2022-07-27drm/nouveau/disp: collapse nv50_disp into nvkm_dispBen Skeggs1-6/+6
Dump of one struct's members into another, with a couple of list renames because of collisions. Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Reviewed-by: Lyude Paul <lyude@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2022-07-27drm/nouveau/disp: collapse nvkm_dp into nvkm_outpBen Skeggs1-3/+1
There should be no changes to code here other than modifying the dereferences. Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Reviewed-by: Lyude Paul <lyude@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2020-07-24drm/nouveau/disp/gm200-: remove 'head' parameter from nvkm_ior_func.hdmi.scdc()Ben Skeggs1-2/+1
It's no longer required. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2020-06-04drm/nouveau/disp: provide hint to OR allocation about HDA requirementsBen Skeggs1-2/+2
Will be used by a subsequent commit to influence SOR allocation policy. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2020-05-22drm/nouveau/disp/hda/gt215-: pass head to nvkm_ior.hda.eld()Ben Skeggs1-1/+1
We're going to use the bound head to select HDA device entry. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2018-10-11drm/nouveau/disp: add a way to configure scrambling/tmds for hdmi 2.0Ilia Mirkin1-2/+8
High pixel clocks are required to use a 40 TMDS divider instead of 10, and even low ones may optionally use scrambling depending on device support. Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2018-05-18drm/nouveau/disp/nv50-: merge handling of pio and dma channelsBen Skeggs1-1/+1
Unnecessarily complicated, and a barrier to cleanly supporting Volta. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2018-05-18drm/nouveau/disp/nv50-: simplify definiton of core channelsBen Skeggs1-22/+1
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2018-05-18drm/nouveau/disp/nv50-: simplify definition of cursor channelsBen Skeggs1-22/+1

2018-05-18drm/nouveau/disp/nv50-: simplify definition of base channelsBen Skeggs1-1/+1
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2018-05-18drm/nouveau/disp/nv50-: simplify definition of overlay immediate channelsBen Skeggs1-1/+1
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2018-05-18drm/nouveau/disp/nv50-: simplify definition of overlay channelsBen Skeggs1-1/+22
Introduces a new method of defining channels available from the display, common to all channel types, allowing for more flexibility in available channel types/counts, and reducing the amount of boiler-plate required. This will be required to support Volta. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2018-05-18drm/nouveau/disp/nv50-: initialise from the engine, rather than the user objectBen Skeggs1-120/+0
Engines are initialised on an as-needed basis, so this results in the same behaviour, whilst allowing us to simplify things a bit. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2018-05-18drm/nouveau/disp/nv50-: fetch mask of available piors during oneinitBen Skeggs1-1/+1

2018-05-18drm/nouveau/disp/nv50-: fetch mask of available dacs during oneinitBen Skeggs1-1/+1

2017-06-16drm/nouveau/disp/nv50-: implement a common supervisor 2.2Ben Skeggs1-0/+1
This makes use of all the additional routing and state added in previous commits, making it possible to deal with GM20x macro link routing, while also sharing code between the NV50 and GF119 implementations. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/disp: introduce acquire/release display path methodsBen Skeggs1-0/+22
These exist to give NVKM information on the set of display paths that the DD needs to be active at any given time. Previously, the supervisor attempted to determine this solely from OR state, but there's a few configurations where this information on its own isn't enough to determine the specific display paths in question: - ANX9805, where the PIOR protocol for both DP and TMDS is TMDS. - On a device using DCB Switched Outputs. - On GM20x and newer, with a crossbar between the SOR and macro links. After this commit, the DD tells NVKM *exactly* which display path it's attempting a modeset on. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/disp/gf119-: port OR DP VCPI control to nvkm_iorBen Skeggs1-5/+6

2017-06-16drm/nouveau/disp/gt215-: port HDA ELD controls to nvkm_iorBen Skeggs1-4/+32

2017-06-16drm/nouveau/disp/g84-: port OR HDMI control to nvkm_iorBen Skeggs1-3/+39

2017-06-16drm/nouveau/disp/nv50-: port OR manual sink detection to nvkm_iorBen Skeggs1-2/+17
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/disp/nv50-: port OR power state control to nvkm_iorBen Skeggs1-9/+16
Also removes the user-facing methods to these controls, as they're not currently utilised by the DD anyway. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/disp/dp: train link only when actively displaying an imageBen Skeggs1-6/+2
This essentially (unless the link becomes unstable and needs to be re-trained) gives us a single entry-point to link training, during supervisor handling, where we can ensure all routing is up to date. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/disp/dp: remove DP_PWR methodBen Skeggs1-24/+0
This hasn't been used since atomic. We may want to re-implement "fast" DPMS at some point, but for now, this just gets in the way. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/disp: common implementation of scanoutpos method in nvkm_headBen Skeggs1-47/+15
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/disp: introduce object to track per-head functions/stateBen Skeggs1-10/+12
Primarily intended as a way to pass per-head state around during supervisor handling, and share logic between NV50/GF119. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2017-06-16drm/nouveau/disp: rename nvkm_output to nvkm_outpBen Skeggs1-2/+1
This isn't technically "output", but, "display/output path". Not all users of nvkm_output have been changed here. The remaining ones belong to code that's disappearing in upcoming commits. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-11-17drm/nouveau/disp/nv50-: specify ctrl/user separately when constructing classesBen Skeggs1-2/+2

2016-11-07drm/nouveau/disp/dp: remove workqueue for link trainingBen Skeggs1-1/+1
There haven't been any callers from an atomic context for a while now, so let's remove the extra complexity. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2016-11-07drm/nouveau: mark symbols static where possibleBaoyou Xie1-1/+1
We get a few warnings when building kernel with W=1: drivers/gpu/drm/nouveau/nvkm/subdev/bios/fan.c:29:1: warning: no previous prototype for 'nvbios_fan_table' [-Wmissing-prototypes] drivers/gpu/drm/nouveau/nvkm/subdev/bios/fan.c:56:1: warning: no previous prototype for 'nvbios_fan_entry' [-Wmissing-prototypes] drivers/gpu/drm/nouveau/nvkm/subdev/clk/gt215.c:184:1: warning: no previous prototype for 'gt215_clk_info' [-Wmissing-prototypes] drivers/gpu/drm/nouveau/nvkm/subdev/fb/ramgt215.c:99:1: warning: no previous prototype for 'gt215_link_train_calc' [-Wmissing-prototypes] drivers/gpu/drm/nouveau/nvkm/subdev/fb/ramgt215.c:153:1: warning: no previous prototype for 'gt215_link_train' [-Wmissing-prototypes] drivers/gpu/drm/nouveau/nvkm/subdev/fb/ramgt215.c:271:1: warning: no previous prototype for 'gt215_link_train_init' [-Wmissing-prototypes] .... In fact, both functions are only used in the file in which they are declared and don't need a declaration, but can be made static. So this patch marks these functions with 'static'.
