2023-01-26gpu: host1x: Implement syncpoint wait using DMA fencesMikko Perttunen
In anticipation of removal of the intr API, move host1x_syncpt_wait to use DMA fences instead. As of this patch, this means that waits have a 30 second maximum timeout because of the implicit timeout we have with fences, but that will be lifted in a follow-up patch.

2023-01-26Partially revert "perf/arm-cmn: Optimise DTC counter accesses"Robin Murphy
It turns out the optimisation implemented by commit 4f2c3872dde5 is totally broken, since all the places that consume hw->dtcs_used for events other than cycle count are still not expecting it to be sparsely populated, and fail to read all the relevant DTC counters correctly if so. If implemented correctly, the optimisation potentially saves up to 3 register reads per event update, which is reasonably significant for events targeting a single node, but still not worth a massive amount of additional code complexity overall. Getting it right within the current design looks a fair bit more involved than it was ever intended to be, so let's just make a functional revert which restores the old behaviour while still backporting easily.

2023-01-26drm/i915/edid: convert DP, HDMI and LVDS to drm_edidJani Nikula
Convert all the connectors that use cached connector edid and detect_edid to drm_edid. Since drm_get_edid() calls drm_connector_update_edid_property() while drm_edid_read*() do not, we need to call drm_edid_connector_update() separately, in part due to the EDID caching behaviour in HDMI and DP. Especially DP depends on the details parsed from EDID.

2023-01-26habanalabs: block soft-reset on an unusable deviceKoby Elbaz
A device with status malfunction indicates that it can't be used. In such a case we do not support certain reset types, e.g., all kinds of soft-resets (compute reset, inference soft-reset), and reset upon device release. A hard-reset is the only way that an unusable device can change its status. All other reset procedures can't put the device in a reset procedure, which might ultimately cause the device to change its status, unintentionally, to become operational again. Such a scenario has recently occurred, when a user requested a hard-reset while another heavy user workload was ongoing (reset request is queued). Since the workload couldn't finish within reset's timeout limits, the reset has failed and set a device status malfunction. Eventually, when the user released the FD, an unsuccessful soft-reset occurred, hence followed by an additional hard-reset that changed the ASICs status back to be operational.

2023-01-26habanalabs/gaudi: allow device acquire while in debug modeOfir Bitton
During device acquire, the driver is using a QMAN for clearing some registers. In order to avoid internal races, the driver verifies the device is idle before submitting the register clear job. This check introduces an issue, as debug mode will cause the device to be non-idle which will lead to device acquire failure. In order to overcome this issue we can entirely remove the idle check as the driver is using the QMAN only when there is no active context.
