Commit 1dce6264045cd23e9c07574ed0bb31c7dce9354f introduced a regression spotted on several G94 (FDObz #85160). This device seems to expect the vblank period to be set after setting scale instead of before. V2: shove this in a separate function This is a candidate bug-fix for 3.18 Signed-off-by: Roy Spliet <rspliet at eclipso.eu> Tested-by: Zlatko Calusic <zcalusic at bitsync.net>

MAD IMM has a very specific SDST == SSRC2 requirement, so don't emit Signed-off-by: Roy Spliet <rspliet at eclipso.eu> --- .../drivers/nouveau/codegen/nv50_ir_emit_nv50.cpp | 18 ++++++++++++------ .../drivers/nouveau/codegen/nv50_ir_target_nv50.cpp | 2 +- 2 files changed, 13 insertions(+), 7 deletions(-) diff --git a/src/gallium/drivers/nouveau/codegen/nv50_ir_emit_nv50.cpp

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

This should probably be folded into the previous patch to avoid breaking bisectability on nve0 On Thu, Sep 4, 2014 at 10:58 AM, Roy Spliet <rspliet at eclipso.eu> wrote: > This used to be done implicitly > > Signed-off-by: Roy Spliet <rspliet at eclipso.eu> > --- > drivers/gpu/drm/nouveau/core/subdev/fb/ramnve0.c | 5 +++++ > 1 file changed, 5 insertions(+) >

This patch fixes the pwr firmware to play nicely at least on NVA3. Because Martin might send more patches soon, I didn't include a regenerated nvXX.fuc.h. To me it makes more sense if all patches are merged then, and a final patch regenerates the headers in one go. Of course, I did test this patch and found it to work as intended, so feel free to pick up as you please.

Add emission rules for negative and saturate flags for MAD 4-byte opcodes, and get rid of constraints. Short MAD has a very specific SDST == SSRC2 requirement, and since MAD IMM is short notation + 4-byte immediate, don't have the compiler create MAD IMM instructions yet. V2: Document MAD as supported short form Signed-off-by: Roy Spliet <rspliet at eclipso.eu> ---

Following a series of patches to improve nouveaus clock tree parsing. Reclocking these engines (all but memory) is pretty stable on the cards I've tested. Please review and merge when approved. These patches do not solve the problem that core/shader engine doesn't like to be clocked up too far without fb following, with visible corruption as a result. I suspect this problem is unrelated

V2: clarify code, commit msgs, add comments. Drop code to was supposed to make register assignment prefer SDST == SRC2 (patch 2) for now, because it didn't quite do what I intended.

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,

The value set is an underestimate, but with non-reduced vblanking this should give us plenty of time Hey Roy, I've merged all (squashed the kepler change into the commit where it's needed too) except this patch, which needs to be rebased on top of 3.17-rc.

In bulletpoints: - Add some support for G94 and G96 reclocking. Has been tested on literally two cards, which is hardly adequate as "full coverage". On the other hand, the changes were small enough to make me confident this might work for others as well. - Fix NV50 wait for VBLANK when no monitor is plugged in. - Voltage related inprovements for GT21x. - Slightly improve Keplers

Adds reclocking for NVA0, and a whole lot of work for other cards. Had these patches collecting dust for a little, but tested them with both my NVA0, and Martin's a while back. Success not guaranteed, but should be quite a leap forward. Happy reviewing and testing. Cheers, Roy

Resend of patch #7 to fix behaviour when failing to pause parts of the GPU

Sometimes boot scripts leave the "DLL reset" bit on, but it shouldn't be set on every MR write. V2 addresses this by forcing DLL reset off in MR generation
