2022-11-04drm/i915/guc: Remove excessive line feeds in state dumpsJohn Harrison
Some of the GuC state dump messages were adding extra line feeds. When printing via a DRM printer to dmesg, for example, that messes up the log formatting as it loses any prefixing from the printer. Given that the extra line feeds are just in the middle of random bits of GuC state, there isn't any real need for them. So just remove them completely.

2022-11-04drm/i915/userptr: restore probe_range behaviourMatthew Auld
The conversion looks harmless, however the addr value is updated inside the loop with the previous vm_end, which then incorrectly leads to for_each_vma_range() iterating over stuff outside the range we care about. Fix this by storing the end value separately. Also fix the case where the range doesn't intersect with any vma, or if the vma itself doesn't extend the entire range, which must mean we have hole at the end. Both should result in an error, as per the previous behaviour. v2: Fix the cases where the range is empty, or if there's a hole at the end of the range Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/7247 Testcase: igt@gem_userptr_blits@probe Fixes: f683b9d61319 ("i915: use the VMA iterator") Reported-by: kernel test robot <oliver.sang@intel.com> Signed-off-by: Matthew Auld <matthew.auld@intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Cc: Matthew Wilcox (Oracle) <willy@infradead.org> Cc: Liam R.

2022-11-04drm/ingenic: Fix missing platform_driver_unregister() call in ingenic_drm_init()Yuan Can
A problem about modprobe ingenic-drm failed is triggered with the following log given: [ 303.561088] Error: Driver 'ingenic-ipu' is already registered, aborting... modprobe: ERROR: could not insert 'ingenic_drm': Device or resource busy The reason is that ingenic_drm_init() returns platform_driver_register() directly without checking its return value, if platform_driver_register() failed, it returns without unregistering ingenic_ipu_driver_ptr, resulting the ingenic-drm can never be installed later. A simple call graph is shown as below: ingenic_drm_init() platform_driver_register() # ingenic_ipu_driver_ptr are registered platform_driver_register() driver_register() bus_add_driver() priv = kzalloc(...) # OOM happened # return without unregister ingenic_ipu_driver_ptr Fixing this problem by checking the return value of platform_driver_register() and do platform_unregister_drivers() if error happened.

2022-11-03drm/i915: Share {csc,gamma}_enable calculation for ilk/snb vs. ivb+Ville Syrjälä
ilk/snb vs. ivb+ hardware is mostly identical except for the addition of the split gamma mode on ivb. Thus we can share the csc_enable and gamma_enable calculation for both variants. Pull that stuff into a few helpers. Note that this also fills in the missing ctm/degamma stuff into ilk_color_check() pretty much, so for good measure let's also add a few extra checks relating to that, although we still don't expose ctm/degamma to userspace. But now it'll be trivial to do so if we wish.

2022-11-03drm/i915/selftests: Reduce oversaturation of request smoketestingChris Wilson
The goal in launching the request smoketest is to have sufficient tasks running across the system such that we are likely to detect concurrency issues. We aim to have 2 tasks using the same engine, gt, device (each level of locking around submission and signaling) running at the same time. While tasks may not be running all the time as they synchronise with the gpu, they will be running most of the time, in which case having many more tasks than cores available is wasteful (and dramatically increases the workload causing excess runtime). Aim to limit the number of tasks such that there is at least 2 running per engine, spreading surplus cores around the engines (rather than running a task per core per engine.)

2022-11-03drm/meson: Fix return type of meson_encoder_cvbs_mode_valid()Nathan Chancellor
With clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG), indirect call targets are validated against the expected function pointer prototype to make sure the call target is valid to help mitigate ROP attacks. If they are not identical, there is a failure at run time, which manifests as either a kernel panic or thread getting killed. A proposed warning in clang aims to catch these at compile time, which reveals: drivers/gpu/drm/meson/meson_encoder_cvbs.c:211:16: error: incompatible function pointer types initializing 'enum drm_mode_status (*)(struct drm_bridge *, const struct drm_display_info *, const struct drm_display_mode *)' with an expression of type 'int (struct drm_bridge *, const struct drm_display_info *, const struct drm_display_mode *)' [-Werror,-Wincompatible-function-pointer-types-strict] .mode_valid = meson_encoder_cvbs_mode_valid, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1 error generated. ->mode_valid() in 'struct drm_bridge_funcs' expects a return type of 'enum drm_mode_status', not 'int'. Adjust the return type of meson_encoder_cvbs_mode_valid() to match the prototype's to resolve the warning and CFI failure.
