| | * mdss: msm: hdmi: fix CEC broadcast loopback issueVenkata Prahlad Valluru2020-03-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A new logical address is searched and allocated when HDMI hotplug interrupt happens. But there might be pending broadcast messages which are being handled with the old logical address, then the messages are received back again causing loopback issue. To fix this, abort CEC message sending if the message is broadcasting and the sender's logical address is different than the current logical address.

| | * mdss: msm: hdmi: use circular buffer for CEC rxVenkata Prahlad Valluru2020-03-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's only one CEC message buffer which could be overwritten if the next interrupt happens before the workthread reads the buffer. To resolve this, defined 4 circular buffers (practially 3 due to linux circular buffer limitation) to rotate the buffer. Since CEC is slow bus, 3 buffers should be enough to avoid potential message overwriting.

| | * mdss: msm: hdmi: add CEC clear_logical_addr sysnodeVenkata Prahlad Valluru2020-03-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the logical address is cleared, CEC hal sets the logical address to 15 but kernel cannot determine whether the logical address is cleared or set to 15. To clearly detect that the logical address is cleared, a new sysnode "clear_logical_addr" is added. If clear_logical_addr is set to 1, then kernel ignores received CEC messages until it's reset to 0.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reset previous EDID's deep_color value before parsing new EDID. HDMI driver is already checking if sink supports deep color or not using hdmi_tx_sink_dc_support function. Remove dc_support check which is redundant.

| * | msm: mdss: hdmi: handle HPD disconnect event during suspendNarender Ankam2020-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On device suspend, HDMI fb node is powered down. If HDMI cable is now disconnected in suspend state, even though DISCONNECT event is notified to display HAL to close HDMI fb node, fb driver early returns since this fb node is already powered off. As a result, HPD polarity is never configured to detect HPD high (connect) and no subsequent HPD connections will be ever detected. So on receiving HPD Disconnect event, configure HPD polarity to detect HPD High if HDMI panel is already powered off. Also make sure no HPD event is notified if same event is already notified and waiting for completion.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For repeaters having zero device count, the HDCP CTS expects the device under test to either read V' and perform full authentication or not read V' and re-authenticate. Current HDCP driver reads V' and also re-authenticates causing a failure of zero device count repeater test cases. Fix this issue by implementing the correct sequence in case of zero downstream devices.

* fbdev: msm: Avoid UAF in mdss_dsi_cmd_writeNirmal Abraham2019-10-15
| | | | | | | | | | | | In mdss_dsi_cmd_write, a failure in copying the cmds to 'string_buf' can cause an early return. In this case, the 'pcmds->string_buf' won't be pointing to a valid buffer. This can lead to use-after-free and memory leak. To avoid this, assign the newly allocated buffer to 'pcmds->string_buf' after returning from krealloc call.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | HDMI 2.0 compliance E-DDC test requires the DDC signal timings to meet a minimum threshold to pass the compliance test. Current DDC settings were not matching the requirement. Adjust the DDC settings to meet the threshold and also make sure to leave the remaining bits of DDC speed register untouched.

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | In hdmi-as-primary usecase with resolution change, the vsync_handler can get called from overlay_on function before the vsync handler is registered via ctl_start. Add a check to avoid the null ptr access while accessing the vsync handler function ptr in this case.
