Merge tag 'drm-habanalabs-next-2023-01-26' of https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux into drm-next This tag contains habanalabs driver and accel changes for v6.3: - Moved the driver to the accel subsystem. Currently only the files were moved (including the uapi file which was also renamed). This doesn't include registering to the accel subsystem. This will probably be only in the next kernel version. - In case of decoder error (axi error) in Gaudi2, we can now find the exact IP that initiated the erroneous transaction and print the details for better debug. - Add more trace events. We now can trace mmio transactions and communication with the preboot firmware. - Add to Gaudi2 support for abrupt reset that is done by the firmware. This was support so far only for Gaudi1. - Add uAPI to flush memory transactions (to the device memory). This is needed by the communications library in case of doing p2p with a host NIC which access our HBM directly through the PCI BAR. - Add uAPI to pass-through a request from user-space to firmware and get the result back to user-space. This will allow the driver code to avoid the need to add new packet (in the communication channel with the firmware) for every new request type. - Remove the option to export dma-buf by memory allocation handle in our uAPI. This was planned for Gaudi2 but was never used. Instead, we will do export by memory address (same as Gaudi1). In addition, we added the option to specify an offset to the address. This is needed in Gaudi2 because there the user allocates the entire HBM in one allocation, but would like to export only small part of it. - Multiple bug fixes, refactors and small optimizations.

Use the RUNTIME_PM_OPS() and pm_ptr() macros to handle the .runtime_suspend/.runtime_resume callbacks. These macros allow the suspend and resume functions to be automatically dropped by the compiler when CONFIG_PM is disabled, without having to use #ifdef guards. This has the advantage of always compiling these functions in, independently of any Kconfig option. Thanks to that, bugs and other regressions are subsequently easier to catch. Signed-off-by:

Currently all fences have a 30 second timeout to ensure they are cleaned up if the fence never completes otherwise. However, this one size fits all solution doesn't actually fit in every case, such as syncpoint waiting where we want to be able to have timeouts longer than 30 seconds. As such, we want to be able to give control over fence cancellation to the caller (and maybe eventually get rid of the internal timeout altogether). Here we add this cancellation mechanism by essentially adding a function for entering the timeout path by function call, and changing the syncpoint wait function to use it. Signed-off-by:

Move from the old, complex intr handling code to a new implementation based on dma_fences. While there is a fair bit of churn to get there, the new implementation is much simpler and likely faster as well due to allowing signaling directly from interrupt context. Signed-off-by:

In anticipation of removal of the intr API, implement job tracking using DMA fences instead. The main two things about this are making cdma_update schedule the work since fence completion can now be called from interrupt context, and some complication in ensuring the callback is not running when we free the fence.

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. Signed-off-by:

It's a bit confusing to have two cached EDIDs in struct intel_connector with slightly different purposes. Make the distinction a bit clearer by moving the EDID cached for eDP and LVDS panels at connector init time to struct intel_panel, and name it fixed_edid. That's what it is, a fixed EDID for the panels. Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

Jani Nikula authored
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. (The big behavioural change conflating EDID reading with parsing and property update was done in commit 5186421c ("drm: Introduce epoch counter to drm_connector")) v6: Rebase on drm_edid_connector_add_modes() v5: Fix potential uninitialized var use (kernel test robot <lkp@intel.com>) v4: Call drm_edid_connector_update() after reading HDMI/DP EDID v3: Don't leak vga switcheroo EDID in LVDS init (Ville) v2: Don't leak opregion fallback EDID (Ville) Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

When a decode error happens, we often don't know the exact root cause (the erroneous address that was accessed) and the exact engine that created the erroneous transaction. To find out, we need to go over all the relevant register blocks in the ASIC. Once we find the relevant engine, we print its details and the offending address. This helps tremendously when debugging an error that was created by running a user workload. Signed-off-by:

Handling edma razwi is different than all other engines since edma uses sft routers. For hbw transactions sft router contain separate interface for each edma and for lbw there is common interface for both edma engines of the same dcore. To handle the razwi correctly we need to: 1. Simplify the calculation of the sft router address. 2. Add razwi handling for edma qm errors, since edma qman doesn't reports axi error response. Signed-off-by:

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. Signed-off-by:
