[PATCH v2] drm/dp_mst: correct the shifting in DP_REMOTE_I2C_READ
by Wayne Lin 06 Jan '20

06 Jan '20

[Why] According to DP spec, it should shift left 4 digits for NO_STOP_BIT in REMOTE_I2C_READ message. Not 5 digits. In current code, NO_STOP_BIT is always set to zero which means I2C master is always generating a I2C stop at the end of each I2C write transaction while handling REMOTE_I2C_READ sideband message. This issue might have the generated I2C signal not meeting the requirement. Take random read in I2C for instance, I2C master should generate a repeat start to start to read data after writing the read address. This issue will cause the I2C master to generate a stop-start rather than a re-start which is not expected in I2C random read. [How] Correct the shifting value of NO_STOP_BIT for DP_REMOTE_I2C_READ case in drm_dp_encode_sideband_req().

[PATCH] drm/hisilicon: Checked the resolution is valid before connector

[PATCH] drm/dp_mst: clear time slots for ports invalid
by Wayne Lin 06 Jan '20

06 Jan '20

[Why] When change the connection status in a MST topology, mst device which detect the event will send out CONNECTION_STATUS_NOTIFY messgae. e.g. src-mst-mst-sst => src-mst (unplug) mst-sst Currently, under the above case of unplugging device, ports which have been allocated payloads and are no longer in the topology still occupy time slots and recorded in proposed_vcpi[] of topology manager. If we don't clean up the proposed_vcpi[], when code flow goes to try to update payload table by calling drm_dp_update_payload_part1(), we will fail at checking port validation due to there are ports with proposed time slots but no longer in the mst topology. As the result of that, we will also stop updating the DPCD payload table of down stream port. [How] While handling the CONNECTION_STATUS_NOTIFY message, add a detection to see if the event indicates that a device is unplugged to an output port. If the detection is true, then iterrate over all proposed_vcpi[] to see whether a port of the proposed_vcpi[] is still in the topology or not. If the port is invalid, set its num_slots to 0. Thereafter, when try to update payload table by calling drm_dp_update_payload_part1(), we can successfully update the DPCD payload table of down stream port and clear the proposed_vcpi[] to NULL.

[PATCH] drm/dp_mst: Avoid NULL pointer dereference

[Why] Found kernel NULL pointer dereference under the below situation: src — HDMI_Monitor src — HDMI_Monitor e.g.: \ => MSTB — MSTB (unplug) MSTB — MSTB When display 1 HDMI and 2 DP daisy chain monitors, unplugging the dp cable connected to source causes kernel NULL pointer dereference at drm_dp_mst_atomic_check_bw_limit(). When calculating pbn_limit, if branch is null, accessing "&branch->ports" causes the problem. [How] Judge branch is null or not at the beginning. If it is null, return 0.

[PATCH] drm/nouveau: Add correct turing page kinds
by James Jones 06 Jan '20

06 Jan '20

Turing introduced a new simplified page kind scheme, reducing the number of possible page kinds from 256 to 16. It also is the first NVIDIA GPU in which the highest possible page kind value is not reserved as an "invalid" page kind. To address this, the invalid page kind is made an explicit property of the MMU HAL, and a new table of page kinds is added to the tu102 MMU HAL. One hardware change not addressed here is that 0x00 is technically no longer a supported page kind, and pitch surfaces are instead intended to share the block-linear generic page kind 0x06. However, because that will be a rather invasive change to nouveau and 0x00 still works fine in practice on Turing hardware, addressing this new behavior is deferred.

[PATCH v2] drm/nouveau: declare constants as unsigned long long.
by Wambui Karuga 06 Jan '20

06 Jan '20

Explicitly declare constants as unsigned long long to address the following sparse warnings: warning: constant is so big it is long v2: convert to unsigned long long for compatibility with 32-bit architectures.
