2022-02-01brcmfmac: pcie: Fix crashes due to early IRQsHector Martin1-3/+13
The driver was enabling IRQs before the message processing was initialized. This could cause IRQs to come in too early and crash the driver. Instead, move the IRQ enable and hostready to a bus preinit function, at which point everything is properly initialized. Fixes: 9e37f045d5e7 ("brcmfmac: Adding PCIe bus layer support.")

2022-02-01brcmfmac: pcie: Replace brcmf_pcie_copy_mem_todev with memcpy_toioHector Martin1-44/+4
The alignment check was wrong (e.g. & 4 instead of & 3), and the logic was also inefficient if the length was not a multiple of 4, since it would needlessly fall back to copying the entire buffer bytewise. We already have a perfectly good memcpy_toio function, so just call that instead of rolling our own copy logic here. brcmf_pcie_init_ringbuffers was already using it anyway.

2022-02-01drm/i915: Split intel_cpu_transcoder_set_m_n() into M1/N1 vs. M2/N2 variantsVille Syrjälä5-45/+54
Make things a bit more explicit by splitting intel_cpu_transcoder_set_m_n() into separate variants for M1/N1 vs. M2/N2. Makes the DRRS M/N programming at least more obvious. Note that for the MST and DRRS cases we don't need to call the M2/N2 variant at all since the transcoders that support those do not have the M2/N2 registers. Same could be said for i9xx_crtc_enable() but I want to do a higher level code sharing between that valleyview_crtc_enable() later in which case we do need the M2/N2 variant. This is also why I keep the transcoder_has_m2_n2() in intel_cpu_transcoder_set_m2_n2() so the caller doesn't have necessarily care what the chosen transcoder supports.

2022-02-01drm/i915/pmu: Fix KMD and GuC race on accessing busynessUmesh Nerlige Ramappa1-4/+54
GuC updates shared memory and KMD reads it. Since this is not synchronized, we run into a race where the value read is inconsistent. Sometimes the inconsistency is in reading the upper MSB bytes of the last_switch_in value. 2 types of cases are seen - upper 8 bits are zero and upper 24 bits are zero. Since these are non-zero values, it is not trivial to determine validity of these values. Instead we read the values multiple times until they are consistent. In test runs, 3 attempts results in consistent values. The upper bound is set to 6 attempts and may need to be tuned as per any new occurences. Since the duration that gt is parked can vary, the patch also updates the gt timestamp on unpark before starting the worker. v2: - Initialize i - Use READ_ONCE to access engine record Fixes: 77cdd054dd2c ("drm/i915/pmu: Connect engine busyness stats from GuC to pmu") Signed-off-by: Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com> Reviewed-by: Alan Previn <alan.previn.teres.alexis@intel.com> Signed-off-by: John Harrison <John.C.Harrison@Intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220125020124.788679-2-umesh.nerlige.ramappa@intel.com (cherry picked from commit 512712a824de9b856a4e61343e3e4390eba2c391) Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
