Add support for DP-HDMI2.1 PCON From the series cover letter: This patch series attempts to add support for a DP-HDMI2.1 Protocol Convertor. The VESA spec for the HDMI2.1 PCON are proposed in Errata E5 to DisplayPort_v2.0: https://vesa.org/join-vesamemberships/member-downloads/?action=stamp&fileid=42299 The details are mentioned in: VESA DP-to-HDMI PCON Specification Standalone Document https://groups.vesa.org/wg/DP/document/15651 This series starts with adding support for FRL (Fixed Rate Link) Training between the PCON and HDMI2.1 sink. As per HDMI2.1 specification, a new data-channel or lane is added in FRL mode, by repurposing the TMDS clock Channel. Through FRL, higher bit-rate can be supported, ie. up to 12 Gbps/lane (48 Gbps over 4 lanes). With these patches, the HDMI2.1 PCON can be configured to achieve FRL training based on the maximum FRL rate supported by the panel, source and the PCON. The approach is to add the support for FRL training between PCON and HDMI2.1 sink and gradually add other blocks for supporting higher resolutions and other HDMI2.1 features, that can be supported by pcon for the sources that do not natively support HDMI2.1. This is done before the DP Link training between the source and PCON is started. In case of FRL training is not achieved, the PCON will work in the regular TMDS mode, without HDMI2.1 feature support. Any interruption in FRL training between the PCON and HDMI2.1 sink is notified through IRQ_HPD. On receiving the IRQ_HPD the concerned DPCD registers are read and FRL training is re-attempted. Currently, we have tested the FRL training and are able to enable 4K display with TGL Platform + Realtek PCON RTD2173 with HDMI2.1 supporting panel.

2021-01-06drm/amdgpu/display: drop DCN support for aarch64Alex Deucher13-73/+1
From Ard: "Simply disabling -mgeneral-regs-only left and right is risky, given that the standard AArch64 ABI permits the use of FP/SIMD registers anywhere, and GCC is known to use SIMD registers for spilling, and may invent other uses of the FP/SIMD register file that have nothing to do with the floating point code in question. Note that putting kernel_neon_begin() and kernel_neon_end() around the code that does use FP is not sufficient here, the problem is in all the other code that may be emitted with references to SIMD registers in it. So the only way to do this properly is to put all floating point code in a separate compilation unit, and only compile that unit with -mgeneral-regs-only." Disable support until the code can be properly refactored to support this properly on aarch64.

2021-01-06drm/amd/pm: improve the fine grain tuning function for RV/RV2/PCOXiaojian Du2-1/+59
This patch is to improve the fine grain tuning function for RV/RV2/PCO. The fine grain tuning function uses the sysfs node -- pp_od_clk_voltage to config gfxclk. Meanwhile, another sysfs node -- power_dpm_force_perfomance_level also affects the gfx clk. It will cause confusion when these two sysfs nodes works together. So this patch adds one flag to avoid this confusion, the flag will make these two sysfs nodes work separately. The flag is set as "disabled" by default, so the fine grain tuning function will be disabled by default. Only when power_dpm_force_perfomance_level is changed to "manual" mode, the flag will be set as "enabled", and the fine grain tuning function will be enabled. In other profile modes, including "auto", "high", "low", "profile_peak", "profile_standard", "profile_min_sclk", "profile_min_mclk", the flag will be set as "disabled", and the od range of fine grain tuning function will be restored default value.

2021-01-06drm/amd/pm: improve the fine grain tuning function for RV/RV2/PCOXiaojian Du2-17/+98
This patch is to improve the fine grain tuning function for RV/RV2/PCO. This patch adds two new commands: "restore" and "commit". This function uses the pp_od_clk_voltage sysfs file to configure the min and max value of gfx clock frequency manually or restore the default value. Command guide: echo "s level value" > pp_od_clk_voltage "s" - set the sclk frequency "level" - 0 or 1, "0" represents the min value, "1" represents the max value "value" - the target value of sclk frequency, it should be limited in the safe range echo "r" > pp_od_clk_voltage "r" - reset the sclk frequency, restore the default value instantly echo "c" > pp_od_clk_voltage "c" - commit the min and max value of sclk frequency to the system only after the commit command, the target values set by "s" command will take effect. Example: 1)change power profile from "auto" to "manual" $ cat power_dpm_force_performance_level auto $ echo "manual" > power_dpm_force_performance_level $ cat power_dpm_force_performance_level manual 2)check the default sclk frequency $ cat pp_od_clk_voltage OD_SCLK: 0: 200Mhz 1: 1400Mhz OD_RANGE: SCLK: 200MHz 1400MHz 3)use "s" -- set command to configure the min and max sclk frequency $ echo "s 0 600" > pp_od_clk_voltage $ echo "s 1 1000" > pp_od_clk_voltage $ echo "c" > pp_od_clk_voltage $ cat pp_od_clk_voltage OD_SCLK: 0: 600Mhz 1: 1000Mhz OD_RANGE: SCLK: 200MHz 1400MHz 4)use "r" -- reset command to restore the min or max sclk frequency $ echo "r" > pp_od_clk_voltage $ cat pp_od_clk_voltage OD_SCLK: 0: 200Mhz 1: 1400Mhz OD_RANGE: SCLK: 200MHz 1400MHz Signed-off-by: Xiaojian Du <Xiaojian.Du@amd.com> Reviewed-by: Evan Quan <evan.quan@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2021-01-06drm/ttm: Remove pinned bos from LRU in ttm_bo_move_to_lru_tail() v2Lyude Paul1-1/+3

After some bisection and investigation, it appears this resulted from the recent changes to ttm_bo_move_to_lru_tail(). Previously when a buffer was pinned, the buffer would be removed from the LRU once ttm_bo_unreserve to maintain the LRU list when pinning or unpinning BOs. However, since: commit 3d1a88e1051f ("drm/ttm: cleanup LRU handling further") We've been exiting from ttm_bo_move_to_lru_tail() at the very beginning of the function if the bo we're looking at is pinned, resulting in the pinned BO never getting removed from the lru and as a result - causing issues when it eventually becomes time for eviction. So, let's fix this by calling ttm_bo_del_from_lru() from ttm_bo_move_to_lru_tail() in the event that we're dealing with a pinned buffer. v2 (chk): reduce to only the fixing one liner since we always want to call the callback whenever we would move on the LRU.

2021-01-06drm/v3d: Don't clear MMU control bits on exceptionPhil Elwell1-4/+1
MMU exception conditions are reported in the V3D_MMU_CTRL register as write-1-to-clear (W1C) bits. The MMU interrupt handling code clears any exceptions, but does so by masking out any other bits and writing the result back. There are some important control bits in that register, including MMU_ENABLE, so a safer approach is to simply write back the value just read unaltered.

BXT/APL has different isr/irr/hpd regs compared with other GEN9. If not setting these regs bits correctly according to the emulated monitor (currently a DP on PORT_B), although gvt still triggers a virtual HPD event, the guest driver won't detect a valid HPD pulse thus no full display detection will be executed to read the updated EDID.

2021-01-05drm/i915/rkl: new rkl ddc map for different PCHLee Shawn C2-0/+12
After boot into kernel. Driver configured ddc pin mapping based on predefined table in parse_ddi_port(). Now driver configure rkl ddc pin mapping depends on icp_ddc_pin_map[]. Then this table will give incorrect gmbus port number to cause HDMI can't work. Refer to commit cd0a89527d06 ("drm/i915/rkl: Add DDC pin mapping"). Create two ddc pin table for rkl TGP and CMP pch. Then HDMI can works properly on rkl. v2: update patch based on latest dinq branch. v3: update ddc table for RKL+TGP sku. RKL+CNP sku will load cnp_ddc_pin_map[] setting. v4: modify the if/else judgment to avoid nesting. v5: fix typo in v4.

2021-01-05drm/amdgpu: Add check to prevent IH overflowDefang Bo3-39/+71
Similar to commit <b82175750131>("drm/amdgpu: fix IH overflow on Vega10 v2"). When an ring buffer overflow happens the appropriate bit is set in the WPTR register which is also written back to memory. But clearing the bit in the WPTR doesn't trigger another memory writeback. So what can happen is that we end up processing the buffer overflow over and over again because the bit is never cleared. Resulting in a random system lockup because of an infinite loop in an interrupt handler.

2021-01-05drm/amdgpu/display: drop DCN support for aarch64Alex Deucher13-73/+1
From Ard: "Simply disabling -mgeneral-regs-only left and right is risky, given that the standard AArch64 ABI permits the use of FP/SIMD registers anywhere, and GCC is known to use SIMD registers for spilling, and may invent other uses of the FP/SIMD register file that have nothing to do with the floating point code in question. Note that putting kernel_neon_begin() and kernel_neon_end() around the code that does use FP is not sufficient here, the problem is in all the other code that may be emitted with references to SIMD registers in it. So the only way to do this properly is to put all floating point code in a separate compilation unit, and only compile that unit with -mgeneral-regs-only." Disable support until the code can be properly refactored to support this properly on aarch64.
