Factor out tlb and mocs register offset table to fix the issues reported by klocwork, #512 and #550. Mostly, the reason why the klocwork reports these problems is because there can be possbilities for platforms, which have more rings than the ring offset table, to take the dirty data from the stack as the register offset. It results to a random HW register offset writting in this scenairo when doing context switch between vGPUs. After the factoring, the ring offset table of TLB and MOCS should be per platform. v2: - Enable TLB register switch for GEN8. (Zhenyu) Reviewed-by:

When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. Because there is no need to check these functions, a number of local functions can be made to return void to simplify things as nothing can fail.

Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes, in particular in the context in which this code is being used. So, replace the following form: sizeof(*sparse) + (nr_areas * sizeof(*sparse->areas) with: struct_size(sparse, areas, sparse->nr_areas) and so on... Also, notice that variable size is unnecessary, hence it is removed. This code was detected with the help of Coccinelle. Signed-off-by:

Modifying a remote context requires careful serialisation with requests on that context, and that serialisation requires us to take their timeline->mutex. Make it so. Note that while struct_mutex rules, we can't create more than one request in parallel, but that age is soon coming to an end. v2: Though it doesn't affect the current users, contexts may share timelines so check if we already hold the right mutex.

Chris Wilson authored
Currently we use the engine->active.lock to ensure that the request is not retired as we capture the data. However, we only need to ensure that the vma are not removed prior to use acquiring their contents, and since we have already relinquished our stop-machine protection, we assume that the user will not be overwriting the contents before we are able to record them. In order to capture the vma outside of the spinlock, we acquire a reference and mark the vma as active to prevent it from being unbound. However, since it is tricky allocate an entry in the fence tree (doing so would require taking a mutex) while inside the engine spinlock, we use an atomic bit and special case the handling for i915_active_wait. The core benefit is that we can use some non-atomic methods for mapping the device pages, we can remove the slow compression phase out of atomic context (i.e. stop antagonising the nmi-watchdog), and no we longer need large reserves of atomic pages.

Daniele Ceraolo Spurio authored
The way we load the firmwares is the same for both GuC and HuC, the only difference is in the wopcm destination address and the dma flags, so we easily can move the logic to a common function and pass in offset and flags. The only other difference in the uplaod path are some the extra steps that guc does before and after the xfer, but those don't require the guc fw to be pinned in ggtt and can safely be performed before calling the uc_upload function. Note that this patch re-introduces the dma xfer wait for guc loading that was removed with "drm/i915/guc: Propagate the fw xfer timeout". This is not going to slow us down on a successful load (the dma has to complete before fw init can start), but could slightly increase the timeout in case of a fw init error. v2: use _fw variants for uncore accesses (Chris), fix guc_fw status on failed wait. v3: use dev_err and print DMA_CTRL (Chris) Signed-off-by: -

The gt is our new central structure for uc-related code, so we can use that instead of jumping back to i915 via the fw object. Since we have it in the upload function it is easy to pass it through the lower levels of the xfer process instead of continuosly jumping via uc_fw->uc->gt, which will also make things a bit cleaner for the next patch.

We currently track fetch and load status separately, but the 2 are actually sequential in the uc lifetime (fetch must complete before we can attempt the load!). Unifying the 2 variables we can better follow the sequential states and improve our trackng of the uC state. Also, sprinkle some GEM_BUG_ON to make sure we transition correctly between states. v2: rename states, add the running state (Michal), drop some logs in the fetch path (Michal, Chris) v3: re-rename states, extend early status check to all helpers (Michal) Suggested-by: -

Instead of having 2 identical functions for GuC and HuC firmware selection, we can unify the selection logic and just use different lists based on FW type. Note that the revid is not relevant for current blobs, but the upcoming CML will be identified as CFL rev 5, so by considering the revid we're ready for that. v2: rework blob list defs (Michal), add order check (Chris), fuse GuC and HuC lists into one. v3: remove difference between no uC HW and no uC FW, simplify related selection code, check the whole fw list (Michal) Signed-off-by: -
Daniele Ceraolo Spurio authored
There are 2 issues around handling of missing uC support: - We treat lack of uC HW and lack of uC FW definition as 2 different cases, but both of them mean that we don't support the uC on the platform we're running on. - We rely on the modparam to decide if we can take uC paths or not, but we don't sanitize it if it is set incorrectly on platform with no uC support. To fix both of them, unify the 2 cases in a single one and sanitize the modparam on invalid configuration (after printing an error message). The log has been adapted as well, since the user doesn't care why we don't support GuC/HuC (no HW or no FW), just that we do not. Developers can easily find the answer based on the platform, so we can simplify the log. Correcting the modparam has been preferred over failing the load since this is what we usually do for non-supported feature (e.g. the now gone enable_ppgtt would fall back to the highest supported PPGTT mode if the selected one was not available). Note that this patch purposely doesn't change the behavior for platforms that do have uC support, in which case we will still fail if enable_guc is set and the firmware is not available on the system.
