It was noticed when setting the Panfrost's DVFS device to the performant governor, GPU frequency as reported by fdinfo had dropped to 0 permamently. There are two separate issues causing this behaviour: - Not initialising the device's current_frequency variable to its original value during device probe(). - Updating said variable in Panfrost devfreq's get_dev_status() rather than after the new OPP's frequency had been retrieved in target(), which meant the old frequency would be assigned instead.

This is a hack around a bug exposed with the GSP code, I'm not sure what is happening exactly, but it appears some of our flushes don't result in proper tlb invalidation for out BAR2 and we get a BAR2 fault from GSP and it all dies. Signed-off-by:

Fake flexible arrays (zero-length and one-element arrays) are deprecated, and should be replaced by flexible-array members. So, replace zero-length array with a flexible-array member in `struct PACKED_REGISTRY_TABLE`. Also annotate array `entries` with `__counted_by()` to prepare for the coming implementation by GCC and Clang of the `__counted_by` attribute. Flexible array members annotated with `__counted_by` can have their accesses bounds-checked at run-time via `CONFIG_UBSAN_BOUNDS` (for array indexing) and `CONFIG_FORTIFY_SOURCE` (for strcpy/memcpy-family functions). This fixes multiple -Warray-bounds warnings: drivers/gpu/drm/nouveau/nvkm/subdev/gsp/r535.c:1069:29: warning: array subscript 0 is outside array bounds of 'PACKED_REGISTRY_ENTRY[0]' [-Warray-bounds=] drivers/gpu/drm/nouveau/nvkm/subdev/gsp/r535.c:1070:29: warning: array subscript 0 is outside array bounds of 'PACKED_REGISTRY_ENTRY[0]' [-Warray-bounds=] drivers/gpu/drm/nouveau/nvkm/subdev/gsp/r535.c:1071:29: warning: array subscript 0 is outside array bounds of 'PACKED_REGISTRY_ENTRY[0]' [-Warray-bounds=] drivers/gpu/drm/nouveau/nvkm/subdev/gsp/r535.c:1072:29: warning: array subscript 0 is outside array bounds of 'PACKED_REGISTRY_ENTRY[0]' [-Warray-bounds=] While there, also make use of the struct_size() helper, and address checkpatch.pl warning: WARNING: please, no spaces at the start of a line This results in no differences in binary output.

Some panel devices already depend on DRM device, like the panel in arch/arm/boot/dts/st/ste-ux500-samsung-skomer.dts, because DRM device is the ancestor of those panel devices. device_link_add() would fail by returning a NULL pointer for those panel devices because of the existing dependency. So, check the dependency by calling device_is_dependent() before adding or deleting device link between panel device and DRM device so that the link is managed only for independent panel devices.

This probably isn't the ideal fix, but we ended up using chids sparsely, and lots of things rely on indexing into the full range, so just allocate the full range up front. The GSP code fixes 8 channels into a userd page, but we end up using a single userd page per channel so end up sparsely using the range. Fixes a few crashes seen with multiple channels.

The refresh reported by modetest is 60.46Hz, and the actual measurement is 60.01Hz, which is outside the expected tolerance. Adjust hporch and pixel clock to fix it. After repair, modetest and actual measurement were all 60.01Hz. Modetest refresh = Pixel CLK/ htotal* vtotal, but measurement frame rate is HS->LP cycle time(Vblanking). Measured frame rate is not only affecte by Htotal/Vtotal/pixel clock, also affected by Lane-num/PixelBit/LineTime /DSI CLK. Assume that the DSI controller could not make the mode that we requested(presumably it's PLL couldn't generate the exact pixel clock?). If you use a different DSI controller, you may need to readjust these parameters. Now this panel looks like it's only used by me on the MTK platform, so let's change this set of parameters.

Many user-space compositors fail with mode setting if a CRTC has more than one connected connector. This is the case with the BMC on Aspeed systems. Work around this problem by setting the BMC's connector status to disconnected when the physical connector has a display attached. This way compositors will only see one connected connector at a time; either the physical one or the BMC. Suggested-by:

There is no need to call MMIO reset using VPU_37XX_BUTTRESS_VPU_IP_RESET register. IP will be reset by FLR or by entering d0i3. Also IP reset during power_up is not needed as the VPU is already in reset. Removing MMIO reset improves stability as it a partial device reset that is not safe in some corner cases. This change also brings back ivpu_boot_pwr_domain_disable() that helps to properly power down VPU when it is hung by a buggy workload. Signed-off-by:

The r535_gsp_cmdq_get() function returns error pointers but this code checks for NULL. Also we need to propagate the error pointer back to the callers in r535_gsp_rpc_get(). Returning NULL will lead to a NULL pointer dereference. Fixes: 176fdcbd ("drm/nouveau/gsp/r535: add support for booting GSP-RM") Signed-off-by:

There are the same prototypes in asm/kprobes.h for some architectures, but some of them are missing the prototype and it causes a warning. So move the prototype into linux/kprobes.h. - tracing: Fix to check the tracepoint event and return event at parsing stage. The tracepoint event doesn't support %return but if $retval exists, it will be converted to %return silently. This finds that case and rejects it. - tracing: Fix the order of the descriptions about the parameters of __kprobe_event_gen_cmd_start() to be consistent with the argument list of the function. * tag 'probes-fixes-v6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing/kprobes: Fix the order of argument descriptions tracing: fprobe-event: Fix to check tracepoint event and return kprobes: unify kprobes_exceptions_nofify() prototypes lib: test_objpool: make global variables static Documentation: tracing: Add a note about argument and retval access
