2020-05-21drm/amdgpu fix incorrect sysfs remove behavior for xgmiJack Zhang1-7/+16
Under xgmi setup,some sysfs fail to create for the second time of kmd driver loading. It's due to sysfs nodes are not removed appropriately in the last unlod time. Changes of this patch: 1. remove sysfs for dev_attr_xgmi_error 2. remove sysfs_link adev->dev->kobj with target name. And it only needs to be removed once for a xgmi setup 3. remove sysfs_link hive->kobj with target name In amdgpu_xgmi_remove_device: 1. amdgpu_xgmi_sysfs_rem_dev_info needs to be run per device 2. amdgpu_xgmi_sysfs_destroy needs to be run on the last node of device. v2: initialize array with memset Signed-off-by: Jack Zhang <Jack.Zhang1@amd.com> Reviewed-by: Hawking Zhang <Hawking.Zhang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2020-05-21drm/amd/display: Enable fp16 also on DCE-11.0 - DCE-12. (v2)Mario Kleiner2-2/+2
Testing on a Polaris11 gpu with DCE-11.2 suggests that it seems to work fine there, so optimistically enable it for DCE-11 and later. v2: drop DCE 11.0 hunk. Carrizo (DCE 11.0) has a HW bug where FP16 scaling doesn't work. The upscale and downscale factors were intended to block those FP16 cases and reject the commit but nobody ever added those to atomic check. Once those are added to atomic check, this can be re-enabled.

When CONFIG_DRM_I915_DEBUG_GEM is not set, clang warns: drivers/gpu/drm/i915/gvt/scheduler.c:884:1: warning: function 'check_shadow_context_ppgtt' is not needed and will not be emitted [-Wunneeded-internal-declaration] check_shadow_context_ppgtt(struct execlist_ring_context *c, struct intel_vgpu_mm *m) ^ 1 warning generated. This warning is similar to -Wunused-function but rather than warning that the function is completely unused, it warns that it is used in some expression within the file but that expression will be evaluated to a constant or be optimized away in the final assembly, essentially making it appeared used but really isn't. Usually, this happens when a function or variable is only used in sizeof, where it will appear to be used but will be evaluated at compile time and not be required to be emitted. In this case, the function is only used in GEM_BUG_ON, which is defined as BUILD_BUG_ON_INVALID, which intentionally follows this pattern. To fix this warning, add __maybe_unused to make it clear that this is intentional depending on the configuration.

2020-05-18drm/amdgpu: Add autodump debugfs node for gpu reset v8Jiange Zhao4-1/+87
When GPU got timeout, it would notify an interested part of an opportunity to dump info before actual GPU reset. A usermode app would open 'autodump' node under debugfs system and poll() for readable/writable. When a GPU reset is due, amdgpu would notify usermode app through wait_queue_head and give it 10 minutes to dump info. After usermode app has done its work, this 'autodump' node is closed. On node closure, amdgpu gets to know the dump is done through the completion that is triggered in release(). There is no write or read callback because necessary info can be obtained through dmesg and umr. Messages back and forth between usermode app and amdgpu are unnecessary. v2: (1) changed 'registered' to 'app_listening' (2) add a mutex in open() to prevent race condition v3 (chk): grab the reset lock to avoid race in autodump_open, rename debugfs file to amdgpu_autodump, provide autodump_read as well, style and code cleanups v4: add 'bool app_listening' to differentiate situations, so that the node can be reopened; also, there is no need to wait for completion when no app is waiting for a dump. v5: change 'bool app_listening' to 'enum amdgpu_autodump_state' add 'app_state_mutex' for race conditions: (1)Only 1 user can open this file node (2)wait_dump() can only take effect after poll() executed. (3)eliminated the race condition between release() and wait_dump() v6: removed 'enum amdgpu_autodump_state' and 'app_state_mutex' removed state checking in amdgpu_debugfs_wait_dump Improve on top of version 3 so that the node can be reopened. v7: move reinit_completion into open() so that only one user can open it. v8: remove complete_all() from amdgpu_debugfs_wait_dump().

2020-05-18drm/exynos: dsi: Remove bridge node reference in error handling path in ↵Christophe JAILLET1-5/+15
probe function 'exynos_dsi_parse_dt()' takes a reference to 'dsi->in_bridge_node'. This must be released in the error handling path. In order to do that, add an error handling path and move the 'exynos_dsi_parse_dt()' call from the beginning to the end of the probe function to ease the error handling path. This function only sets some variables which are used only in the 'transfer' function. The call chain is: .transfer --> exynos_dsi_host_transfer --> exynos_dsi_init --> exynos_dsi_enable_clock (use burst_clk_rate and esc_clk_rate) --> exynos_dsi_set_pll (use pll_clk_rate) While at it, also handle cases where 'component_add()' fails.

Runtime power management is essential for the Exynos Mixer driver operation. It should be enabled before adding its DRM component, because in some cases (when deferred probe takes place due to the IOMMU availability) the DRM driver might be initialized directly from the Mixer's component_add() call, what results in starting the driver operation without enabling the runtime power management.

2020-05-14drm/amdgpu: turn back rlcg write for gfx_v10Yintian Tao1-8/+6
There is no need to use amdgpu_mm_wreg_mmio_rlc() during initialization time because this interface is only designed for debugfs case to access the registers which are only permitted by RLCG during run-time. Therefore, turn back rlcg write for gfx_v10. If we not turn back it, it will raise amdgpu load failure.

2020-05-14drm/i915: Extract i915_cs_timestamp_{ns_to_ticks,tick_to_ns}()Ville Syrjälä5-10/+17
Pull the code to do the CS timestamp ns<->ticks conversion into helpers and use them all over. The check in i915_perf_noa_delay_set() seems a bit dubious, so we switch it to do what I assume it wanted to do all along (ie. make sure the resulting delay in CS timestamp ticks doesn't exceed 32bits)?
