* drm/radeon: use system_wq instead of dev_priv->wqTejun Heo2011-01-061-1/+0
| | | | | | | | | | | | | | | | | | With cmwq, there's no reason for radeon to use a dedicated workqueue. Drop dev_priv->wq and use system_wq instead. Because radeon_driver_irq_uninstall_kms() may be called from unsleepable context, the work items can't be flushed from there. Instead, init and flush from radeon_irq_kms_init/fini(). While at it, simplify canceling/flushing of rdev->pm.dynpm_idle_work. Always initialize and sync cancel instead of being unnecessarily smart about it.

* drm/radeon/kms: manage r300 CMASK RAM access and allow CMASK clearMarek Olšák2011-01-061-1/+2
| | | | | | | | | | | | The CMASK RAM is for colorbuffer compression (used in conjunction with MSAA). Only one user (filp) can access it. The CMASK RAM access is managed in the same way as Hyper-Z, but there is a separate ioctl, because an app that uses MSAA does not necessarily have to use zbuffering.

The GART aperture size has to be in the form of 2^X bytes, where X is from 25 to 31 2. The GART aperture MC base has to be aligned to a boundary equal to the size of the aperture. 3. The GART page table has to be aligned to the boundary equal to the size of the table. 4. The GART page table size is: table_entry_size * (aperture_size / page_size) 5.

* DRM / radeon / KMS: Fix hibernation regression related to radeon PM (was: ↵Rafael J. Wysocki2010-07-011-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Re: [Regression, post-2.6.34] Hibernation broken on machines with radeon/KMS and r300) There is a regression from 2.6.34 related to the recent radeon power management changes, caused by attempting to cancel a delayed work item that's never been scheduled. 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).

You can select the pm method by echoing the selected method ("dynpm" or "profile") to power_method in sysfs. - Expose basic 4 profile in profile method "default" - default clocks "auto" - select between low and high based on ac/dc state "low" - DC, low power mode "high" - AC, performance mode The current base profile is "default", but it should switched to "auto" once we've tested on more systems. Switching the state is a matter of echoing the requested profile to power_profile in sysfs. The lowest power states are selected automatically when dpms turns the monitors off in all states but default. - Remove dynamic fence-based reclocking for the moment. We can revisit this later once we have basic pm in. - Move pm init/fini to modesetting path. pm is tightly coupled with display state. Make sure display side is initialized before pm. - Add pm suspend/resume functions to make sure pm state is properly reinitialized on resume. - Remove dynpm module option.

The driver scales the sclk dynamically based on the number of queued fences. dynpm only scales sclk dynamically in single head mode. Echoing x.y to power_state selects a static power state (x) and clock mode (y). This allows you to statically select a power state and clock mode. Selecting a static clock mode will disable dynpm.

You need to wait for the GUI engine (2D, 3D, CP, etc.) to be idle before changing clocks or adjusting engine parameters. (v2) Fix gui idle enable on pre-r6xx asics (v3) The gui idle interrrupt status bit is permanently asserted on pre-r6xx chips, but the interrrupt is still generated. workaround it in the driver.
