Reuse the 8b/10b link training delay helpers. Functionally this skips the check for invalid values for DPCD 1.4 and later at clock recovery delay (as it's a fixed delay and bypasses the rd_interval) but the same value will be checked and invalid values reported at channel equalization. Reviewed-by:

The link training delays are different and/or available in different DPCD offsets depending on: - Clock recovery vs. channel equalization - DPRX vs. LTTPR - 128b/132b vs. 8b/10b - DPCD 1.4+ vs. earlier Add helpers to get the correct delays in us, reading DPCD if necessary. This is more straightforward than trying to retrofit the existing helpers to take 128b/132b into account. Having to pass in the DPCD receiver cap field seems unavoidable, because reading it involves checking the revision and reading extended receiver cap. So unfortunately the interface is mixed cached and read as needed. v2: Remove delay_us < 0 check and the whole local var (Ville) Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

The helper function devm_add_action_or_reset() will internally call devm_add_action(), and if devm_add_action() fails then it will execute the action mentioned and return the error code. So use devm_add_action_or_reset() instead of devm_add_action() to simplify the error handling, reduce the code. Signed-off-by:

Abstract the complexity of iterating over all the fences in a dma_resv object. The new loop handles the whole RCU and retry dance and returns only fences where we can be sure we grabbed the right one. v2: fix accessing the shared fences while they might be freed, improve kerneldoc, rename _cursor to _iter, add dma_resv_iter_is_exclusive, add dma_resv_iter_begin/end v3: restructor the code, move rcu_read_lock()/unlock() into the iterator, add dma_resv_iter_is_restarted() v4: fix NULL deref when no explicit fence exists, drop superflous rcu_read_lock()/unlock() calls. v5: fix typos in the documentation v6: fix coding error when excl fence is NULL v7: one more logic fix v8: fix index check in dma_resv_iter_is_exclusive() Signed-off-by: -

In the commit bac9c294 ("drm/edid: Break out reading block 0 of the EDID") I broke out reading the base block of the EDID to its own function. Unfortunately, when I did that I messed up the handling when drm_edid_is_zero() indicated that we had an EDID that was all 0x00 or when we went through 4 loops and didn't get a valid EDID. Specifically I needed to pass the broken EDID to connector_bad_edid() but now I was passing an error-pointer. Let's re-jigger things so we can pass the bad EDID in properly. Fixes: bac9c294 ("drm/edid: Break out reading block 0 of the EDID") Reported-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:
