Gen2 tiles are 2KiB in size so i915_gem_object_get_tile_row_size() can in fact return <4KiB, which leads to div-by-zero here. Avoid that. Not sure i915_gem_object_get_tile_row_size() is entirely sane anyway since it doesn't account for the different tile layouts on i8xx/i915... I'm not able to hit this before commit 6846895f ("drm/i915: Replace PIN_NONFAULT with calls to PIN_NOEVICT") and it looks like I also need to run recent version of Mesa. With those in place xonotic trips on this quite easily on my 85x. Cc: stable@vger.kernel.org Reviewed-by:

Stolen memory is always allocated as physically contiguous pages, so mark the object flags as such. It looks like the flags were previously just ignored so this had no effect. In the future we might to add the proper plumbing for passing the flags all over the way down from the caller, but for now we don't have a use for that. Signed-off-by:

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:

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. Bspec: 53111 Signed-off-by:

To allow a period in which code will be converted to the new macro, keep IS_GEN_RANGE() around, just redefining it to use the new fields.

Like it was done in commit 01eb15c9 ("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:

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:

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". Signed-off-by:
