Qiang Yu authored
heap buffer is used as output of GP and input of PP for Mali Utgard GPU. Size of heap buffer depends on the task so is a runtime variable. Previously we just create a large enough buffer as heap buffer. Now we add a heap buffer type to be able to increase the backup memory dynamically when GP fail due to lack of heap memory.

Since drm_global_mutex is a true global mutex across devices, we don't want to acquire it unless absolutely necessary. For maintaining the device local open_count, we can use atomic operations on the counter itself, except when making the transition to/from 0. Here, we tackle the easy portion of delaying acquiring the drm_global_mutex for the final release by using atomic_dec_and_mutex_lock(), leaving the global serialisation across the device opens.

Chris Wilson authored
The file is not part of the global drm resource and can be released prior to take the global mutex to drop the open_count (and potentially close) the drm device. As the global mutex is indeed global, not only within the device but across devices, a slow file release mechanism can bottleneck the entire system. However, inside drm_close_helper() there are a number of dev->driver callbacks that take the drm_device as the first parameter... Worryingly some of those callbacks may be (implicitly) depending on the global mutex. v2: Drop the debug message for the open-count, it's included with the drm_file_free() debug message -- and for good measure make that up as reading outside of the mutex. v3: Separate the calling of the filp cleanup outside of drm_global_mutex into a new drm_release_noglobal() hook, so that we can phase the transition. drm/savage relies on the global mutex, and there may be more, so be cautious.

The issues caused by: commit 64e62bdf ("drm/dp_mst: Remove VCPI while disabling topology mgr") Prompted me to take a closer look at how we clear the payload state in general when disabling the topology, and it turns out there's actually two subtle issues here. The first is that we're not grabbing &mgr.payload_lock when clearing the payloads in drm_dp_mst_topology_mgr_set_mst(). Seeing as the canonical lock order is &mgr.payload_lock -> &mgr.lock (because we always want &mgr.lock to be the inner-most lock so topology validation always works), this makes perfect sense. It also means that -technically- there could be racing between someone calling drm_dp_mst_topology_mgr_set_mst() to disable the topology, along with a modeset occurring that's modifying the payload state at the same time. The second is the more obvious issue that Wayne Lin discovered, that we're not clearing proposed_payloads when disabling the topology. I actually can't see any obvious places where the racing caused by the first issue would break something, and it could be that some of our higher-level locks already prevent this by happenstance, but better safe then sorry. So, let's make it so that drm_dp_mst_topology_mgr_set_mst() first grabs &mgr.payload_lock followed by &mgr.lock so that we never race when modifying the payload state. Then, we also clear proposed_payloads to fix the original issue of enabling a new topology with a dirty payload state. This doesn't clear any of the drm_dp_vcpi structures, but those are getting destroyed along with the ports anyway. Changes since v1: * Use sizeof(mgr->payloads[0])/sizeof(mgr->proposed_vcpis[0]) instead - vsyrjala Cc: Sean Paul <sean@poorly.run> Cc: Wayne Lin <Wayne.Lin@amd.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: stable@vger.kernel.org # v4.4+ Signed-off-by:

Explicit management of the GPU's core stacks is only necessary in the case of a broken integration with the PDC. Since there are no known platforms which have such a broken integration let's remove the explicit control from the driver since this apparently causes problems on other platforms and will have a small performance penality. The out of tree mali_kbase driver contains this text regarding controlling the core stack (CONFIGMALI_CORESTACK): Enabling this feature on supported GPUs will let the driver powering on/off the GPU core stack independently without involving the Power Domain Controller. This should only be enabled on platforms which integration of the PDC to the Mali GPU is known to be problematic. This feature is currently only supported on t-Six and t-HEx GPUs. If unsure, say N.

Currently the st7735r driver supports only a single display panel. Prepare for adding support for other display panels by factoring out the display-specific parameters in struct st7735r_cfg. For now, the following parameters can be configured: - Display resolution, - Horizontal/vertical display offsets, - Read-write versus read-only controllers, - RGB versus BGR color component ordering. Rename jd_t18003_t01_pipe_enable() and jd_t18003_t01_pipe_funcs() to st7735r_pipe_enable() resp. st7735r_pipe_funcs(), as they are not really specific to the Jianda JD-T18003-T01 display anymore.

It can be found on e.g. the Renesas YRSK-LCD-PMOD extension board, which comes with various Renesas development kits (e.g. Renesas Starter Kit+ for RZ/A1H[1]). ST7715R and ST7735R are very similar. Their major difference is that the former is restricted to displays of up to 132x132 pixels, while the latter supports displays up to 132x162 pixels.
