2012-03-22drm/nvc0-/disp: reimplement flip completion method as fifo methodBen Skeggs
Removes need for M2MF subchannel usage on NVC0+. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-03-22drm/nouveau: move fence sequence check to start of loopBen Skeggs
I want to be able to use REF_CNT from other places in the kernel without pushing a fence object onto the list of emitted fences. The current code makes an assumption that every time the acked sequence is bumped that there's at least one fence on the list that'll be signalled. This will no longer be true in the near future.

2012-03-22drm/nouveau: remove subchannel names from places where it doesn't matterBen Skeggs
These are FIFO methods, it doesn't matter what subchannel is being used. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-03-22drm/nouveau/ttm: always do buffer moves on kernel channelBen Skeggs
There was once good reasons for wanting the drm to be able to use M2MF etc on user channels, but they're not relevant anymore. For the general buffer move case, we've already lost by transferring between vram/sysmem already so the context switching overhead is minimal in comparison.

2012-03-13drm/nouveau: map first page of mmio early and determine chipset earlierBen Skeggs

2012-03-13drm/nvd0/disp: disconnect encoders before reprogramming themBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-03-13drm/nvd0/disp: move syncs/magic setup to or mode_setBen Skeggs
NVIDIA appear to do these around the same place they do the MODE_CTRL methods, and for DP at least we need to bash some extra bits in "syncs" to keep EVO happy. It's a bit of a guess as to the 6/8bpc, but i have no better idea yet. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-03-13drm/nouveau/dp: account for channel coding overhead in link trainingBen Skeggs

2012-03-13drm/nouveau/dp: make dp dpms function common, call from sor code insteadBen Skeggs
GF119 will use this too. 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/nouveau/dp: move all nv50/sor-specific code out of nouveau_dp.cBen Skeggs
Off-chip encoders (which we don't support yet anyway), and newer chipsets (such as NVD9...), will need their own code for this. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-03-13drm/nouveau/dp: make functions for executing various bios tablesBen Skeggs
More code to do the same thing, but will make it easier to handle various changes that could possibly happen the the VBIOS tables. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-03-13drm/nouveau/pm: fix oops if chipset has no pm support at allBen Skeggs
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-03-13drm/nouveau/bios: rework vbios shadowingBen Skeggs
Refactored to allow shadowing of VBIOS images longer than 64KiB, which allows us to pass the VBIOS checksum test on certain boards. There's also a workaround for reading the PROM VBIOS on some chipsets. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-03-13drm/nouveau/bios: attempt acpi rom fetch before pciromBen Skeggs
There's cards out there with completely messed up PCIROM images that have a perfectly valid signature.. Sigh! Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-03-13drm/nvd0/disp: attempt to handle more than 2 crtcs if possibleBen Skeggs
Theoretically handles CRTC2/CRTC3, should any GF119 out there actually have them enabled. The room is there for the regs etc, so why not :) Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-03-13drm/nouveau/pm: several fixes for nvc0 memory timingsRoy Spliet
This patch fixes two small issues in timing generation as spotted on several NVCx cards. In addition, the header of the file is updated to also contain (some of) the current developers of this code. Signed-off-by: Roy Spliet <r.spliet@student.tudelft.nl> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-03-13drm/nvc0/pm: restrict pll mode to clocks that can actually use itBen Skeggs
Fixes reclocking failure on some chips where we attempted to set PDAEMON to PLL mode. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-03-13drm/nouveau/dp: fix bad comparison in dp_link_train_commit()Xi Wang
The comparison (lpre == DP_TRAIN_PRE_EMPHASIS_9_5) is always false: lpre is initialized as (lane & 0x0c) >> 2, which is at most 3, while DP_TRAIN_PRE_EMPHASIS_9_5 is defined as (3 << 3). Signed-off-by: Xi Wang <xi.wang@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-03-13drm/nouveau/mxm: call mxmi to determine revision before calling mxmsBen Skeggs
There's a HP laptop out there where the MXM version in the VBIOS doesn't match what the ACPI implementation is expecting. These tables will accept 0x00 to MXMS to return latest version, but *only* if MXMI has been called first.. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-03-13drm/nouveau/pm: init only after display subsystem has been createdBen Skeggs
This patch fixes an oops cause by pm_trigger accessing the (uninitialised) crtc list. Reported-by: Roy Spliet <r.spliet@student.tudelft.nl> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2012-03-13drm/nouveau/pm: track mr2 for gddr3Ben Skeggs
There's some "extended" GDDR3 chipsets out there with EMRS2 settings that change the layout of MRS/EMRS1 bitmaps.. Sigh.. Still need to track down how exactly we're supposed to handle this. Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Martin Peres <martin.peres@labri.fr>

2012-03-13drm/nouveau/pm: introduce ram reclocking helperBen Skeggs
This will probably result in more lines of code, however, we're going to have at least 3 slightly different implementations of this very soon and I'd rather keep the ram reclocking logic separate from the hw specifics. DDR2/DDR3/GDDR3 implemented thus far, others will be added as necessary. Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Signed-off-by: Martin Peres <martin.peres@labri.fr>

2012-03-13drm/nouveau/pm: calculate memory timings at perflvl creation timeBen Skeggs
Statically generating the PFB register and MR values for each timing set turns out to be insufficient. There's at least one (so far) known piece of information which effects MR values which is stored in the perflvl entry on some chipsets (and in another table on later ones), which is disconnected from the timing table entries. After this change we will generate a timing set based on an input clock frequency instead, and have this data stored in the performance level data.

2012-03-13drm/nouveau/pm: readback boot perflvl *before* parsing vbiosBen Skeggs

2012-03-13drm/nouveau/pm: implement DDR2/DDR3/GDDR3/GDDR5 MR generation and validationRoy Spliet
Roy Spliet: - Implement according to specs - Simplify - Make array for mc latency registers Martin Peres: - squash and split all the commits from Roy - rework following Ben Skeggs comments - add a form of timings validation - store the initial timings for later use Ben Skeggs - merge slightly modified tidy-up patch with this one - remove perflvl-dropping logic for the moment Signed-off-by: Roy Spliet <r.spliet@student.tudelft.nl> Signed-off-by: Martin Peres <martin.peres@labri.fr> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2012-03-13drm/nouveau/pm: restructure bios table parsingBen Skeggs
It turns out we need access to some additional information in various VBIOS tables to handle PFB memory timings correctly. Rather than hack in parsing of the new stuff in some kludgy way, I've restructured the VBIOS parsing to be more primitive, so we can use them in more flexible ways in the future. The perflvl->timing association code is disabled for the moment until it can be reworked. We don't use this stuff yet anyway, so no harm done.

2012-03-13drm/nouveau/pm: improve memory timing generationRoy Spliet
- Rename several VBIOS entries to closer match the real world - Add the missing 0x100238 and 0x100240 register values - Parse bit 14 of the VBIOS timing table - "Magic value" -> tCWL, fixing some minor bugs in the process - Also name a few more by their name rather than their number. - Some values seem to be dependent on the memory type.
