We should let psbfb takeover framebuffer control from vesafb to get around this problem.

2011-06-07staging: gma500: Skip bogus LVDS VBT mode and check for LVDS before adding ↵Patrik Jakobsson2-5/+23
backlight On the Fit-PC2 the VBT reports an invalid fixed panel mode for LVDS, this gets in the way for SDVO. This patch makes VBT parsing skip the invalid mode. When there is no LVDS output the backlight support crashes so the patch also checks for this before enabling it.
