2021-07-22drm/i915/dg2: Add dbuf programmingMatt Roper2-1/+123
DG2 extends our DDB to four DBuf slices; pipes A+B only have access to the first two slices, whereas pipes C+D only have access to the second two. Confusingly, our bspec decided to switch from 1-based numbering of dbuf slices (S1, S2) to 0-based numbering (S0, S1, S2, S3) in Display13. At the moment we're using the 0-based number scheme for the DBUF_CTL_S() register addressing, but the 1-based number scheme in the actual slice assignment tables. We may want to consider switching the assignment over to 0-based numbering too at some point...

2021-07-22drm/i915: Fork DG1 interrupt handlerPaulo Zanoni5-53/+95
The current interrupt handler is getting increasingly complicated and Xe_HP changes will bring even more complexity. Let's split off a new interrupt handler starting with DG1 (i.e., when the master tile interrupt register was added to the design) and use that as the basis for the new Xe_HP changes. Now that we track the hardware IP's release number as well as the version number, we can also properly define DG1 has version "12.10" and replace the has_master_unit_irq feature flag with an IP version test.

2021-07-22drm/i915: Add XE_HP initial definitionsLucas De Marchi1-0/+24
Our _FEATURES macro went back to GEN7, extending each other, making it difficult to grasp what was really enabled/disabled. Take the opportunity of the GEN -> XE_HP name break and also break with the feature inheritance. For XE_HP this basically goes from GEN12 back to GEN7 coalescing the features making sure the overrides remain, remove all the display-specific features and sort it. Then also remove the definitions that would be overridden by DGFX_FEATURES and those that were 0 (since that is the default). Exception here is has_master_unit_irq: although it is a feature that started with DG1 and is true for all DGFX platforms, it's also true for XE_HP in general.

2021-07-22drm/i915: Add release id versionLucas De Marchi3-2/+18
Besides the arch version returned by GRAPHICS_VER(), new platforms contain a "release id" to make clear the difference from one platform to another. The release id number is not formally defined by hardware until future platforms that will expose it via a new GMD_ID register. For the platforms we support before that register becomes available we will set the values in software and we can set them as we please. So the plan is to set them so we can group different features under a single GRAPHICS_VER_FULL() check. After GMD_ID is used, the usefulness of a "full version check" will be greatly reduced and will be mostly used for deciding workarounds and a few code paths. So it makes sense to keep it as a separate field from graphics_ver. Also, as a platform with `release == n` may be closer feature-wise to `n - 2` than to `n - 1`, use the word "release" rather than the more common "minor" for this This is a mix of 2 independent changes: one by me and the other by Matt Roper. v2: - Reword commit message to make it clearer why we don't call it "minor" (Matt Roper and Tvrtko) - Rename variables s/*_ver_release/*_rel/ and print them in a single line formatted as {ver}.{rel:2} (Jani and Matt Roper) Cc: Matt Roper <matthew.d.roper@intel.com> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Signed-off-by: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210707235921.2416911-2-lucas.demarchi@intel.com (cherry picked from commit ca6374e267e2735fe382fe95de2a8a9c30c6bdb3) Signed-off-by: Matt Roper <matthew.d.roper@intel.com>

2021-07-21drm/i915: Make display workaround upper bounds exclusiveMatt Roper7-21/+21
Workarounds are documented in the bspec with an exclusive upper bound (i.e., a "fixed" stepping that no longer needs the workaround). This makes our driver's use of an inclusive upper bound for stepping ranges confusing; the differing notation between code and bspec makes it very easy for mistakes to creep in. Let's switch the upper bound of our IS_{GT,DISP}_STEP macros over to use an exclusive upper bound like the bspec does. This also has the benefit of helping make sure workarounds are properly handled for new minor steppings that show up (e.g., an A1 between the A0 and B0 we already knew about) --- if the new intermediate stepping pulls in hardware fixes early, there will be an update to the workaround definition which lets us know we need to change our code. If the new stepping does not pull a hardware fix earlier, then the new stepping will already be captured properly by the "[begin, fix)" range in the code. We'll probably need to be extra vigilant in code review of new workarounds for the near future to make sure developers notice the new semantics of workaround bounds. But we just migrated a bunch of our platforms from the IS_REVID bounds over to IS_{GT,DISP}_STEP, so people are already adjusting to the new macros and now is a good time to make this change too.

Switch ICL to use a revid->stepping table as we're trying to do on all platforms going forward.

Note that the current bspec table is missing information about how to map PCI revision ID to GT/display steppings; it only provides an SoC stepping. The mapping to GT/display steppings (which aren't always the same as the SoC stepping) used to be in the bspec, but was apparently dropped during an update in Nov 2019; I've made my changes here based on an older bspec snapshot that still had the necessary information. We've requested that the missing information be restored. I'm only including the production revids in the table here since we're past the point at which we usually stop trying to support pre-production hardware. An appropriate check is added to intel_detect_preproduction_hw() to print an error and taint the kernel just in case someone still tries to load the driver on old pre-production hardware. v2: - Drop pre-production steppings and add error/taint at startup when loading on pre-production hardware.

2021-07-14drm/i915/skl: Use revid->stepping tablesMatt Roper4-16/+31
Switch SKL to use a revid->stepping table as we're trying to do on all platforms going forward. Also drop the preproduction revisions and add the newer steppings we hadn't already handled. Note that SKL has a case where a newer revision ID corresponds to an older GT/disp stepping (0x9 -> STEP_J0, 0xA -> STEP_I1). Also, the lack of a revision ID 0x8 in the table is intentional and not an oversight. We'll re-write the KBL-specific comment to make it clear that these kind of quirks are expected. v2: - Since GT and display steppings are always identical on SKL use a macro to set both values at once in a more readable manner. (Anusha) - Drop preproduction steppings.

2021-07-14drm/i915: Make pre-production detection use direct revid comparisonMatt Roper1-4/+4
Although we're converting our workarounds to use a revid->stepping lookup table, the function that detects pre-production hardware should continue to compare against PCI revision ID values directly. These are listed in the bspec as integers, so it's easier to confirm their correctness if we just use an integer literal rather than a symbolic name anyway.

2021-07-11drm/i915: Invoke another _DSM to enable MUX on HP Workstation laptopsKai-Heng Feng3-0/+25
On HP Fury G7 Workstations, graphics output is re-routed from Intel GFX to discrete GFX after S3. This is not desirable, because userspace will treat connected display as a new one, losing display settings. The expected behavior is to let discrete GFX drives all external displays. The platform in question uses ACPI method \_SB.PCI0.HGME to enable MUX. The method is inside the another _DSM, so add the _DSM and call it accordingly. I also tested some MUX-less and iGPU only laptops with that _DSM, no regression was found. v4: - Rebase. - Change the DSM name to avoid confusion. - Move the function call to intel_opregion. v3: - Remove BXT from names. - Change the parameter type. - Fold the function into intel_modeset_init_hw(). v2: - Forward declare struct pci_dev.
