Using the generic extension from the previous patch, a specific multisync extension enables more than one in/out binary syncobj per job submission. Arrays of syncobjs are set in struct drm_v3d_multisync, that also cares of determining the stage for sync (wait deps) according to the job queue. v2: - subclass the generic extension struct (Daniel) - simplify adding dependency conditions to make understandable (Iago) v3: - fix conditions to consider single or multiples in/out_syncs (Iago) - remove irrelevant comment (Iago) Signed-off-by:

Add support to attach generic extensions on job submission. This patch is third prep work to enable multiple syncobjs on job submission. With this work, when the job submission interface needs to be extended to accommodate a new feature, we will use a generic extension struct where an id determines the data type to be pointed. The first application is to enable multiples in/out syncobj (next patch), but the base is already done for future features. Therefore, to attach a new feature, a specific extension struct should subclass drm_v3d_extension and update the list of extensions in a job submission. v2: - remove redundant elements to subclass struct (Daniel) v3: - add comment for v3d_get_extensions Signed-off-by:

Move job memory allocation to v3d_job_init function. This aim to facilitate error handling in job initialization, since cleanup steps are similar for all (struct v3d_job)-based types of job involved in a command submission. To generalize v3d_job_init(), this change takes into account that all job structs have the first element a struct v3d_job (bin, render, tfu, csd) or it is a v3d_job itself (clean_job) for pointer casting. v3: - explicitly init job as NULL (Iago) - fix pm failure handling on v3_job_init (Iago) Suggested-by:

This can be used to create a separate DRM file description, thus creating a new GEM handle namespace. My use-case is wlroots. The library splits responsibilities between separate components: the GBM allocator creates buffers, the GLES2 renderer uses EGL to import them and render to them, the DRM backend imports the buffers and displays them. wlroots has a modular architecture, and any of these components can be swapped and replaced with something else. For instance, the pipeline can be set up so that the DRM dumb buffer allocator is used instead of GBM and the Pixman renderer is used instead of GLES2. Library users can also replace any of these components with their own custom one. DMA-BUFs are used to pass buffer references across components. We could use GEM handles instead, but this would result in pain if multiple GPUs are in use: wlroots copies buffers across GPUs as needed. Importing a GEM handle created on one GPU into a completely different GPU will blow up (fail at best, mix unrelated buffers otherwise). Everything is fine if all components use Mesa. However, this isn't always desirable. For instance when running with DRM dumb buffers and the Pixman software renderer it's unfortunate to depend on GBM in the DRM backend just to turn DMA-BUFs into FB IDs. GBM loads Mesa drivers to perform an action which has nothing driver-specific. Additionally, drivers will fail the import if the 3D engine can't use the imported buffer, for instance amdgpu will refuse to import DRM dumb buffers [1]. We might also want to be running with a Vulkan renderer and a Vulkan allocator in the future, and GBM wouldn't be welcome in this setup. To address this, GBM can be side-stepped in the DRM backend, and can be replaced with drmPrimeFDToHandle calls. However because of GEM handle reference counting issues, care must be taken to avoid double-closing the same GEM handle. In particular, it's not possible to share a DRM FD with GBM or EGL and perform some drmPrimeFDToHandle calls manually. So wlroots needs to re-open the DRM FD to create a new GEM handle namespace. However there's no guarantee that the file-system permissions will be set up so that the primary FD can be opened by the compsoitor. On modern systems seatd or logind is a privileged process responsible for doing this, and other processes aren't expected to do it. For historical reasons systemd still allows physically logged in users to open primary DRM nodes, but this doesn't work on non-systemd setups and it's desirable to lock them down at some point. Some might suggest to open the render node instead of re-opening the primary node. However some systems don't have a render node at all (e.g. no GPU, or a split render/display SoC). Solutions to this issue have been discussed in [2]. One solution would be to open the magic /proc/self/fd/<fd> file, but it's a Linux-specific hack (wlroots supports BSDs too). Another solution is to add support for re-opening a DRM primary node to seatd/logind, but they don't support it now and really haven't been designed for this (logind would need to grow a completely new API, because it assumes unique dev_t IDs). Also this seems like pushing down a kernel limitation to user-space a bit too hard. Another solution is to allow creating empty DRM leases. The lessee FD would have its own GEM handle namespace, so wouldn't conflict wth GBM/EGL. It would have the master bit set, but would be able to manage zero resources. wlroots doesn't intend to share this FD with any other process. All in all IMHO that seems like a pretty reasonable solution to the issue at hand. Note, I've discussed with Jonas Ådahl and Mutter plans to adopt a similar design in the future. Example usage in wlroots is available at [3]. IGT test available at [4].

Daniel pointed me towards this function and there are multiple obvious problems in the implementation. First of all the retry loop is not working as intended. In general the retry makes only sense if you grab the reference first and then check the sequence values. Then we should always also wait for the exclusive fence. It's also good practice to keep the reference around when installing callbacks to fences you don't own. And last the whole implementation was unnecessary complex and rather hard to understand which could lead to probably unexpected behavior of the IOCTL. Fix all this by reworking the implementation from scratch. Dropping the whole RCU approach and taking the lock instead. Only mildly tested and needs a thoughtful review of the code. Pushing through drm-misc-next to avoid merge conflicts and give the code another round of testing. v2: fix the reference counting as well v3: keep the excl fence handling as is for stable v4: back to testing all fences, drop RCU v5: handle in and out separately v6: add missing clear of events v7: change coding style as suggested by Michel, drop unused variables Signed-off-by:

In commit: commit 667a50db Author: Thomas Hellstrom <thellstrom@vmware.com> Date: Fri Jan 3 11:17:18 2014 +0100 drm/ttm: Refuse to fault (prime-) imported pages we introduced the restriction that imported pages should not be directly mappable through TTM(this also extends to userptr). In the next patch we want to introduce a shmem_tt backend, which should follow all the existing rules with TTM_PAGE_FLAG_EXTERNAL, since it will need to handle swapping itself, but with the above mapping restriction lifted. v2(Christian): - Don't OR together EXTERNAL and EXTERNAL_MAPPABLE in the definition of EXTERNAL_MAPPABLE, just leave it the caller to handle this correctly, otherwise we might encounter subtle issues.
