This patch fixes a bug that was found in the dmabuf flow. Bug description as found on Gaudi2 device: 1. User allocates 4MB of device memory - Note that although the allocation size was 4MB the HMMU allocated a full page of 768MB to back the request. - The user gets a memory handle that points to a single page (768MB) - Mapping the handle, the user gets virtual address to the start of the page. 2. User exports the buffer 3. User registers the exported buffer in the importer. This flow has a callback to the exporter which in turn converts the phys_page_pack to an SG list for the importer. This SG list is of single entry of size 768MB. However, the size that was passed to the importer was only 4MB. The solution for this is to make sure the importer gets exposure only to the exported size. This will be done by fixing the SG created by the exporter to be of the total size of the actual exported memory requested by the user. Signed-off-by:Ohad Sharabi <osharabi@habana.ai> Reviewed-by:

A previous commit deprecated the option to export from handle, leaving the code with no support for devices with virtual memory. This commit modifies the export API in a way that unifies the uAPI to user address for both cases (i.e. with and without MMU support) and add the actual support for devices with virtual memory.

The API to the user which allows exporting DMA buffer from handle is deprecated here. It was never used as it is relevant only for Gaudi2, and the user stack has yet to add support for dmabuf in Gaudi2. Looking forward, a modified API to export DMA buffer for ASICs that supports virtual memory will be added. Until the new API will be ready- exporting DMA buffer will not be supported for ASICs with virtual memory. Signed-off-by:

In certain scenarios, firmware might encounter a fatal event for which a device reset is required. Hence, a proper notification is needed for driver to be aware and initiate a reset sequence. In secured environments the reset will be performed by firmware without an explicit request from the driver. Signed-off-by:

When user context is released and hpriv_release() is called, there is a device idle status check, to understand if user has left the device not idle and then a reset is required. However, if the user process is killed because of device hard reset, the device at this point would always be not idle, because the device engines were already forcefully halted. Modify hpriv_release() to skip the idle check if reset is in progress. Signed-off-by:

The refcount of a CB buffer is initialized when user allocates a CB, and is decreased when he destroys the CB handle. If this refcount is increased also from kernel and user sends more than one destroy requests for the handle, the buffer will be released/freed and later be accessed when the refcount is put from kernel side. To avoid it, prevent user from destroying the handle more than once. Signed-off-by:

User should close the FD when being notified about an error, after which a device reset takes place. However, if the user has pending threads that wait for completions, the device release won't be called and eventually the watchdog timeout will expire, leading to hard reset and killing the user process. To avoid it, abort such waiting threads right after the error notification, and block following waiting operations. Signed-off-by:

The majority of the driver already uses struct iosys_map to encapsulate accesses to I/O remapped vs. system memory. Accesses via the screen base pointer still use __iomem annotations, which can lead to inconsistencies and conflicts with subsequent patches. Convert the screen base to a struct iosys_map as well for consistency and to avoid these issues. Reviewed-by:

The original goal with drm_edid_connector_update() was to have a single call for updating the connector and adding probed modes, in this order, but that turned out to be problematic. Drivers that need to update the connector in the .detect() callback would end up updating the probed modes as well. Turns out the callback may be called so many times that the probed mode list fills up without bounds, and this is amplified by add_alternate_cea_modes() duplicating the CEA modes on every call, actually running out of memory on some machines. Kudos to Imre Deak <imre.deak@intel.com> for explaining this to me. Go back to having separate drm_edid_connector_update() and drm_edid_connector_add_modes() calls. The former may be called from .detect(), .force(), or .get_modes(), but the latter only from .get_modes(). Unlike drm_add_edid_modes(), have drm_edid_connector_add_modes() update the probed modes from the EDID property instead of the passed in EDID. This is mainly to enforce two things: 1) drm_edid_connector_update() must be called before drm_edid_connector_add_modes(). Display info and quirks are needed for parsing the modes, and we don't want to call update_display_info() again to ensure the info is available, like drm_add_edid_modes() does. 2) The same EDID is used for both updating the connector and adding the probed modes. Fortunately, the change is easy, because no driver has actually adopted drm_edid_connector_update(). Not even i915, and that's mainly because of the problem described above.

Separate the parsing of display info and modes from the HDMI VSDB. This is prerequisite work for overall better separation of the two parsing steps. The info parsing is about figuring out whether the sink supports HDMI infoframes. Since they were added in HDMI 1.4, assume the sink supports HDMI infoframes if it has the HDMI_Video_present bit set (introduced in HDMI 1.4). For details, see commit f1781e9b ("drm/edid: Allow HDMI infoframe without VIC or S3D"). The logic is not exactly the same, but since it was somewhat heuristic to begin with, assume this is close enough. v2: - Simplify to only check HDMI_Video_present bit (Ville) - Drop cea_db_raw_size() helper (Ville) Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:
