2012-10-03drm/nouveau: restructure source tree, split core from drm implementationBen Skeggs
Future work will be headed in the way of separating the policy supplied by the nouveau drm module from the mechanisms provided by the driver core. There will be a couple of major classes (subdev, engine) of driver modules that have clearly defined tasks, and the further directory structure change is to reflect this. No code changes here whatsoever, aside from fixing up a couple of include file pathnames. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-03-13drm/nv50/hwsq: some nv92 fixesMartin Peres
The shift from hwsq_data = 0x1400 to 0x080000 actually happened in nv94, not nv92 This fixes some reclocking issues on my newly acquired nv92 Signed-off-by: Martin Peres <martin.peres@labri.fr> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-03-13drm/nv50/pm: use hwsq for engine reclocking tooBen Skeggs
Idea from Martin Peres, different implementation by me. v2: Martin Peres: - fix mast calculation Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Martin Peres <martin.peres@labri.fr>

2012-02-01drm/nv50/pm: signedness bug in nv50_pm_clocks_pre()Dan Carpenter
calc_mclk() returns zero on success and negative on failure but clk is a u32. v2: Martin Peres: - clk should be an int, not a u32 Signed-off-by: Martin Peres <martin.peres@labri.fr> Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-12-21drm/nouveau: just pass gpio line to pwm_*, not entire gpio structBen Skeggs
We don't need more than the line id to determine the PWM controller, and the GPIO interfaces are about to change somewhat. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-12-21drm/nouveau/hwsq: remove some magic, give proper opcode namesBen Skeggs

2011-12-21drm/nv50/pm: introduce hwsq-based memory reclockingMartin Peres
More work needs to be done on supporting the different memory types. v2 (Ben Skeggs): - fixed up conflicts from not having pausing patch first - restructured code somewhat to fit with how all the other code works - fixed bug where incorrect mpll_ctrl could get set sometimes - removed stuff that's cargo-culted from the binary driver - merged nv92+ display disable into hwsq - fixed incorrect opcode 0x5f magic at end of ucode Signed-off-by: Martin Peres <martin.peres@ensi-bourges.fr> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2011-12-21drm/nv50/pm: fix thinko which lead to clocks being slightly off sometimesBen Skeggs
read_pll_ref() needs to take into account the refclk src bits in 0xc040 on some chipsets, it wasn't doing this. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2011-12-21drm/nv50/pm: 0x84/0x86 can't use "1" for nvclk src, need 0x50 methodBen Skeggs

2011-12-21drm/nv50/pm: rewrite clock management, and switch to the new pm hooksBen Skeggs
This area is horrifically complicated on these chipsets, and it's likely we will need at least a few more tweaks yet. Oh yes, and it's completely disabled on IGPs for the moment. From traces, things look potentially different there yet again. Sigh... Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2011-05-16drm/nv50: improve nv50_pm_get_clock()Emil Velikov
Many of the nv50 cards have their shader and/or memory pll disabled at some stage. This patch addresses those cases, so that the function returns the correct frequency. When the shader pll is disabled, the blob reports 2*core clock Whereas for memory, the data stored in the vbios. This action is incorrect as some vbioses store a clock value that is less than the refference clock of the pll. Thus we are reporting the reff_clk as it is the frequency the pll actually operates v2 - Convert NV_INFO() messages to NV_DEBUG() Provide more information in the actuall message Signed-off-by: Emil Velikov <emil.l.velikov@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-10-05drm/nva3: split pm backend out from nv50Ben Skeggs
This will end up quite different, it makes sense for it to be completely separate. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2010-10-05drm/nouveau: pass perflvl struct to clock_pre()Ben Skeggs
On certain boards, there's BIOS scripts and memory timings that need to be modified with the memclk. Just pass in the entire perflvl struct and let the chipset-specific code decide what to do. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-09-24drm/nouveau: allow static performance level settingBen Skeggs
Guarded by a module parameter for the moment, read the code for the magic value which enables it. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2010-09-24drm/nv50: import initial clock get/set routines + hook up pm engineBen Skeggs
This will make nouveau_pm attempt to report the card's current performance level both during bootup, and through sysfs. This is a very initial implementation, and can be improved a *lot* Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
