Some usb type-c dongle use irq_hpd request to perform device connection and disconnection. This patch add handling of both connection and disconnection are based on the state of hpd_state and sink_count. Changes in V2: -- add dp_display_handle_port_ststus_changed() -- fix kernel test robot complaint Changes in V3: -- add encoder_mode_set into struct dp_display_private Reported-by: kernel test robot <lkp@intel.com> Fixes: 26b8d66a ("drm/msm/dp: promote irq_hpd handle to handle link training correctly") Tested-by: Stephen Boyd <swboyd@chromium.org> Signed-off-by: Kuogee Hsieh <khsieh@codeaurora.org> Signed-off-by: Rob Clark <robdclark@chromium.org>

Update the qos remap only if the client type changes for the plane. This will avoid unnecessary register programming and also avoid log spam from the dpu_vbif_set_qos_remap() function. changes in v2: - get rid of the dirty flag and simplify the logic to call _dpu_plane_set_qos_remap() Signed-off-by: Abhinav Kumar <abhinavk@codeaurora.org> Signed-off-by: Rob Clark <robdclark@chromium.org>

Kalyan Thota authored
In case of panels with low vertical back porch, the prefill bw requirement will be high as we will have less time(vbp+pw) to fetch and fill the hw latency buffers before start of first line in active period. For ex: Say hw_latency_line_buffers = 24, and if blanking vbp+pw = 10 Here we need to fetch 24 lines of data in 10 line times. This will increase the bw to the ratio of linebuffers to blanking. DPU hw can also fetch data during vertical front porch provided interface prefetch is enabled. Use vfp in the prefill calculation as dpu driver enables prefetch if the blanking is not sufficient to fill the latency lines.

GPU targets with an MMU-500 attached have a slightly different process for enabling system cache. Use the compatible string on the IOMMU phandle to see if an MMU-500 is attached and modify the programming sequence accordingly.

The last level system cache can be partitioned to 32 different slices of which GPU has two slices preallocated. One slice is used for caching GPU buffers and the other slice is used for caching the GPU SMMU pagetables. This talks to the core system cache driver to acquire the slice handles, configure the SCID's to those slices and activates and deactivates the slices upon GPU power collapse and restore. Some support from the IOMMU driver is also needed to make use of the system cache to set the right TCR attributes. GPU then has the ability to override a few cacheability parameters which it does to override write-allocate to write-no-allocate as the GPU hardware does not benefit much from it. DOMAIN_ATTR_IO_PGTABLE_CFG is another domain level attribute used by the IOMMU driver for pagetable configuration which will be used to set a quirk initially to set the right attributes to cache the hardware pagetables into the system cache.

Add a new iommu domain attribute DOMAIN_ATTR_IO_PGTABLE_CFG for pagetable configuration which initially will be used to set quirks like for system cache aka last level cache to be used by client drivers like GPU to set right attributes for caching the hardware pagetables into the system cache and later can be extended to include other page table configuration data.

In situations where the GPU is mostly idle, all or nearly all buffer objects will be in the inactive list. But if the system is under memory pressure (from something other than GPU), we could still get a lot of shrinker calls. Which results in traversing a list of thousands of objs and in the end finding nothing to shrink. Which isn't so efficient. Instead split the inactive_list into two lists, one inactive objs which are shrinkable, and a second one for those that are not. This way we can avoid traversing objs which we know are not shrinker candidates. v2: Fix inverted logic think-o Signed-off-by: Rob Clark <robdclark@chromium.org>

Just because a obj is active, if the vmap_count is zero, we can still tear down the vmap. Signed-off-by: Rob Clark <robdclark@chromium.org>

Previously we only held obj lock in the _active_get() path, and relied on atomic_dec_return() to not be racy in the _active_put() path where obj lock was not held. But this is a false sense of security. Unlike obj lifetime refcnt, where you do not expect to *increase* the refcnt after the last put (which would mean that something has gone horribly wrong with the object liveness reference counting), the active_count can increase again from zero. Racing _active_put()s and _active_get()s could leave the obj on the wrong mm list. But in the retire path, immediately after the _active_put(), the _unpin_iova() would acquire obj lock. So just move the locking earlier and rely on that to protect obj->active_count. Fixes: c5c1643c ("drm/msm: Drop struct_mutex from the retire path") Signed-off-by: Rob Clark <robdclark@chromium.org>

For sinks that do not support audio, there is no need to notify audio subsystem of the connection event. This will make sure that audio routes only to the primary display when connected to such sinks. changes in v2: - Added fixes tag - Removed nested if condition and removed usage of global pointer Fixes: d13e36d7 ("drm/msm/dp: add audio support for Display Port on MSM") Signed-off-by: Abhinav Kumar <abhinavk@codeaurora.org> Signed-off-by: Rob Clark <robdclark@chromium.org>

Some dongle will not clear LINK_STATUS_UPDATED bit after DPCD read which cause link training failed. This patch just read 6 bytes of DPCD link status from sink and return without checking LINK_STATUS_UPDATED bit. Only 8 bits are used to represent link rate at sinker DPCD. The really link rate is 2.7Mb times the 8 bits value. For example, 0x0A at DPCD is equal to 2.7Gb (10 * 2.7Mb). This patch also convert 8 bits value of DPCD to really link rate to fix worng link rate error during phy compliance test.

DP compo phy have to be enable to start link training. When link training failed phy need to be disabled so that next link traning can be proceed smoothly at next plug in. This patch de-initialize mainlink to disable phy if link training failed. This prevent system crash due to disp_cc_mdss_dp_link_intf_clk stuck at "off" state. This patch also perform checking power_on flag at dp_display_enable() and dp_display_disable() to avoid crashing when unplug cable while display is off.
