| | * drm/dp: Don't attempt AUX transfers when eDP panels are not poweredDouglas Anderson2024-02-281-0/+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.

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.

It will be needed by a follow-up DP tunnel patch, checking the maximum rate the DPRX (sink) supports. Accordingly use the drm_dp_max_dprx_data_rate() name for clarity. This patchset will also switch calling the new DRM function in i915 instead of intel_dp_max_data_rate(). While at it simplify the function documentation/comments, removing parts described already by drm_dp_bw_channel_coding_efficiency(). v2: (Ville) - Remove max_link_rate_kbps. - Simplify the function documentation. v3: - Rebased on latest drm-tip.

In an ideal world this would have been handled by the dma layer, but the TTM page fault handling would have to be rewritten to able to do that. A side-effect of the TTM page fault handling is using a dma allocation per order (via ttm_pool_alloc_page) which makes it impossible to just trivially use dma_mmap_attrs. As a result ttm has to be very careful about trying to make its pgprot for the mapped tt pages match what the dma layer thinks it is. At the ttm layer it's possible to deduce the requirement to have tt pages decrypted by checking whether coherent dma allocations have been requested and the system is running with confidential computing technologies. This approach isn't ideal but keeping TTM matching DMAs expectations for the page properties is in general fragile, unfortunately proper fix would require a rewrite of TTM's page fault handling. Fixes vmwgfx with SEV enabled. v2: Explicitly include cc_platform.h v3: Use CC_ATTR_GUEST_MEM_ENCRYPT instead of CC_ATTR_MEM_ENCRYPT to limit the scope to guests and log when memory decryption is enabled.

These drivers add a list of modes using drm_mode_probed_add() and then set a preferred mode using the drm_set_preferred_mode() helper. It seems more logical to have the helper definition in drm_modes.o instead of drm_edid.o, since the former contains modes helper while the latter has helpers to manage the EDID information. Since both drm_edid.o and drm_modes.o object files are built-in the drm.o object, there are no functional changes. But besides being a more logical place for this helper, it could also allow to eventually make drm_edid.o optional and not included in drm.o if only fixed panels must be supported in a given system.

Thus, it's not truly a "global state", unlike object state structures that do contain the entire state of a given object.

The CRTC commit didn't update the doc of the crtcs field to reflect that, and the doc for the planes and connectors fields mention that they are pointers to an array of structures with per-$OBJECT data. The private_objs field was added later on by commit b430c27a7de3 ("drm: Add driver-private objects to atomic state") reusing the same sentence than the crtcs field, probably due to copy and paste. While these fields are indeed pointers to an array, each item of that array contain a pointer to the object structure affected by the update, and its old and new state. There's no per-object data there, and there's more than just a pointer to the objects. Let's rephrase those fields a bit to better match the current situation.
