Looks like our VBIOS/GOP generally fail to turn the DP dual mode adater TMDS output buffers back on after a reboot. This leads to a black screen after reboot if we turned the TMDS output buffers off prior to reboot. And if i915 decides to do a fastboot the black screen will persist even after i915 takes over. Apparently this has been a problem ever since commit b2ccb822 ("drm/i915: Enable/disable TMDS output buffers in DP++ adaptor as needed") if one rebooted while the display was turned off. And things became worse with commit fe0f1e3b ("drm/i915: Shut down displays gracefully on reboot") since now we always turn the display off before a reboot. This was reported on a RKL, but I confirmed the same behaviour on my SNB as well. So looks pretty universal. Let's fix this by explicitly turning the TMDS output buffers back on in the encoder->shutdown() hook. Note that this gets called after irqs have been disabled, so the i2c communication with the DP dual mode adapter has to be performed via polling (which the gmbus code is perfectly happy to do for us). We also need a bit of care in handling DDI encoders which may or may not be set up for HDMI output. Specifically ddc_pin will not be populated for a DP only DDI encoder, in which case we don't want to call intel_gmbus_get_adapter(). We can handle that by simply doing the dual mode adapter type check before calling intel_gmbus_get_adapter().

My previous patch correctly addressed the possible link failure, but as Jani points out, the dependency is now stricter than it needs to be. Change it again, to allow DRM_FBDEV_EMULATION to be used when DRM_KMS_HELPER and FB are both loadable modules and DRM is linked into the kernel. As a side-effect, the option is now only visible when at least one DRM driver makes use of DRM_KMS_HELPER. This is better, because the option has no effect otherwise.

The huge page functionality in TTM does not work safely because PUD and PMD entries do not have a special bit. get_user_pages_fast() considers any page that passed pmd_huge() as usable: if (unlikely(pmd_trans_huge(pmd) || pmd_huge(pmd) || pmd_devmap(pmd))) { And vmf_insert_pfn_pmd_prot() unconditionally sets entry = pmd_mkhuge(pfn_t_pmd(pfn, prot)); eg on x86 the page will be _PAGE_PRESENT | PAGE_PSE. As such gup_huge_pmd() will try to deref a struct page: head = try_grab_compound_head(pmd_page(orig), refs, flags); and thus crash. Thomas further notices that the drivers are not expecting the struct page to be used by anything - in particular the refcount incr above will cause them to malfunction. Thus everything about this is not able to fully work correctly considering GUP_fast. Delete it entirely. It can return someday along with a proper PMD/PUD_SPECIAL bit in the page table itself to gate GUP_fast.

[WHY] If timing and bpp of displays on mst hub are not changed, pbn, slot_num for displays should not be changed. Linux user mode may initiate atomic_check with different display configuration after set mode finished. This will call to amdgpu_dm to re-compute payload, slot_num of displays and saved to dm_connect_state. stream->timing.flags.dsc, pbn, slot_num are updated to values which may be different from that were used for set mode. when dsc hub with 3 4k@60hz dp connected, 3 dsc engines are enabled. timing.flags.dsc = 1. timing.flags.dsc are changed to 0 due to atomic check. when dsc hub is unplugged, amdgpu driver check timing.flags.dsc for last mode set and find out flags.dsc = 0, then does not disable dsc. [HOW] check status of displays on dsc mst hubs. re-compute pbn, slot_num, timing.flags.dsc only if there is mode, connect or enable/disable change. Acked-by:

commit 652de07a ("drm/amd/display: Fully switch to dmub for all dcn21 asics") switched over to using dmub on Renoir to fix Gitlab 1735, but this implied a new dependency on newer firmware which might not be met on older kernel versions. Since sw_init runs before hw_init, there is an opportunity to determine whether or not the firmware version is new to adjust the behavior.
