2021-01-29drm/nouveau/kms/nv50-: Fix locking for audio callbacksLyude Paul3-31/+43
Noticed that I wasn't paying close enough attention the last time I looked at our audio callbacks, as I completely missed the fact that we were figuring out which audio-enabled connector goes to each encoder by checking it's state, but without grabbing any of the appropriate modesetting locks to do so. That being said however: trying to grab modesetting locks in our audio callbacks would be very painful due to the potential for locking inversion between HDA and DRM. So, let's instead just copy what i915 does again - add our own audio lock to protect audio related state, and store each audio enabled connector in each nouveau_encoder struct so that we don't need to check any atomic states.

2021-01-29drm/nouveau/kms/nv50-: Lookup current encoder/crtc from atomic stateLyude Paul1-21/+38
Despite being an atomic driver, nouveau has a lot of leftover code that relies on retrieving information regarding the new atomic state from members of drm_encoder and drm_crtc. The first field being used, drm_encoder.crtc, is deprecated for atomic drivers. The second field being used is drm_crtc.state, which is only really sensible to use outside of an atomic modeset. So, add some helpers to lookup the current crtc for a given outp from the atomic state. Then, convert most of the code in dispnv50/disp.c to use said new helper, along with the relevant DRM atomic helpers for retrieving the new encoder/crtc combinations for a new atomic state. Note that we don't get rid of the nouveau_encoder.crtc field entirely for three reasons: - Legacy modesetting for pre-nv50 still uses it - It doesn't cause any locking issues - We need it for the HDA callbacks, as grabbing atomic modesetting locks in those would be a mess.

2021-01-29drm/nouveau/kms/nv50-: s/armh/asyh/ in nv50_msto_atomic_enable()Lyude Paul1-5/+4
I have a strange dejavu feeling that I tried to submit a patch for this in the past, but that it was rejected. I can't remember though, but I'm further convinced this patch is the right thing to do anyway. We label the to-be-committed head state in nv50_msto_atomic_enable() as armh. Normally armh implies a state which is currently armed in hardware. nv50_msto_atomic_enable() is called _after_ drm_atomic_swap_state() however, but before the commit tail ends, which means that said state is not actually armed on hardware. As well - take note that this is the same convention followed in all of the other atomic_enable() callbacks. So, let's correct this to asyh.

Noticed these in both the disable (which we'll be getting rid of in a moment) and the atomic disable callbacks: both callback types check whether or not there's actually a CRTC assigned to the given encoder. However, as ->atomic_disable and ->disable will never be called without a CRTC assigned to the given encoder there's no point in this check. So just remove it.

2021-01-29drm/nouveau/kms/gk104-gp1xx: Fix > 64x64 cursorsLyude Paul2-1/+31
While we do handle the additional cursor sizes introduced in NVE4, it looks like we accidentally broke this when converting over to use Nvidia's display headers. Since we now use NVVAL in dispnv50/head907d.c in order to format the value for the cursor layout and NVD9 only had one byte reserved vs. the 2 bytes reserved in later generations, we end up accidentally stripping the second bit in the cursor layout format parameter - causing us to set the wrong cursor size. This fixes that by adding our own curs_set hook for 917d which uses the NV917D headers.

Commit f844eb485eb056ad3b67e49f95cbc6c685a73db4 introduced a regression for NV50, which lead to visual artifacts, tearing and eventual crashes. In the changes of f844eb485eb056ad3b67e49f95cbc6c685a73db4 only the first line was correctly translated to the new NVIDIA header macros: - PUSH_NVSQ(push, NV827C, 0x0110, 0, - 0x0114, 0); + PUSH_MTHD(push, NV827C, SET_PROCESSING, + NVDEF(NV827C, SET_PROCESSING, USE_GAIN_OFS, DISABLE)); The lower part ("0x0114, 0") was probably omitted by accident.

UEFI/RM no longer use IED scripts from the VBIOS, though they appear to have been updated for use by the x86 VBIOS code, so we should be able to continue using them for the moment. Unfortunately, we require some hacks to do so, as the BeforeLinkTraining IED script became a pointer to an array of scripts instead, without a revbump of the relevant tables. There's also some changes to SOR clock divider fiddling, which are hopefully correct enough that things work as they should. AFAIK, GA100 shouldn't have display, so it hasn't been added.

2021-01-15drm/nouveau/dmaobj/ga10[24]: initial supportBen Skeggs1-0/+2
Appears to be compatible with GV100 code, and not required on GA100, as it shouldn't have display. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2021-01-15drm/nouveau/gpio/ga10[024]: initial supportBen Skeggs4-0/+123
GA100 appears to be compatible with GK104 code, the others have some register moves. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

No VPR scrub. GA102 and GA104 have a new VRAM size detection method. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2021-01-15drm/nouveau/mc/ga10[024]: initial supportBen Skeggs4-0/+79
Fortunately, all the interrupts we need to bring up basic display support are contained in a single leaf register, allowing this basic (but hackish) implementation. There's a bunch more invasive patches to come implementing all this in a better/more complete way, but trying to get a minimal series out first. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2021-01-15drm/nouveau/devinit/ga10[024]: initial supportBen Skeggs6-1/+83
VPLL regs changed a bit. There's more stuff to do around these, but it's less invasive to stick those changes into disp for now. None of that belongs here anymore anyhow - fix that someday. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2021-01-15drm/nouveau/bios/ga10[024]: initial supportBen Skeggs2-0/+6
Forcing PRAMIN-shadowing off for GA100, as it requires display, and we don't know if/where the fuse register for detecting its presence is. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2021-01-15drm/nouveau/pci/ga10[024]: initial supportBen Skeggs1-0/+3

2021-01-15drm/nouveau/core: recognise GA10[024]Ben Skeggs5-3/+36
GA100 hidden behind a module option, as it's not been as well verified since initial bring-up and may need additional changes. There's no display anyway, so this can wait for a bit. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2021-01-15drm/nouveau/kms/nv50-: fix case where notifier buffer is at offset 0Ben Skeggs3-4/+4
VRAM offset 0 is a valid address, triggered on GA102. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
