Going forwards, the intention is for GuC firmware files to be named for their major version only and HuC firmware files to have no version number in the name at all. This patch adds those entries for all platforms that are officially GuC/HuC enabled. Also, update the expected GuC version numbers to the latest firmware release for those platforms.

All of the functions used for intel_dvo_dev_ops.mode_valid have a return type of enum drm_mode_status, but the mode_valid field in the struct definition has a return type of int. The mismatched return type breaks forward edge kCFI since the underlying function definitions do not match the function hook definition. The return type of the mode_valid field should be changed from int to enum drm_mode_status.

Instead of calling read_clock_frequency() to walk the if/else ladder per platform, move the ladder to intel_gt_init_clock_frequency() and use one function per branch. With the new logic, it's now clear the call to gen9_get_crystal_clock_freq() was just dead code, as gen9 is handled by another function and there is no version 10.

With the new ranges it's easier to see what platform a branch started to be taken. Besides the >= 11 change, the branch taken for GRAPHICS_VER == 10 is also different, but currently there is no such platform in i915.

The earlier update to support reduced versioning of firmware files introduced an issue with the firmware override module parameter. A self test would specify an invalid file name (invalid meaning not in the table) both with and without setting the override flag. The *non-override* case would cause an infinite loop. I.e. a situation that is impossible to hit outside of the selftest because either the file name has come from the table in first place or it came from an override. However, the override case was also broken in that it would bypass some of the later processing. The first fix is to update the scanning loop code so that if an invalid file is passed in, it will exit rather than loop forever. So if the impossible situation did somehow occur in the future, it wouldn't be such a big problem. The second flips the logic on the override early exit to be negative rather than positive. That way if an explicit override has been set, then it won't try to scan for backup options (because there is no point anyway - the user wanted X and if X is not available, that's their problem). It also means that it won't skip code that still needs to be run once a valid firmware file has been selected. v2: Also remove ANSI colour codes that accidentally got left in an error message in the original patch.

In order to keep the context image parser simple, we assume that all commands follow a similar format. A few, especially not MI commands on the render engines, have fixed lengths not encoded in a length field. This caused us to incorrectly skip over 3D state commands, and start interpreting context data as instructions. Eventually, as Daniele discovered, this would lead us to find addition LRI as part of the data and mistakenly add invalid LRI commands to the context probes. Stop parsing after we see the first !MI command, as we know we will have seen all the context registers by that point. (Mostly true for all gen so far, though the render context does have LRI after the first page that we have been ignoring so far. It would be useful to extract those as well so that we have the full list of user accessible registers.) Similarly, emit a warning if we do try to emit an invalid zero-length LRI.

Support for reading the fuses to check what are the Link Copy engines was added in commit ad5f74f3 ("drm/i915/pvc: read fuses for link copy engines"). However they were added unconditionally because the FUSE3 register is present since graphics version 10. However the bitfield with meml3 fuses only exists since graphics version 12. Moreover, Link Copy engines are currently only available in PVC. Tying additional copy engines to the meml3 fuses is not correct for other platforms. Make sure there is a check for `12.60 <= ver < 12.70`. Later platforms may extend this function later if it's needed to fuse off copy engines. Currently it's harmless as the Link Copy engines are still not exported: info->engine_mask only has BCS0 set and the register is only read for platforms that do have it.

The TV encoder has its own special clocking strategy, which means we can't just use intel_crtc_dotclock() to figure out what the resulting dotclock will be given the actual DPLL port_clock. Additionally the DPLL can't always generate exactly the frequency we initially asked for. This results in us computing a bogus dotclock/etc., and it won't match the readout which is handled by the encoder itself properly. Naturally the state checker becomes unhappy with the mismatch. To do this sanely we'll need to move the DPLL computation into encoder->compute_config() so that all the derived state gets correctly computed based on the actual DPLL output frequency. Start doing that just for the TV encoder initally as intel_crtc_dotclock() should be able to handle other encoder types well enough. Though eventually this should be done for all encoder types rather than doing it from intel_crtc_compute_config(). With this we actually do some of the DPLL state computation twice, but we can skip the second actual .find_dpll() search by flagging .clock_set=true after we've done it once. We also still need to avoid clobbering the correct adjusted_mode.crtc_clock set up by encoder->compute_config() when called a second time from intel_crtc_compute_config().

Check for media IP version instead of graphics since this is figuring out the media engines' configuration. Currently the only platform with non-matching graphics/media version is Meteor Lake: update the check in gen11_vdbox_has_sfc() so it considers not only version 12, but also any later version which then includes that platform.
