2012-06-21drm/radeon: apply Murphy's law to the kms irq code v3Christian Koenig
1. It is really dangerous to have more than one spinlock protecting the same information. 2. radeon_irq_set sometimes wasn't called with lock protection, so it can happen that more than one CPU would tamper with the irq regs at the same time. 3. The pm.gui_idle variable was assuming that the 3D engine wasn't becoming idle between testing the register and setting the variable. So just remove it and test the register directly. v2: Also handle the hpd irq code the same way. v3: Rename hpd parameter for clarification.

2011-03-14drm/radeon: fix problem with changing active VRAM size. (v2)Dave Airlie
So we used to use lpfn directly to restrict VRAM when we couldn't access the unmappable area, however this was removed in 93225b0d7bc030f4a93165347a65893685822d70 as it also restricted the gtt placements. However it was only later noticed that this broke on some hw. This removes the active_vram_size, and just explicitly sets it when it changes, TTM/drm_mm will always use the real_vram_size, and the active vram size will change the TTM size used for lpfn setting. We should re-work the fpfn/lpfn to per-placement at some point I suspect, but that is too late for this kernel.

2011-01-17drm/radeon/kms: balance asic_reset functionsAlex Deucher
First, we were calling mc_stop() at the top of the function which turns off all MC (memory controller) clients, then checking if the GPU is idle. If it was idle we returned without re-enabling the MC clients which would lead to a blank screen, etc. This patch checks if the GPU is idle before calling mc_stop(). Second, if the reset failed, we were returning without re-enabling the MC clients. This patch re-enables the MC clients before returning regardless of whether the reset was successful or not.

2011-01-06drm/radeon: use system_wq instead of dev_priv->wqTejun Heo
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.

2010-11-22drm/kms/radeon: Reorder vblank and pageflip interrupt handling.Mario Kleiner
In the vblank irq handler, calls to actual vblank handling, or at least drm_handle_vblank(), need to happen before calls to radeon_crtc_handle_flip(). Reason: The high precision pageflip timestamping and some other pageflip optimizations will need the updated vblank count and timestamps for the current vblank interval. These are calculated in drm_handle_vblank(), therefore it must go first.

The driver can then read the values from the shadow rather than reading back from the register across the bus. Writeback can be disabled by setting the no_wb module param to 1.

2010-08-02drm/radeon/kms: check/restore sanity before doing anything else with GPU.Dave Airlie
On systems using kexec, the new kernel is booted straight from the old kernel, without any warning to the graphics driver. So the GPU is basically left as-is in a running state, however the CPU side is completly reset. Without stating the saneness of anyone using kexec on live systems, we should at least try not to crash the GPU.

- Separate dynpm and profile based power management methods.

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.
