2014-08-27radeon: Test for PCI root bus before assuming bus->selfAlex Williamson
If we assign a Radeon device to a virtual machine, we can no longer assume a fixed hardware topology, like the GPU having a parent device. This patch simply adds a few pci_is_root_bus() tests to avoid passing a NULL pointer to PCI access functions, allowing the radeon driver to work in a QEMU 440FX machine with an assigned HD8570 on the emulated PCI root bus.

2014-08-05drm/radeon: Prevent hdmi deep color if max_tmds_clock is undefined.Mario Kleiner

2014-08-05drm/radeon: Use pflip irqs for pageflip completion if possible. (v2)Mario Kleiner
Skip the "manual" pageflip completion checks via polling and guessing in the vblank handler radeon_crtc_handle_vblank() on asics which are known to reliably support hw pageflip completion irqs. Those pflip irqs are a more reliable and race-free method of handling pageflip completion detection, whereas the "classic" polling method has some small races in combination with dpm on, and with the reworked pageflip implementation since Linux 3.16. On old asics without pflip irqs, the classic method is used. On asics with known good pflip irqs, only pflip irqs are used by default, but a new module parameter "use_pflipirqs" allows to override this in case we encounter asics in the wild with unreliable or faulty pflip irqs. A module parameter of 0 allows to use the classic method only in such a case. A parameter of 1 allows to use both classic method and pflip irqs as additional band-aid to avoid some small races which could happen with the classic method alone. The setting 1 gives Linux 3.16 behaviour. Hw pflip irqs are available since R600. Tested on DCE-4, AMD Cedar - FirePro 2270. v2: agd5f: only enable pflip interrupts on DCE4+ as they are not reliable on older asics.
