2019-07-23drm/tinydrm: Move tinydrm_spi_transfer()Noralf Trønnes1-3/+0
This is only used by mipi-dbi drivers so move it there. The reason this isn't moved to the SPI subsystem is that it will in a later patch pass a dummy rx buffer for SPI controllers that need this. Low memory boards (64MB) can run into a problem allocating such a "large" contiguous buffer on every transfer after a long up time. This leaves a very specific use case, so we'll keep the function here. mipi-dbi will first go through a refactoring though, before this will be done. Remove SPI todo entry now that we're done with the tinydrm.ko SPI code. v2: Drop moving the mipi_dbi_spi_init() declaration (Sam) Cc: David Lechner <david@lechnology.com> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Acked-by: : David Lechner <david@lechnology.com> Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Link: https://patchwork.freedesktop.org/patch/msgid/20190719155916.62465-8-noralf@tronnes.org

2019-06-11drm/fb-helper: Remove drm_fb_helper_connectorNoralf Trønnes1-0/+4
All drivers add all their connectors so there's no need to keep around an array of available connectors. Instead we just put the useable (not writeback) connectors in a temporary array using drm_client_for_each_connector_iter() everytime we probe the outputs. Other places where it's necessary to look at the connectors, we just iterate over them using the same iterator function. Rename functions which signature is changed since they will be moved to drm_client in a later patch. v6: Improve commit message (Sam Ravnborg) Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20190608152657.36613-2-noralf@tronnes.org
2019-06-04drm/fb-helper: Remove drm_fb_helper_crtcNoralf Trønnes1-0/+3
struct drm_fb_helper_crtc is now just a wrapper around drm_mode_set so use that directly instead and attach it as a modeset array onto drm_client_dev. drm_fb_helper will use this array to store its modesets which means it will always initialize a drm_client, but it will not register the client (callbacks) unless it's the generic fbdev emulation. Code will later be moved to drm_client, so add code there in a new file drm_client_modeset.c with MIT license to match drm_fb_helper.c. The modeset connector array size is hardcoded for the cloned case to avoid having to pass in a value from the driver. A value of 8 is chosen to err on the safe side. This means that the max connector argument for drm_fb_helper_init() and drm_fb_helper_fbdev_setup() isn't used anymore, a todo entry for this is added. In pan_display_atomic() restore_fbdev_mode_force() is used instead of restore_fbdev_mode_atomic() because that one will later become internal to drm_client_modeset.

2019-05-14drm/fb-helper: Avoid race with DRM userspaceNoralf Trønnes1-0/+8
drm_fb_helper_is_bound() is used to check if DRM userspace is in control. This is done by looking at the fb on the primary plane. By the time fb-helper gets around to committing, it's possible that the facts have changed. Avoid this race by holding the drm_device->master_mutex lock while committing. When DRM userspace does its first open, it will now wait until fb-helper is done. The helper will stay away if there's a master. Two igt tests fail with the new 'bail out if master' rule. Work around this by relaxing this rule for drm_fb_helper_restore_fbdev_mode_unlocked() until the tests have been fixed. Add todo entry for this. Locking rule: Always take the fb-helper lock first. v5: drm_fb_helper_restore_fbdev_mode_unlocked(): Use restore_fbdev_mode_force() v2: - Remove drm_fb_helper_is_bound() (Daniel Vetter) - No need to check fb_helper->dev->master in drm_fb_helper_single_fb_probe(), restore_fbdev_mode() has the check.

This adds an optional function table on GEM objects. The main benefit is for drivers that support more than one type of memory (shmem,vram,cma) for their buffers depending on the hardware it runs on. With the callbacks attached to the GEM object itself, it is easier to have core helpers for the the various buffer types.

Pull amdgpu DC display code for Vega from Dave Airlie: "This is the pull request for the AMD DC (display code) layer which is a requirement to program the display engines on the new Vega and Raven based GPUs. It also contains support for all amdgpu supported GPUs (CIK, VI, Polaris), which has to be enabled. It is also a kms atomic modesetting compatible driver (unlike the current in-tree display code). I've kept it separate from drm-next because it may have some things that cause you to reject it. Background story: AMD have an internal team creating a shared OS codebase for display at hw bring up time using information from their hardware teams. This process doesn't lead to the most Linux friendly/looking code but we have worked together on cleaning a lot of it up and dealing with sparse/smatch/checkpatch, and having their team internally adhere to Linux coding standards. This tree is a complete history rebased since they started opening it, we decided not to squash it down as the history may have some value. Some of the commits therefore might not reach kernel standards, and we are steadily training people in AMD to better write commit msgs. There is a major bunch of generated bandwidth calculation and verification code that comes from their hardware team. On Vega and before this is float calculations, on Raven (DCN10) this is double based. They do the required things to do FP in the kernel, and I could understand this might raise some issues. Rewriting the bandwidth would be a major undertaken in reverification, it's non-trivial to work out if a display can handle the complete set of mode information thrown at it. Future story: There is a TODO list with this, and it address most of the remaining things that would be nice to refine/remove. The DCN10 code is still under development internally and they push out a lot of patches quite regularly and are supporting this code base with their display team. I think we've reached the point where keeping it out of tree is going to motivate distributions to start carrying the code, so I'd prefer we get it in tree. I think this code is slightly better than STAGING quality but not massively so, I'd really like to see that float/double magic gone and fixed point used, but AMD don't seem to think the accuracy and revalidation of the code is worth the effort" * tag 'drm-for-v4.15-amd-dc' of git://people.freedesktop.org/~airlied/linux: (1110 commits) drm/amd/display: fix MST link training fail division by 0 drm/amd/display: Fix formatting for null pointer dereference fix drm/amd/display: Remove dangling planes on dc commit state drm/amd/display: add flip_immediate to commit update for stream drm/amd/display: Miss register MST encoder cbs drm/amd/display: Fix warnings on S3 resume drm/amd/display: use num_timing_generator instead of pipe_count drm/amd/display: use configurable FBC option in dm drm/amd/display: fix AZ clock not enabled before program AZ endpoint amdgpu/dm: Don't use DRM_ERROR in amdgpu_dm_atomic_check amd/display: Fix potential null dereference in dce_calcs.c amdgpu/dm: Remove unused forward declaration drm/amdgpu: Remove unused dc_stream from amdgpu_crtc amdgpu/dc: Fix double unlock in amdgpu_dm_commit_planes amdgpu/dc: Fix missing null checks in amdgpu_dm.c amdgpu/dc: Fix potential null dereferences in amdgpu_dm.c amdgpu/dc: fix more indentation warnings amdgpu/dc: handle allocation failures in dc_commit_planes_to_stream. amdgpu/dc: fix indentation warning from smatch. amdgpu/dc: fix non-ansi function decls. ...

into drm-next Initial pull request for DC support. We've completed a substantial amount of the cleanup and restructuring in our TODO. There are a few additional cleanups that we are continuing to work on, but I don't think there are any showstoppers remaining. We've tried to maintain most of the history for bisect purposes. Harry made sure all the commits build. We've enabled DC for vega10 and Raven. Pre-vega10 parts can be enabled via module parameter (amdgpu.dc=1), but are not enabled by default at this point until we get further testing upstream. This code provides atomic modesetting support for DCE8 (CIK), DCE10 (Tonga, Fiji), DCE11 (CZ, ST, Polaris), DCE12 (vega10), and DCN1 (RV) including HDMI and DP audio, DP MST, and many other advanced display features. + Latest cleanups for DC from you and Harry. Note that there is some flickering on some older asics with this branch due to a regression in powerplay that has already been fixed and will be included in my next non-DC pull request next week. * 'drm-next-4.15-dc' of git://people.freedesktop.org/~agd5f/linux: (897 commits) amdgpu/dc: use kref for dc_state. amdgpu/dc: convert dc_sink to kref. amdgpu/dc: convert dc_stream_state to kref. amdgpu/dc: use kref for dc_plane_state. amdgpu/dc: convert dc_gamma to kref reference counting. amdgpu/dc: convert dc_transfer to use a kref. amdgpu/dc: kill a bunch of dead code. amdgpu/dc: set a bunch of functions to static. amdgpu/dc: kill some deadcode in dc core. amdgpu/dc: fix indentation on a couple of returns. amdgpu/dm: don't use after free. amdgpu/dc: kfree already checks for NULL. amdgpu/dc: fix a bunch of misc whitespace. amdgpu/dc: drop hw_sequencer_types.h amdgpu/dc: drop dce110_types.h amdgpu/dc: use kernel ilog2 for log_2. amdgpu/dc: don't memset after kzalloc. amdgpu/dc: inline dal grph object id functions. amdgpu/dc: inline dml_round_to_multiple amdgpu/dc: rename bios get_image symbol to something more searchable. ...
