2021-04-22drm/i915: Create stolen memory region from local memoryCQ Tang
Add "REGION_STOLEN" device info to dg1, create stolen memory region from upper portion of local device memory, starting from DSMBASE. v2: - s/drm_info/drm_dbg; userspace likely doesn't care about stolen. - mem->type is only setup after the region probe, so setting the name as stolen-local or stolen-system based on this value won't work. Split system vs local stolen setup to fix this. - kill all the region->devmem/is_devmem stuff. We already differentiate the different types of stolen so such things shouldn't be needed anymore. v3: - split stolen lmem vs smem ops(Tvrtko) - add shortcut for stolen region in i915(Tvrtko) - sanity check dsm base vs bar size(Xinyun) v4(Tvrtko): - more cleanup - add some TODOs Signed-off-by: CQ Tang <cq.tang@intel.com> Signed-off-by: Matthew Auld <matthew.auld@intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Cc: Xinyun Liu <xinyun.liu@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210421104658.304142-1-matthew.auld@intel.com
2021-04-21drm/i915/lmem: Fail driver init if LMEM training failedMatt Roper
Boot firmware performs memory training and health assessment during startup. If the memory training fails, the firmware will consider the GPU unusable and will instruct the punit to keep the GT powered down. If this happens, our driver will be unable to communicate with the GT (all GT registers will read back as 0, forcewake requests will timeout, etc.) so we should abort driver initialization if this happens. We can confirm that LMEM was initialized successfully via sgunit register GU_CNTL.

2021-04-14drm/i915: add macros for graphics and media versionsLucas De Marchi
Like it was done in commit 01eb15c9165e ("drm/i915: Add DISPLAY_VER() and related macros") add the correspondent macros for graphics and media. Going forward we will prefer checking the versions for the specific IPs (graphics, media and display) rather than grouping everything under a "gen" version. For consistency and to make the maintenance easier, it'd be preferred not to mix the *GEN* macros with the new ones. For older platforms we can simply consider that the previous "gen" number will extend to all 3 IPs. Then we can start replacing its use in the driver. Right now this replacement is not done and only the infrastructure is put in place. We also leave gen and gen_mask inside struct intel_device_info while it's still being used throughout the code. v2: Repurpose IS_{GRAPHICS,MEDIA}_VER() macros to work with a range Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by: José Roberto de Souza <jose.souza@intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> [Jani: Minor code comment change while applying.] Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210413051002.92589-5-lucas.demarchi@intel.com
2021-04-14drm/i915/display: rename display version macrosLucas De Marchi
While converting the rest of the driver to use GRAPHICS_VER() and MEDIA_VER(), following what was done for display, some discussions went back on what we did for display: 1) Why is the == comparison special that deserves a separate macro instead of just getting the version and comparing directly like is done for >, >=, <=? 2) IS_DISPLAY_RANGE() is weird in that it omits the "_VER" for brevity. If we remove the current users of IS_DISPLAY_VER(), we could actually repurpose it for a range check With (1) there could be an advantage if we used gen_mask since multiple conditionals be combined by the compiler in a single and instruction and check the result. However a) INTEL_GEN() doesn't use the mask since it would make the code bigger everywhere else and b) in the cases it made sense, it also made sense to convert to the _RANGE() variant. So here we repurpose IS_DISPLAY_VER() to work with a [ from, to ] range like was the IS_DISPLAY_RANGE() and convert the current IS_DISPLAY_VER() users to use == and != operators. Aside from the definition changes, this was done by the following semantic patch: @@ expression dev_priv, E1; @@ - !IS_DISPLAY_VER(dev_priv, E1) + DISPLAY_VER(dev_priv) != E1 @@ expression dev_priv, E1; @@ - IS_DISPLAY_VER(dev_priv, E1) + DISPLAY_VER(dev_priv) == E1 @@ expression dev_priv, from, until; @@ - IS_DISPLAY_RANGE(dev_priv, from, until) + IS_DISPLAY_VER(dev_priv, from, until) Cc: Jani Nikula <jani.nikula@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> [Jani: Minor conflict resolve while applying.] Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20210413051002.92589-4-lucas.demarchi@intel.com
2021-04-14drm/i915: rename display.version to display.verLucas De Marchi
The macro we use to check is called DISPLAY_VER(). While using this macro and the new ones being added in following changes I made the mistake multiple times when mixing both "ver" and "version". Although it's usually better to prefer the complete name, the shorhand DISPLAY_VER() / GRAPHICS_VER / MEDIA_VER are clear and cause less visual polution. Another issue is when copying the variable to other places. "display.version" would be copied to a "display_version" variable which is long and would make people abbreviate as "version", or "display_ver". In the first case it's not always clear what version refers to, and in the second case it just hints it should be the name in the first place. So, in the same way use used "gen" rather than "generation", use "ver" instead of "version".

2021-03-29drm/i915: Add support for FBs requiring a POT stride alignmentImre Deak
An upcoming platform has a restriction that the FB stride must be power-of-two aligned. To support framebuffer layouts that are not in this layout add a logic that pads the tile rows to the POT aligned size. The HW won't read the padding PTEs, so these don't have to point to an allocated address, or even have their valid flag set. So use a NULL PTE instead for instance the scratch page, which is simple and keeps the SG table compact. v2: - Simplify plane_view_dst_stride().

2021-03-29drm/i915: Simplify copying the FB view state to the plane stateImre Deak
Instead of copying separately the GTT remapped and color plane view info from the FB to the plane state, do this by copying the whole intel_fb_view struct. For this we make sure the FB view state is fully inited (that is also including the view type) already during FB creation, so this init is not required during atomic check time. This also means the we don't need to reset the unused color plane info during atomic check, as these are already reset during FB creation. I noticed that initial FBs will only work atm if they are page aligned (which BIOS most probably always ensures), but add a comment to sanitize this part once. Also we won't disable the plane if get_initial_plane_config() failed for some reason (for instance due to unsupported rotation), add a TODO: comment for this too.

2021-03-29drm/i915: Unify the FB and plane state view information into one structImre Deak
To allow the simplification of FB/plane view computation in the follow-up patches, unify the corresponding state in the intel_framebuffer and intel_plane_state structs into a new intel_fb_view struct. This adds some overhead to intel_framebuffer as the rotated view will have now space for 4 color planes instead of the required 2 and it'll also contain the unused offset for each color_plane info. Imo this is an acceptable trade-off to get a simplified way of the remap computation. Use the new intel_fb_view struct for the FB normal view as well, so (in the follow-up patches) we can remove the special casing for normal view calculation wrt. the calculation of remapped/rotated views. This also adds an overhead to the intel_framebuffer struct, as the gtt remap info and per-color plane offset/pitch is not required for the normal view, but imo this is an acceptable trade-off as above. The per-color plane pitch filed will be used by a follow-up patch, so we can retrieve the pitch for each view in the same way. No functional changes in this patch. v2: - Make the patch have _no functional change_.
