2022-07-25drm/amd/display: Create dcn321_fpu fileRodrigo Siqueira

2022-07-25drm/amd/pm: revise the driver reloading fix for SMU 13.0.0 and 13.0.7Evan Quan
The current approach breaks S3/S4 as asic reset is needed for them. And putting SMU out of service(via SMU_MSG_PrepareMp1ForUnload) will make that(asic reset) failed. Considering with current designs, there is actually also asic reset involved on driver reloading. That can make asic back to a clean state. So, the SMU_MSG_PrepareMp1ForUnload operation will be not so necessary. Thus we will just drop the SMU_MSG_PrepareMp1ForUnload operation. We may revise the whole driver reloading sequences when there is a better design.

[why] Unbounded request logic in resource/DML has some issues where unbounded request is being enabled incorrectly. SW today enables unbounded request unconditionally in hardware, on the assumption that HW can always support it in single pipe scenarios. This worked until now because the same assumption is made in DML. A new DML update is needed to fix a bug, where there are single pipe scenarios where unbounded cannot be enabled, and this change in DML needs to be ported in, and dcn32 resource logic fixed.

2022-07-25drm/amd/debugfs: Expose GFXOFF state to userspaceAndré Almeida
GFXOFF has two different "state" values: one to define if the GPU is allowed/disallowed to enter GFXOFF, usually called state; and another one to define if currently GFXOFF is being used, usually called status. Even when GFXOFF is allowed, GPU firmware can decide to not used it accordingly to the GPU load. Userspace can allow/disallow GPUs to enter into GFXOFF via debugfs. The kernel maintains a counter of requests for GFXOFF (gfx_off_req_count) that should be decreased to allow GFXOFF and increased to disallow. The issue with this interface is that userspace can't be sure if GFXOFF is currently allowed. Even by checking amdgpu_gfxoff file, one might get an ambiguous 2, that means that GPU is currently out of GFXOFF, but that can be either because it's currently disallowed or because it's allowed but given the current GPU load it's enabled. Then, userspace needs to rely on the fact that GFXOFF is enabled by default on boot and to track this information. To make userspace life easier and GFXOFF more reliable, return the current state of GFXOFF to userspace when reading amdgpu_gfxoff with the same semantics of writing: 0 means not allowed, not 0 means allowed. Expose the current status of GFXOFF through a new file, amdgpu_gfxoff_status. Signed-off-by: André Almeida <andrealmeid@igalia.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

As a result, this file becomes very large since it comprises multiple abstractions such as CRTC manipulation. [How] This commit extracts the CRTC code to its specific file named amdgpu_dm_crtc. This change does not change anything inside the functions; the only exception is converting some static functions to a global function. v2: fix ifdef merge mix up (Alex) Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Reviewed-by: Harry Wentland <Harry.Wentland@amd.com> Acked-by: Alan Liu <HaoPing.Liu@amd.com> Signed-off-by: Rodrigo Siqueira <Rodrigo.Siqueira@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

It looks like their urgency is decreasing so it seems like we've managed to catch whatever snafus the limited -rc testing has exposed. Maybe we're getting ready... :) - Make retbleed mitigations 64-bit only (32-bit will need a bit more work if even needed, at all). - Prevent return thunks patching of the LKDTM modules as it is not needed there - Avoid writing the SPEC_CTRL MSR on every kernel entry on eIBRS parts - Enhance error output of apply_returns() when it fails to patch a return thunk - A sparse fix to the sev-guest module - Protect EFI fw calls by issuing an IBPB on AMD" * tag 'x86_urgent_for_v5.19_rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/speculation: Make all RETbleed mitigations 64-bit only lkdtm: Disable return thunks in rodata.c x86/bugs: Warn when "ibrs" mitigation is selected on Enhanced IBRS parts x86/alternative: Report missing return thunk details virt: sev-guest: Pass the appropriate argument type to iounmap() x86/amd: Use IBPB for firmware calls

2022-07-23drm/bridge: ti-sn65dsi86: Use dev_err_probe() to avoid polluting the logJavier Martinez Canillas
If devm_drm_of_get_bridge() can't find the connected bridge, it returns an ERR_PTR(-EPROBE_DEFER) to indicate that the probe should be deferred. But this path also prints an error message, which pollutes the kernel log since is printed on every probe deferral, i.e: $ dmesg | grep "failed to create panel bridge" | wc -l 38 Signed-off-by: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: Neil Armstrong <narmstrong@baylibre.com> Reviewed-by: Andrzej Hajda <andrzej.hajda@intel.com> Reviewed-by: Douglas Anderson <dianders@chromium.org> Link: https://patchwork.freedesktop.org/patch/msgid/20220722074755.660258-1-javierm@redhat.com
