A faulty receiver might report an erroneous channel count. We should guard against reading beyond AUDIO_CHANNELS_COUNT as that would overflow the dpcd_pattern_period array. Signed-off-by:

Some initial settings now are not available from the atom data table. The assumption that !ps[0] || !ps[1] in amdgpu_atom_asic_init is not valid. In addition, driver needs to strictly follow atomfirmware structure (asic_init_parameters) to initialize parameters used to execute asic_init function, otherwise, the execution of asic_init would fail. This shall be applicable to all soc15 adapters,but let make the transition on soc21 first. Signed-off-by:

While technically Xen dom0 is a virtual machine too, it does have access to most of the hardware so it doesn't need to be considered a "passthrough". Commit b818a5d3 ("drm/amdgpu/gmc: use PCI BARs for APUs in passthrough") changed how FB is accessed based on passthrough mode. This breaks amdgpu in Xen dom0 with message like this: [drm:dc_dmub_srv_wait_idle [amdgpu]] *ERROR* Error waiting for DMUB idle: status=3 While the reason for this failure is unclear, the passthrough mode is not really necessary in Xen dom0 anyway. So, to unbreak booting affected kernels, disable passthrough mode in this case.

The logic to update the IO links when a KFD device is removed was not correct as it would miss updating the proximity domain values for some nodes where the node_from and node_to both were greater values than the proximity domain value of the KFD device being removed from topology.

All uses of the 'kfd->gtt_sa_bitmap' bitmap are protected with the 'kfd->gtt_sa_lock' mutex. So: - prefer the non-atomic '__set_bit()' function - use the non-atomic 'bitmap_[set|clear]()' functions instead of equivalent 'for' loops. These functions can work on several bits at a time Signed-off-by:Christophe JAILLET <christophe.jaillet@wanadoo.fr> Reviewed-by:

'kfd->gtt_sa_bitmap' is a bitmap. So use 'bitmap_zalloc()' to simplify code, improve the semantic and avoid some open-coded arithmetic in allocator arguments. Also change the corresponding 'kfree()' into 'bitmap_free()' to keep consistency. Signed-off-by:

From [1], I realized two other calls to dcn30 code are associated with FPU operations and are not protected by DC_FP_* macros: * dcn30_populate_dml_writeback_from_context() * dcn30_set_mcif_arb_params() So, since FPU-associated code is not fully isolated in dcn30, and dcn3.1.x reuses them, let's wrap their calls properly. Note: this patch complements the fix from [1]. [1] https://lore.kernel.org/amd-gfx/20220329082957.1662655-1-chandan.vurdigerenataraj@amd.com/Reviewed-by:
