2020-01-15drm/nouveau/ltc/gp10b: Add custom L2 cache implementationThierry Reding5-1/+70
There are extra registers that need to be programmed to make the level 2 cache work on GP10B, such as the stream ID register that is used when an SMMU is used to translate memory addresses. Signed-off-by: Thierry Reding <[email protected]> Signed-off-by: Ben Skeggs <[email protected]>
2020-01-15drm/nouveau/secboot/gm20b,gp10b: Read WPR configuration from GPU registersThierry Reding3-35/+54

2020-01-15drm/nouveau/tegra: Avoid pulsing reset twiceThierry Reding1-6/+6
When the GPU powergate is controlled by a generic power domain provider, the reset will automatically be asserted and deasserted as part of the power-ungating procedure. On some Jetson TX2 boards, doing an additional assert and deassert of the GPU outside of the power-ungate procedure can cause the GPU to go into a bad state where the memory interface can no longer access system memory.

2020-01-15drm/nouveau/fault: Add support for GP10BThierry Reding8-7/+80
There is no BAR2 on GP10B and there is no need to map through BAR2 because all memory is shared between the GPU and the CPU. Add a custom implementation of the fault sub-device that uses nvkm_memory_addr() instead of nvkm_memory_bar2() to return the address of a pinned fault buffer.

2020-01-15drm/nouveau/kms/nv50-: Report possible_crtcs incorrectly on mstos, for nowLyude Paul1-0/+12
This commit is seperate from the previous one to make it easier to revert in the future. Basically, while working on making MSTOs per-head as opposed to per-head-per-connector I discovered these lovely issues: https://gitlab.freedesktop.org/xorg/xserver/merge_requests/277 https://gitlab.gnome.org/GNOME/mutter/issues/759 Note as well that Intel already has a temporary workaround for this in their kernel driver. So, unfortunately we need to follow suit to avoid causing a regression in userspace. Once these issues get fixed, this commit should be reverted.

2020-01-15drm/nouveau/kms/nv50-: Use less encoders by making mstos per-headLyude Paul4-46/+68
Currently, for every single MST capable DRM connector we create a set of fake encoders, one for each possible head. Unfortunately this ends up being a huge waste of encoders. While this currently isn't causing us any problems, it's extremely close to doing so. The ThinkPad P71 is a good example of this. Originally when trying to figure out why nouveau was failing to load on this laptop, I discovered it was because nouveau was creating too many encoders. This ended up being because we were mistakenly creating MST encoders for the eDP port, however we are still extremely close to hitting the encoder limit on this machine as it exposes 1 eDP port and 5 DP ports, resulting in 31 encoders. So while this fix didn't end up being necessary to fix the P71, we still need to implement this so that we avoid hitting the encoder limit for valid display configurations in the event that some machine with more connectors then this becomes available. Plus, we don't want to let good code go to waste :) So, use less encoders by only creating one MSTO per head. Then, attach each new MSTC to each MSTO which corresponds to a head that it's parent DP port is capable of using. This brings the number of encoders we register on the ThinkPad P71 from 31, down to just 15. Yay! Signed-off-by: Lyude Paul <[email protected]> Signed-off-by: Ben Skeggs <[email protected]>
2020-01-15drm/nouveau/kms/nv50-: Remove nv50_mstc_best_encoder()Lyude Paul1-9/+0
When drm_connector_helper_funcs->atomic_best_encoder is defined, ->best_encoder is ignored by the atomic modesetting helpers. That being said, this hook is completely broken anyway - it always returns the first msto for a given mstc, despite the fact it might already be in use. So, just get rid of it. We'll need this in a moment anyway, when we make mstos per-head as opposed to per-connector.

2020-01-09drm/amd/display: Trigger modesets on MST DSC connectorsMikita Lipski1-0/+33

2020-01-09drm/panel: Add driver for Sony ACX424AKP panelLinus Walleij4-0/+568
The Sony ACX424AKP is a command/videomode DSI panel for mobile devices. It is used on the ST-Ericsson HREF520 reference design. We support video mode by default, but it is possible to switch the panel into command mode by using the bool property "dsi-command-mode".

2020-01-09drm/udl: Make udl driver depend on CONFIG_USBThomas Zimmermann1-2/+1
The udl driver for DisplayLink devices depends on support for host-side USB controllers, which is enabled with CONFIG_USB. Plain USB support as given by CONFIG_USB_SUPPORT is not sufficient. This patch changes dependencies for udl to depend on CONFIG_USB, instead of CONFIG_USB_SUPPORT. Users will have to enable CONFIG_USB and select a USB host controller. With this change udl dependencies work the same way as dependencies for PCI drivers.
