2024-12-16drm/i915/display: add intel_display_conversion.c to hide stuff betterJani Nikula
The __to_intel_display() generics require the definition of struct drm_i915_private i.e. inclusion of i915_drv.h. Add intel_display_conversion.c with a __i915_to_display() function to do the conversion without the intel_display_conversion.h having an implicit dependency on i915_drv.h. The long term goal is to remove __to_intel_display() and the intel_display_conversion.[ch] files altoghether, and this is merely a transitional step to make the dependencies on i915_drv.h explicit.

2024-12-16drm/i915: extract intel_uncore_trace.[ch]Jani Nikula
The i915_reg_rw tracing is a small isolated part of i915_trace.h. Its users are orthogonal to the other i915_trace.h users as well, and its implementation does not require all the includes of i915_trace.h. Split i915_reg_rw tracing to separate intel_uncore_trace.[ch]. The main underlying goal is to reduce implicit includes of i915_drv.h from display code.

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.

2024-12-16drm/i915/mst: use intel_dp_compute_config_limits() for DP MSTJani Nikula
There's a lot of duplication between mst_stream_compute_config_limits() and intel_dp_compute_config_limits(). Adjust the latter to suit the needs of the former, and use the same function for both. This reduces duplication and highlights the differences for SST and MST and UHBR. Remove the kernel-doc for intel_dp_compute_config_link_bpp_limits() which now becomes static.

Since commit 13b25489b6f8 ("kbuild: change working directory to external module directory with M="), the Debian package build fails if a relative path is specified with the O= option. $ make O=build bindeb-pkg [ snip ] dpkg-deb: building package 'linux-image-6.13.0-rc1' in '../linux-image-6.13.0-rc1_6.13.0-rc1-6_amd64.deb'.

2024-12-08modpost: Add .irqentry.text to OTHER_SECTIONSThomas Gleixner
The compiler can fully inline the actual handler function of an interrupt entry into the .irqentry.text entry point. If such a function contains an access which has an exception table entry, modpost complains about a section mismatch: WARNING: vmlinux.o(__ex_table+0x447c): Section mismatch in reference ... The relocation at __ex_table+0x447c references section ".irqentry.text" which is not in the list of authorized sections. Add .irqentry.text to OTHER_SECTIONS to cure the issue.
