Patch 1 and 2 implement wait-for-vblank, required to remove flicker when reclocking memory Patch 3 and 4 allow me to do things between waiting for VBLANK and disabling FB, like pause PFIFO and wait for the engines to idle. This minimises the time PFIFO is paused, thus maximises performance. The rest of the patches speak for themselves. As the actual memory reclocking script is still somewhat prone

Patch 1 fixes nva3 bailing due to not finding the right ramcfg Patch 2 is a resend rebased on 3.17.0-rc4 for setting the vblank period Patch 3-5 handle writes to per-partition registers, for which NVA3 does not have special broadcast regs available. Patch 6 removes local structs from NVA3 reclocking in favour of the already existing "ram->base." variables, like in NVE0 As always,

This patch series sets dev->vblank_disable_immediate = true on radeon/amdgpu-kms, nouveau-kms for nv50+, and vc4 for the real kms driver (as opposed to dispmanx firmware backed kms). All the drivers should be ready in theory, given their implementation, for fast vblank disable/enable. In practice, i have performed timing tests with my measurement equipment for all those drivers with the

It seems it was only locking up in the context of nouveau_hw_save_vga_fonts, when it actually did something (because the console wasn't already in graphics mode).

This patch series adds TV-out modesetting support to the KMS implementation. I've tried to test it on all the hardware I've got at hand (that is nv11, nv17, nv34, nv35, nv40, nv4b) with every possible output combination; I believe it has reached a mergeable state, however it depends on some commits from drm-next that haven't got into Linus' tree yet, if you agree to merge this
