* | | | drm/v3d: Introduce a new DRM driver for Broadcom V3D V3.x+Eric Anholt2018-05-031-0/+1

V3D 3.3 introduces an MMU, which means we no longer need CMA or vc4's complicated CL/shader validation scheme. This massively changes the GEM behavior, so I've forked off to a new driver. v2: Mark SUBMIT_CL as needing DRM_AUTH. coccinelle fixes from kbuild test robot. Drop personal git link from MAINTAINERS. Don't double-map dma-buf imported BOs. Add kerneldoc about needing MMU eviction. Drop prime vmap/unmap stubs. Delay mmap offset setup to mmap time. Use drm_dev_init instead of _alloc. Use ktime_get() for wait_bo timeouts. Drop drm_can_sleep() usage, since we don't modeset. Switch page tables back to WC (debug change to coherent had slipped in). Switch drm_gem_object_unreference_unlocked() to drm_gem_object_put_unlocked(). Simplify overflow mem handling by not sharing overflow mem between jobs. v3: no changes v4: align submit_cl to 64 bits (review by airlied), check zero flags in other ioctls.

Since they're non-contig, the scatter-list is huge. 4. imports it into rcar-du, which requires dma-contig memory for scanout. -> On this given platform there's an IOMMU, so in theory this should work. But in practice this failed, because of the huge number of sg entries, even though the IOMMU driver mapped it all into a dma-contig range. With a guest-contig buffer allocated in step 1, this problem doesn't exist. But there's technically no reason to require guest-contig memory for xen buffer sharing using grants. Given all that, the xen-front cma support is not needed and should be removed.

Accompanying backend [1] is implemented as a user-space application and its helper library [2], capable of running as a Weston client or DRM master. Configuration of both backend and frontend is done via Xen guest domain configuration options [3]. Driver limitations: 1. Only primary plane without additional properties is supported. 2. Only one video mode supported which resolution is configured via XenStore. 3. All CRTCs operate at fixed frequency of 60Hz. 1. Implement Xen bus state machine for the frontend driver according to the state diagram and recovery flow from display para-virtualized protocol: xen/interface/io/displif.h. 2. Read configuration values from Xen store according to xen/interface/io/displif.h protocol: - read connector(s) configuration - read buffer allocation mode (backend/frontend) 3. Handle Xen event channels: - create for all configured connectors and publish corresponding ring references and event channels in Xen store, so backend can connect - implement event channels interrupt handlers - create and destroy event channels with respect to Xen bus state 4. Implement shared buffer handling according to the para-virtualized display device protocol at xen/interface/io/displif.h: - handle page directories according to displif protocol: - allocate and share page directories - grant references to the required set of pages for the page directory - allocate xen balllooned pages via Xen balloon driver with alloc_xenballooned_pages/free_xenballooned_pages - grant references to the required set of pages for the shared buffer itself - implement pages map/unmap for the buffers allocated by the backend (gnttab_map_refs/gnttab_unmap_refs) 5. Implement kernel modesetiing/connector handling using DRM simple KMS helper pipeline: - implement KMS part of the driver with the help of DRM simple pipepline helper which is possible due to the fact that the para-virtualized driver only supports a single (primary) plane: - initialize connectors according to XenStore configuration - handle frame done events from the backend - create and destroy frame buffers and propagate those to the backend - propagate set/reset mode configuration to the backend on display enable/disable callbacks - send page flip request to the backend and implement logic for reporting backend IO errors on prepare fb callback - implement virtual connector handling: - support only pixel formats suitable for single plane modes - make sure the connector is always connected - support a single video mode as per para-virtualized driver configuration 6. Implement GEM handling depending on driver mode of operation: depending on the requirements for the para-virtualized environment, namely requirements dictated by the accompanying DRM/(v)GPU drivers running in both host and guest environments, number of operating modes of para-virtualized display driver are supported: - display buffers can be allocated by either frontend driver or backend - display buffers can be allocated to be contiguous in memory or not Note! Frontend driver itself has no dependency on contiguous memory for its operation. 6.1. Buffers allocated by the frontend driver. The below modes of operation are configured at compile-time via frontend driver's kernel configuration. 6.1.1. Front driver configured to use GEM CMA helpers This use-case is useful when used with accompanying DRM/vGPU driver in guest domain which was designed to only work with contiguous buffers, e.g. DRM driver based on GEM CMA helpers: such drivers can only import contiguous PRIME buffers, thus requiring frontend driver to provide such. In order to implement this mode of operation para-virtualized frontend driver can be configured to use GEM CMA helpers. 6.1.2. Front driver doesn't use GEM CMA If accompanying drivers can cope with non-contiguous memory then, to lower pressure on CMA subsystem of the kernel, driver can allocate buffers from system memory. Note! If used with accompanying DRM/(v)GPU drivers this mode of operation may require IOMMU support on the platform, so accompanying DRM/vGPU hardware can still reach display buffer memory while importing PRIME buffers from the frontend driver. 6.2. Buffers allocated by the backend This mode of operation is run-time configured via guest domain configuration through XenStore entries. For systems which do not provide IOMMU support, but having specific requirements for display buffers it is possible to allocate such buffers at backend side and share those with the frontend. For example, if host domain is 1:1 mapped and has DRM/GPU hardware expecting physically contiguous memory, this allows implementing zero-copying use-cases. Note, while using this scenario the following should be considered: a) If guest domain dies then pages/grants received from the backend cannot be claimed back b) Misbehaving guest may send too many requests to the backend exhausting its grant references and memory (consider this from security POV). Note! Configuration options 1.1 (contiguous display buffers) and 2 (backend allocated buffers) are not supported at the same time. 7. Handle communication with the backend: - send requests and wait for the responses according to the displif protocol - serialize access to the communication channel - time-out used for backend communication is set to 3000 ms - manage display buffers shared with the backend [1] https://github.com/xen-troops/displ_be [2] https://github.com/xen-troops/libxenbe [3] https://xenbits.xen.org/gitweb/?p=xen.git;a=blob;f=docs/man/xl.cfg.pod.5.in;h=a699367779e2ae1212ff8f638eff0206ec1a1cc9;hb=refs/heads/master#l1257 Signed-off-by: Oleksandr Andrushchenko <oleksandr_andrushchenko@epam.com> Reviewed-by: Boris Ostrovsky <boris.ostrovsky@oracle.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20180403112317.28751-2-andr2000@gmail.com

Also, since Ville remove the void* usage it's a good opportunity to give the driver private stuff some tlc on the doc front. Finally try to explain why the "let's just subclass drm_atomic_state" approach wasn't the greatest, and annotate all those functions as deprecated in favour of more standardized driver private states. Also note where we could/should extend driver private states going forward (atm neither locking nor synchronization is handled in core/helpers, which isn't really all that great). v2: Spelling and phrasing improvements (Alex, DK).

So at least on x86, we need a quirk table for this. This commit adds a DMI based quirk table which is initially populated with 5 such devices: Asus T100HA, GPD Pocket, GPD win, I.T.Works TW891 and the VIOS LTH17. This quirk table will be used by the drm code to let userspace know that the display is not mounted upright inside the devices case through a new panel orientation drm-connector property, as well as to tell fbcon to rotate the console so that it shows the right way up. Changes in v5: -Add a kernel-doc comment documenting drm_get_panel_orientation_quirk() -Remove board_* matches from the dmi-matches for the VIOS LTH17 laptop, keeping only the (identical) sys_vendor and product_name matches. This is necessary because an older version of the bios has board_vendor set to VOIS instead of VIOS Changes in v6: -Add reference to added kernel-docs in Documentation/gpu/drm-kms-helpers.rst Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20171125193553.23986-3-hdegoede@redhat.com

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. ...

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. ...
