2024-03-18drm: Fix drm_fixp2int_round() making it add 0.5Arthur Grillo1-2/+1
As well noted by Pekka[1], the rounding of drm_fixp2int_round is wrong. To round a number, you need to add 0.5 to the number and floor that, drm_fixp2int_round() is adding 0.0000076. Make it add 0.5.

2024-03-14drm/edid: Add a function to match EDID with identityHsin-Yi Wang1-0/+9
Create a type drm_edid_ident as the identity of an EDID. Currently it contains panel id and monitor name. Create a function that can match a given EDID and an identity: 1. Reject if the panel id doesn't match. 2. If name is not null in identity, try to match it in the detailed timing blocks. Note that some panel vendors put the monitor name after EDID_DETAIL_MONITOR_STRING.

2024-03-14drm_edid: Add a function to get EDID base blockHsin-Yi Wang1-1/+2
It's found that some panels have variants that they share the same panel id although their EDID and names are different. Besides panel id, now we need more information from the EDID base block to distinguish these panel variants. Add drm_edid_read_base_block() to return the EDID base block, which is wrapped in struct drm_edid. Caller can further use it to get panel id or check if the block contains certain strings, such as panel name. Merge drm_edid_get_panel_id() and edid_extract_panel_id() into one function.

2024-03-13drm/probe-helper: warn about negative .get_modes()Jani Nikula1-1/+2
The .get_modes() callback is supposed to return the number of modes, never a negative error code. If a negative value is returned, it'll just be interpreted as a negative count, and added to previous calculations. Document the rules, but handle the negative values gracefully with an error message.

2024-03-11drm/fbdev-generic: Fix locking with drm_client_buffer_vmap_local()Thomas Zimmermann2-0/+13
Temporarily lock the fbdev buffer object during updates to prevent memory managers from evicting/moving the buffer. Moving a buffer object while update its content results in undefined behaviour. Fbdev-generic updates its buffer object from a shadow buffer. Gem-shmem and gem-dma helpers do not move buffer objects, so they are safe to be used with fbdev-generic. Gem-vram and qxl are based on TTM, but pin buffer objects are part of the vmap operation. So both are also safe to be used with fbdev-generic. Amdgpu and nouveau do not pin or lock the buffer object during an update. Their TTM-based memory management could move the buffer object while the update is ongoing. The new vmap_local and vunmap_local helpers hold the buffer object's reservation lock during the buffer update. This prevents moving the buffer object on all memory managers.

2024-03-11drm/gem: Acquire reservation lock in drm_gem_{pin/unpin}()Thomas Zimmermann1-10/+1
Acquire the buffer object's reservation lock in drm_gem_pin() and remove locking the drivers' GEM callbacks where necessary. Same for unpin(). DRM drivers and memory managers modified by this patch will now have correct dma-buf locking semantics: the caller is responsible for holding the reservation lock when calling the pin or unpin callback. DRM drivers and memory managers that are not modified will now be protected against concurent invocation of their pin and unpin callbacks. PRIME does not implement struct dma_buf_ops.pin, which requires the caller to hold the reservation lock. It does implement struct dma_buf_ops.attach, which requires to callee to acquire the reservation lock. The PRIME code uses drm_gem_pin(), so locks are now taken as specified. Same for unpin and detach. The patch harmonizes GEM pin and unpin to have non-interruptible reservation locking across all drivers, as is already the case for vmap and vunmap. This affects gem-shmem, gem-vram, loongson, qxl and radeon.

2024-02-28drm/dp: Don't attempt AUX transfers when eDP panels are not poweredDouglas Anderson1-0/+6
If an eDP panel is not powered on then any attempts to talk to it over the DP AUX channel will timeout. Unfortunately these attempts may be quite slow. Userspace can initiate these attempts either via a /dev/drm_dp_auxN device or via the created i2c device. Making the DP AUX drivers timeout faster is a difficult proposition. In theory we could just poll the panel's HPD line in the AUX transfer function and immediately return an error there. However, this is easier said than done. For one thing, there's no hard requirement to hook the HPD line up for eDP panels and it's OK to just delay a fixed amount. For another thing, the HPD line may not be fast to probe. On parade-ps8640 we need to wait for the bridge chip's firmware to boot before we can get the HPD line and this is a slow process. The fact that the transfers are taking so long to timeout is causing real problems. The open source fwupd daemon sometimes scans DP busses looking for devices whose firmware need updating. If it happens to scan while a panel is turned off this scan can take a long time. The fwupd daemon could try to be smarter and only scan when eDP panels are turned on, but we can also improve the behavior in the kernel. Let's let eDP panels drivers specify that a panel is turned off and then modify the common AUX transfer code not to attempt a transfer in this case.

2024-02-27drm/dp: Add support for DP tunnelingImre Deak2-0/+308
Add support for Display Port tunneling. For now this includes the support for Bandwidth Allocation Mode (BWA), leaving adding Panel Replay support for later. BWA allows using displays that share the same (Thunderbolt) link with their maximum resolution. Atm, this may not be possible due to the coarse granularity of partitioning the link BW among the displays on the link: the BW allocation policy is in a SW/FW/HW component on the link (on Thunderbolt it's the SW or FW Connection Manager), independent of the driver. This policy will set the DPRX maximum rate and lane count DPCD registers the GFX driver will see (0x00000, 0x00001, 0x02200, 0x02201) based on the available link BW. The granularity of the current BW allocation policy is coarse, based on the required link rate in the 1.62Gbs..8.1Gbps range and it may prevent using higher resolutions all together: the display connected first will get a share of the link BW which corresponds to its full DPRX capability (regardless of the actual mode it uses). A subsequent display connected will only get the remaining BW, which could be well below its full capability. BWA solves the above coarse granularity (reducing it to a 250Mbs..1Gps range) and first-come/first-served issues by letting the driver request the BW for each display on a link which reflects the actual modes the displays use. This patch adds the DRM core helper functions, while a follow-up change in the patchset takes them into use in the i915 driver. v2: - Fix prepare_to_wait vs. wake-up cond check order in allocate_tunnel_bw(). (Ville) - Move tunnel==NULL checks from callers in drivers to here. (Ville) - Avoid var inits in declaration blocks that can fail or have side-effects. (Ville) - Use u8 for driver and group IDs. (Ville) - Simplify API removing drm_dp_tunnel_get/put_untracked(). (Ville) - Reuse str_yes_no() instead of a local yes_no_chr(). (Ville) - s/drm_dp_tunnel_atomic_clear_state()/free_tunnel_state() and unexport the function. (Ville) - s/clear_tunnel_group_state()/free_group_state() and move kfree() to this function. (Ville) - Add separate group_free_bw() helper and describe what the tunnel estimated BW includes. (Ville) - Improve help text for CONFIG_DRM_DISPLAY_DP_TUNNEL. (Ville) - Add code comment explaining the purpose of DPCD reg read helpers. (Ville) - Add code comment describing the tunnel group name prefix format. (Ville) - Report the allocated BW as undetermined until the first allocation request. - Skip allocation requests matching the previous request. - Clear any stale BW request status flags before a new request. - Add missing error return check of drm_dp_tunnel_atomic_get_group_state() in drm_dp_tunnel_atomic_set_stream_bw(). - Add drm_dp_tunnel_get_allocated_bw(). - s/drm_dp_tunnel_atomic_get_tunnel_bw/drm_dp_tunnel_atomic_get_required_bw - Fix return value description in function doc of drm_dp_tunnel_detect(). - Add function documentation to all exported functions. v3: - Improve grouping of fields in drm_dp_tunnel_group struct.
