2011-09-20drm/nouveau: remove allocations from gart populate() hookBen Skeggs1-45/+21
Since some somewhat questionable changes a while back, TTM provides a completely empty array of struct dma_address that stays around for the entire lifetime of the TTM object. Lets use this array, *always*, rather than wasting yet more memory on another array who's purpose is identical, as well as yet another bool array of the same size saying *which* of the previous two arrays to use... This change will also solve the high order allocation failures seen by some people while using nouveau. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-09-20drm/nvc0/fb: slightly improve PMFB intr handling, move out of nvc0_graph.cBen Skeggs2-18/+27
I'm still not certain how to determine the number of SUBPs are present on a given board. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2011-09-20drm/nouveau: if requested, try harder at disabling sysmem pushbufsBen Skeggs1-6/+10
On >=nv50, userspace would still end up allocating pushbufs in GART. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-09-20drm/nv50/gr: enable ctxprog xfer only when we need it to save powerMartin Peres1-0/+5
This patch adds instructions to ctxprog and by doing, impacts context switching performance. My testcase showed a 1% performance cost using glxgears that is a context-switch bound application. Please test and report bugs/performance/power/other. Many thanks to Maxim Levitsky for his dedicated work on lowering power consumption with nouveau.

2011-09-20drm/nouveau/dp: add support for displayport table 0x30Ben Skeggs1-22/+48
Written from observations of my NVD9's vbios, completely untested due to my NVD9 lacking actual DisplayPort connectors.. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-09-20drm/nouveau/dp: return master dp table pointer too when looking up encoderBen Skeggs4-70/+66
Will need to be able to distinguish 2.0/2.1 from 3.0 soon. Also, move the vbios parsing to nouveau_dp where it belongs. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-09-20drm/nouveau/bios: simplify U/d table hash matching func to just matchBen Skeggs2-51/+40

2011-09-20drm/nvc0/gr: remove MODULE_FIRMWARE() linesBen Skeggs1-17/+0
We don't use these by default anymore, and there's been complaints from a number of places thinking that the firmware blobs are required still. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-09-20drm/nouveau/dp: use alternate lane mask for nvafBen Skeggs1-1/+10

2011-09-20drm/nv40/pm: write nv40-specific reclocking routinesBen Skeggs4-4/+342
Not 100% perfect yet, but a good start towards what it'll look like in the end. Actually seems stable on a NV44 I have here, as much as running around OA for a fair amount of time constantly switching between performance levels can prove.. My NV49 isn't quite so happy, and semaphores mess up somehow (sometimes) as a result of the memory reclocking. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-09-20drm/nv40/pm: parse geometric delta clock from vbiosBen Skeggs1-2/+3
This changes the meaning of what we reported as "core" clock previously. The shader/rop units are allegedly supposed to be run at the base clock listed in the perf table, while the geometric clock can be bumped from this value on some boards. So that we can report both, we'll report the base clock as "shader" (since the shaders *do* run at it), and the geometric clock as "core". Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2011-09-20drm/nouveau: workaround semaphore hw bug causing unnecessary interruptsBen Skeggs1-1/+1
The HW will only accept the DMA_FROM_MEMORY class for DMA_SEMAPHORE without asking the driver to intervene. It appears that semaphores will work correctly even without DMA_IN_MEMORY, so lets avoid the large amount of interrupts generated by x-chan sync. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-09-20drm/nouveau/tmr: fix miscalculation of ratio on pre-nv4x chipsetsBen Skeggs1-26/+2

2011-09-20drm/nouveau: enable hwmon support when both nouveau/hwmon are built as modules.Ken Milmore1-3/+3
The nouveau hwmon temperature support currently only functions when hwmon is compiled into the kernel. There's no reason why this shouldn't also work when both hwmon and nouveau are modularised (as is the case with Slackware's stock kernels).
