[Why] call stack of amdgpu dsc mst pbn, slot num calculation is as below: -compute_bpp_x16_from_target_bandwidth -decide_dsc_target_bpp_x16 -setup_dsc_config -dc_dsc_compute_bandwidth_range -compute_mst_dsc_configs_for_link -compute_mst_dsc_configs_for_state from pbn -> dsc target bpp_x16 bpp_x16 is calulated by compute_bpp_x16_from_target_bandwidth. Beside pixel clock and bpp, num_slices_h and bpp_increment_div will also affect bpp_x16. from dsc target bpp_x16 -> pbn within dm_update_mst_vcpi_slots_for_dsc, pbn = drm_dp_calc_pbn_mode(clock, bpp_x16, true); drm_dp_calc_pbn_mode(int clock, int bpp, bool dsc) { return DIV_ROUND_UP_ULL(mul_u32_u32(clock * (bpp / 16), 64 * 1006), 8 * 54 * 1000 * 1000); } bpp / 16 trunc digits after decimal point. This will cause calculation delta. drm_dp_calc_pbn_mode does not have other informations, like num_slices_h, bpp_increment_div. therefore, it does not do revese calcuation properly from bpp_x16 to pbn. pbn from drm_dp_calc_pbn_mode is less than pbn from compute_mst_dsc_configs_for_state. This cause not enough mst slot allocated to display. display could not visually light up.

On Carrizo/Stoney systems we set backlight through panel_cntl, i.e. directly via the PWM registers, if DMCU is not initialized. We always read it back through ABM registers which leads to a mismatch and forces atomic_commit to program the backlight each time. Instead make sure we use the same logic for backlight readback, i.e. read it from panel_cntl if DMCU is not initialized. We also need to remove some extraneous and incorrect calculations at the end of dce_get_16_bit_backlight_from_pwm.

On some GPUs the PCIe atomic requirement for KFD depends on the MEC firmware version. Add a firmware version check for this. The minimum firmware version that works without atomics can be updated in the device_info structure for each GPU type. Move PCIe atomic detection from kgd2kfd_probe into kgd2kfd_device_init because the MEC firmware is not loaded yet at the probe stage. Signed-off-by:

Add manual sclk/vddc setting supoort via pp_od_clk_voltage sysfs to maintain consistency with other asics. As cyan skillfish doesn't support DPM, there is only a single frequency and voltage to adjust. v2: maintain consistency and add command guide. v3: adjust user settings storage and coding style. Command guide: echo vc point sclk vddc > pp_od_clk_voltage "vc" - sclk voltage curve "point" - must be 0 "sclk" - target value of sclk(MHz), should be in safe range "vddc" - target value of vddc(mV), a 6.25(mV) stepping is recommended and should be in safe range (the real vddc is an approximation of target value) echo c > pp_od_clk_voltage "c" - commit the changes of sclk and vddc, only after the commit command, the target values set by "vc" command will take effect echo r > pp_od_clk_voltage "r" - reset sclk and vddc to default value, a subsequent commit command is needed to take effect Example: 1) Check default sclk and vddc $ cat pp_od_clk_voltage OD_SCLK: 0: 1800Mhz * OD_VDDC: 0: 862mV * OD_RANGE: SCLK: 1000Mhz 2000Mhz VDDC: 700mV 1129mV 2) Set sclk to 1500MHz and vddc to 700mV $ echo vc 0 1500 700 > pp_od_clk_voltage $ echo c > pp_od_clk_voltage $ cat pp_od_clk_voltage OD_SCLK: 0: 1500Mhz * OD_VDDC: 0: 693mV * OD_RANGE: SCLK: 1000Mhz 2000Mhz VDDC: 700mV 1129mV 3) Reset sclk and vddc to default $ echo r > pp_od_clk_voltage $ echo c > pp_od_clk_voltage $ cat pp_od_clk_voltage OD_SCLK: 0: 1800Mhz * OD_VDDC: 0: 874mV * OD_RANGE: SCLK: 1000Mhz 2000Mhz VDDC: 700mV 1129mV NOTE: We don't specify an explicit safe range, you can set any values between min and max at your own risk.

In amdgpu_dm_atomic_check, dc_validate_global_state is called. On failure this logs a warning to the kernel journal. However warnings shouldn't be used for atomic test-only commit failures: user-space might be perfoming a lot of atomic test-only commits to find the best hardware configuration. Downgrade the log to a regular DRM atomic message. While at it, use the new device-aware logging infrastructure. This fixes error messages in the kernel when running gamescope [1].

Currently perf saves a build-id with size but old versions assumes the size of 20. In case the build-id is less than 20 (like for MD5), it'd fill the rest with 0s. I saw a problem when old version of perf record saved a binary in the build-id cache and new version of perf reads the data. The symbols should be read from the build-id cache (as the path no longer has the same binary) but it failed due to mismatch in the build-id. symsrc__init: build id mismatch for /home/namhyung/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf. The build-id event in the data has 20 byte build-ids, but it saw a different size (16) when it reads the build-id of the elf file in the build-id cache. $ readelf -n ~/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf Displaying notes found in: .note.gnu.build-id Owner Data size Description GNU 0x00000010 NT_GNU_BUILD_ID (unique build ID bitstring) Build ID: 53e4c2f42a4c61a2d632d92a72afa08f Let's fix this by allowing trailing zeros if the size is different.

A config terms list was spliced twice, resulting in a never-ending loop when the list was traversed. Fix by using list_splice_init() and copying and freeing the lists as necessary. This patch also depends on patch "perf tools: Factor out copy_config_terms() and free_config_terms()" Example on ADL: Before: # perf record -e '{intel_pt//,cycles/aux-sample-size=4096/pp}' uname & # jobs [1]+ Running perf record -e "{intel_pt//,cycles/aux-sample-size=4096/pp}" uname # perf top -E 10 PerfTop: 4071 irqs/sec kernel: 6.9% exact: 100.0% lost: 0/0 drop: 0/0 [4000Hz cycles], (all, 24 CPUs) --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- 97.60% perf [.] __evsel__get_config_term 0.25% [kernel] [k] kallsyms_expand_symbol.constprop.13 0.24% perf [.] kallsyms__parse 0.15% [kernel] [k] _raw_spin_lock 0.14% [kernel] [k] number 0.13% [kernel] [k] advance_transaction 0.08% [kernel] [k] format_decode 0.08% perf [.] map__process_kallsym_symbol 0.08% perf [.] rb_insert_color 0.08% [kernel] [k] vsnprintf exiting. # kill %1 After: # perf record -e '{intel_pt//,cycles/aux-sample-size=4096/pp}' uname & Linux [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.060 MB perf.data ] # perf script | head perf-exec 604 [001] 1827.312293: psb: psb offs: 0 ffffffffb8415e87 pt_config_start+0x37 ([kernel.kallsyms]) perf-exec 604 1827.312293: 1 branches: ffffffffb856a3bd event_sched_in.isra.133+0xfd ([kernel.kallsyms]) => ffffffffb856a9a0 perf_pmu_nop_void+0x0 ([kernel.kallsyms]) perf-exec 604 1827.312293: 1 branches: ffffffffb856b10e merge_sched_in+0x26e ([kernel.kallsyms]) => ffffffffb856a2c0 event_sched_in.isra.133+0x0 ([kernel.kallsyms]) perf-exec 604 1827.312293: 1 branches: ffffffffb856a45d event_sched_in.isra.133+0x19d ([kernel.kallsyms]) => ffffffffb8568b80 perf_event_set_state.part.61+0x0 ([kernel.kallsyms]) perf-exec 604 1827.312293: 1 branches: ffffffffb8568b86 perf_event_set_state.part.61+0x6 ([kernel.kallsyms]) => ffffffffb85662a0 perf_event_update_time+0x0 ([kernel.kallsyms]) perf-exec 604 1827.312293: 1 branches: ffffffffb856a35c event_sched_in.isra.133+0x9c ([kernel.kallsyms]) => ffffffffb8567610 perf_log_itrace_start+0x0 ([kernel.kallsyms]) perf-exec 604 1827.312293: 1 branches: ffffffffb856a377 event_sched_in.isra.133+0xb7 ([kernel.kallsyms]) => ffffffffb8403b40 x86_pmu_add+0x0 ([kernel.kallsyms]) perf-exec 604 1827.312293: 1 branches: ffffffffb8403b86 x86_pmu_add+0x46 ([kernel.kallsyms]) => ffffffffb8403940 collect_events+0x0 ([kernel.kallsyms]) perf-exec 604 1827.312293: 1 branches: ffffffffb8403a7b collect_events+0x13b ([kernel.kallsyms]) => ffffffffb8402cd0 collect_event+0x0 ([kernel.kallsyms]) Fixes: 30def61f ("perf parse-events Create two hybrid cache events") Fixes: 94da591b ("perf parse-events Create two hybrid raw events") Fixes: 9cbfa2f6 ("perf parse-events Create two hybrid hardware events") Signed-off-by:Adrian Hunter <adrian.hunter@intel.com> Acked-by:
