2025-04-07drm/i915/gvt: fix unterminated-string-initialization warningJani Nikula
Initializing const char opregion_signature[16] = OPREGION_SIGNATURE (which is "IntelGraphicsMem") drops the NUL termination of the string. This is intentional, but the compiler doesn't know this. Switch to initializing header->signature directly from the string litaral, with sizeof destination rather than source. We don't treat the signature as a string other than for initialization; it's really just a blob of binary data. Add a static assert for good measure to cross-check the sizes.

2025-04-01drm/i915/gvt: use hardcoded reference clocksJani Nikula
Usually I'd argue hardcoding values is the wrong thing to do, but in this case, GVT looking deep into the guts of the DPLL manager for the reference clocks is worse. This is done for BDW and BXT only, and there shouldn't be any reason to try to be so dynamic about it. This helps reduce the direct pokes at display guts from non-display code.

Pull drm updates from Dave Airlie: "Outside of drm there are some rust patches from Danilo who maintains that area in here, and some pieces for drm header check tests. The major things in here are a new driver supporting the touchbar displays on M1/M2, the nova-core stub driver which is just the vehicle for adding rust abstractions and start developing a real driver inside of. xe adds support for SVM with a non-driver specific SVM core abstraction that will hopefully be useful for other drivers, along with support for shrinking for TTM devices.

2024-12-16drm/i915/gvt: always pass struct intel_display * to register macrosJani Nikula
The long term goal is to remove the __to_intel_display() generics from display macros, such as register macros. This requires that all such macro usage passes struct intel_display * rather than struct drm_i915_private * to the macros. The short term goal is to hide the struct drm_i915_private access in intel_display_conversions.h into a function. This is problematic with gvt, because it's a separate module, and the conversion function would need to be exported. Make the conversion to always passing struct intel_display * in gvt to unblock both of the above.

2024-07-22drm/i915: Make I2C terminology more inclusiveEaswar Hariharan
I2C v7, SMBus 3.2, and I3C 1.1.1 specifications have replaced "master/slave" with more appropriate terms. Inspired by Wolfram's series to fix drivers/i2c/, fix the terminology for users of I2C_ALGOBIT bitbanging interface, now that the approved verbiage exists in the specification.

2024-06-14drm/i915/gvt: use proper i915_reg_t for calc_index() parametersJani Nikula
In order to be able to use the proper register macros instead of the underscore prefixed ones, pass i915_reg_t for the calc_index() parameters. Side note: DSPSURF is really about planes, not pipes. Fixed stride doesn't work for plane C for CHV (but that's okay for gvt). This doesn't support planes beyond C either. But all that is unrelated to the change at hand.
