| | | | | | | | | | | | | This provides a sledgehammer approach for clearing the TLBs, only to be used in cases where we know we will never want to use the mappings again and have no interest in preserving state. This also destroys wired entries. The primary use for this is when we are either entering or exiting the kernel completely, in the latter case as a precursor for CPU reset by MMU.

First, it did not, in fact, disable the CRT plug interrupt -- it disabled all the other hotplug interrupts. It seems rather doubtful that that bit of the patch fixed anything, so let's just remove it. (If you want to add it back, you probably meant ~CRT_HOTPLUG_INT_EN.) Second, on at least my GM45, setting CRT_HOTPLUG_ACTIVATION_PERIOD_64 and CRT_HOTPLUG_VOLTAGE_COMPARE_50 (when they were previously unset) causes a hotplug interrupt about three seconds later. The old code never restored PORT_HOTPLUG_EN so this could only happen once, but they new code restores those registers. So just set those bits when we set up the interrupt in the first place.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Gen3 chips have slightly different flip commands, and also contain a bit that indicates whether a "flip pending" interrupt means the flip has been queued or has been completed. So implement support for the gen3 flip command, and make sure we use the flip pending interrupt correctly depending on the value of ECOSKPD bit 0.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hardware will set the flip pending ISR bit as soon as it receives the flip instruction, and (supposedly) clear it once the flip completes (e.g. at the next vblank). If we try to send down a flip instruction while the ISR bit is set, the hardware can become very confused, and we may never receive the corresponding flip pending interrupt, effectively hanging the chip.

The old way (sources, enable, unmask) gives a window during which interrupt conditions would appear in ISR but would never reach IIR and thus never raise an IRQ. Since interrupts only trigger on rising edges in ISR, this would lead to conditions where (for example) output hotplugging would never fire an interrupt because it was already stuck on in ISR. Also, since we know IIR and PIPExSTAT have been cleared during irq_preinstall, don't clear them again during irq_postinstall, nothing good can come of that.

Previously this was a fortuitous byproduct of userspace using pwrite() to upload the image data into the cursor. The redundant clflush was removed in commit 9b8c4a and so the image was no longer being flushed out of the caches into main memory. One could also devise a scenario where the cursor was rendered by the GPU, prior to being attached as the cursor, resulting in similar corruption due to the missing MI_FLUSH.

However, the code as is has some other issues potentially leading to visible problems. First, the mutex around cancel_delayed_work() in radeon_pm_suspend() doesn't really serve any purpose, because cancel_delayed_work() only tries to delete the work's timer. Moreover, it doesn't prevent the work handler from running, so the handler can do some wrong things if it wins the race and in that case it will rearm itself to do some more wrong things going forward. So, I think it's better to wait for the handler to return in case it's already been queued up for execution. Also, it should be prevented from rearming itself in that case. Second, in radeon_set_pm_method() the cancel_delayed_work() is not sufficient to prevent the work handler from running and queing up itself for the next run (the failure scenario is that cancel_delayed_work() returns 0, so the handler is run, it waits on the mutex and then rearms itself after the mutex has been released), so again the work handler should be prevented from rearming itself in that case.. Finally, there's a potential deadlock in radeon_pm_fini(), because cancel_delayed_work_sync() is called under rdev->pm.mutex, but the work handler tries to acquire the same mutex (if it wins the race). Fix the issues described above. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Reviewed-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
