[Intel-gfx] [PATCH v9 10/24] drm/i915/dsc: Define & Compute VESA DSC params
From: Gaurav K Singh This patches does the following: 1. This patch defines all the DSC parameters as per the VESA DSC specification. These are stored in the encoder and used to compute the PPS parameters to be sent to the Sink. 2. Compute all the DSC parameters which are derived from DSC state of intel_crtc_state. 3. Compute all parameters that are VESA DSC specific This computation happens in the atomic check phase during compute_config() to validate if display stream compression can be enabled for the requested mode. v8 (From Manasi): * DEBUG_KMS instead of DRM_ERROR for user triggerable errors (Ville) v7: (From Manasi) * Dont use signed int for rc_range_params (Manasi) * Mask the range_bpg_offset to use only 6 bits * Add SPDX identifier (Chris Wilson) v6 (From Manasi): * Add a check for line_buf_depth return value (Anusha) * Remove DRM DSC constants to different patch (Manasi) v5 (From Manasi): * Add logic to limit the max line buf depth for DSC 1.1 to 13 as per DSC 1.1 spec * Fix dim checkpatch warnings/checks v4 (From Gaurav): * Rebase on latest drm tip * rename variable name(Manasi) * Populate linebuf_depth variable(Manasi) v3 (From Gaurav): * Rebase my previous patches on top of Manasi's latest patch series * Using >>n rather than /2^n (Manasi) * Change the commit message to explain what the patch is doing(Gaurav) Fixed review comments from Ville: * Don't use macro TWOS_COMPLEMENT * Mention in comment about the source of RC params * Return directly from case statements * Using single asssignment for assigning rc_range_params * Using < Cc: Ville Syrjala Cc: Anusha Srivatsa Cc: Gaurav K Singh Signed-off-by: Gaurav K Singh Signed-off-by: Manasi Navare Co-developed-by: Manasi Navare Reviewed-by: Anusha Srivatsa --- drivers/gpu/drm/i915/Makefile | 3 +- drivers/gpu/drm/i915/intel_dp.c | 7 + drivers/gpu/drm/i915/intel_drv.h | 4 + drivers/gpu/drm/i915/intel_vdsc.c | 455 ++ include/drm/drm_dp_helper.h | 3 + 5 files changed, 471 insertions(+), 1 deletion(-) create mode 100644 drivers/gpu/drm/i915/intel_vdsc.c diff --git a/drivers/gpu/drm/i915/Makefile b/drivers/gpu/drm/i915/Makefile index 0ff878c994e2..8370b9de6e4f 100644 --- a/drivers/gpu/drm/i915/Makefile +++ b/drivers/gpu/drm/i915/Makefile @@ -157,7 +157,8 @@ i915-y += dvo_ch7017.o \ intel_sdvo.o \ intel_tv.o \ vlv_dsi.o \ - vlv_dsi_pll.o + vlv_dsi_pll.o \ + intel_vdsc.o # Post-mortem debug and GPU hang state capture i915-$(CONFIG_DRM_I915_CAPTURE_ERROR) += i915_gpu_error.o diff --git a/drivers/gpu/drm/i915/intel_dp.c b/drivers/gpu/drm/i915/intel_dp.c index 931c3c7e55c1..0bdaa6e848a9 100644 --- a/drivers/gpu/drm/i915/intel_dp.c +++ b/drivers/gpu/drm/i915/intel_dp.c @@ -1959,6 +1959,13 @@ static bool intel_dp_dsc_compute_config(struct intel_dp *intel_dp, return false; } } + if (intel_dp_compute_dsc_params(intel_dp, pipe_config) < 0) { + DRM_DEBUG_KMS("Cannot compute valid DSC parameters for Input Bpp = %d" + "Compressed BPP = %d\n", + pipe_config->pipe_bpp, + pipe_config->dsc_params.compressed_bpp); + return false; + } pipe_config->dsc_params.compression_enable = true; DRM_DEBUG_KMS("DP DSC computed with Input Bpp = %d " "Compressed Bpp = %d Slice Count = %d\n", diff --git a/drivers/gpu/drm/i915/intel_drv.h b/drivers/gpu/drm/i915/intel_drv.h index 10476fec9485..d6466c401358 100644 --- a/drivers/gpu/drm/i915/intel_drv.h +++ b/drivers/gpu/drm/i915/intel_drv.h @@ -1851,6 +1851,10 @@ uint16_t intel_dp_dsc_get_output_bpp(int link_clock, uint8_t lane_count, uint8_t intel_dp_dsc_get_slice_count(struct intel_dp *intel_dp, int mode_clock, int mode_hdisplay); +/* intel_vdsc.c */ +int intel_dp_compute_dsc_params(struct intel_dp *intel_dp, + struct intel_crtc_state *pipe_config); + static inline unsigned int intel_dp_unused_lane_mask(int lane_count) { return ~((1 << lane_count) - 1) & 0xf; diff --git a/drivers/gpu/drm/i915/intel_vdsc.c b/drivers/gpu/drm/i915/intel_vdsc.c new file mode 100644 index ..0a1918f2f643 --- /dev/null +++ b/drivers/gpu/drm/i915/intel_vdsc.c @@ -0,0 +1,455 @@ +// SPDX-License-Identifier: MIT +/* + * Copyright © 2018 Intel Corporation + * + * Author: Gaurav K Singh + * Manasi Navare + */ + +#include +#include +#include "i915_drv.h" +#include "intel_drv.h" + +enum ROW_INDEX_BPP { + ROW_INDEX_6BPP = 0, + ROW_INDEX_8BPP, + ROW_INDEX_10BPP, + ROW_INDEX_12BPP, + ROW_INDEX_15BPP, + MAX_ROW_INDEX +}; + +enum COLUMN_INDEX_BPC { + COLUMN_INDEX_8BPC = 0, + COLUMN_INDEX_10BPC, + COLUMN_INDEX_12BPC, + COLUMN_INDEX_14BPC, + COLUMN_INDEX_16BPC, +

Both 8 and 16 give different CRC's. I suspect it's because cairo handles the color values (which get passed as double) slightly differently internally, although I haven't ruled out a slight inaccuracy on the hardware side. Given the alpha problems on gen9/gen10, it wouldn't surprise me if it turns out that our hardware is also treating a 10bpc component of 0x3ff as 0.999 rather than 1.0.

Originally we wanted to draw a color into a plane's FB (with Cairo) and then compare the CRC to turning off all planes and just setting the CRTC background to the same color. However the precision and rounding of the color components causes the CRC's to come out differently, even though the end result is visually identical.

[Intel-gfx] [PATCH i-g-t v2] tests/kms_crtc_background_color: overhaul for latest ABI proposal (v2)
CRTC background color kernel patches were written about 2.5 years ago and floated on the upstream mailing list, but since no opensource userspace materialized, we never actually merged them. However the corresponding IGT test did get merged and has basically been dead code ever since. A couple years later we may finally be getting closer to landing the kernel patches (there's some interest in this functionality now from both the ChromeOS and Weston camps), so lets update the IGT test to match the latest proposed ABI, and to remove some of the cruft from the original test that wouldn't actually work. It's worth noting that we don't seem to be able to test this feature with CRC's. Originally we wanted to draw a color into a plane's FB (with Cairo) and then compare the CRC to turning off all planes and just setting the CRTC background to the same color. However the precision and rounding of the color components causes the CRC's to come out differently, even though the end result is visually identical. So at the moment this test is mainly useful for visual inspection in interactive mode. v2: - Swap red and blue ordering in property value to reflect change in v2 of kernel series.

[Intel-gfx] [PATCH v2 3/3] drm/i915/gen9+: Add support for pipe background color (v2)
Gen9+ platforms allow CRTC's to be programmed with a background/canvas color below the programmable planes. Let's expose this for use by compositors. v2: - Split out bgcolor sanitization and programming of csc/gamma bits to a separate patch that we can land before the ABI changes are ready to go in. (Ville) - Change a temporary variable name to be more consistent with other similar functions. (Ville) - Change register name to SKL_CANVAS for consistency with the CHV_CANVAS register.

[Intel-gfx] [PATCH v2 0/3] CRTC background color
This is a second revision of the series previously posted here: https://lists.freedesktop.org/archives/intel-gfx/2018-October/178202.html As noted before, this functionality adds new ABI so we need a userspace consumer ready before we merge the kernel work. My understanding is that some of the folks involved with ChromeOS are looking at this and that there's a ChromeOS userspace review happening at https://chromium-review.googlesource.com/c/chromium/src/+/1278858 Since there are a few Intel-specific background color changes that we want to make independently of the new ABI, I've separated those out into a new patch #1; we may want to consider landing that patch before the rest of the series since it fixes an inconsistency in how we currently program our hardware. On the i915-side of things, this series only deals with gen9+ at the moment. It looks like CHV may also have support for background color functionality, but I couldn't find the register layout details for that platform, so I haven't added support for it yet.

[Intel-gfx] [PATCH v2 2/3] drm: Add CRTC background color property (v2)
Some display controllers can be programmed to present non-black colors for pixels not covered by any plane (or pixels covered by the transparent regions of higher planes). Compositors that want a UI with a solid color background can potentially save memory bandwidth by setting the CRTC background property and using smaller planes to display the rest of the content. To avoid confusion between different ways of encoding RGB data, we define a standard 64-bit format that should be used for this property's value. Helper functions and macros are provided to generate and dissect values in this standard format with varying component precision values. v2: - Swap internal representation's blue and red bits to make it easier to read if printed out. (Ville) - Document bgcolor property in drm_blend.c. (Sean Paul) - s/background_color/bgcolor/ for consistency between property name and value storage field. (Sean Paul) - Add a convenience function to attach property to a given crtc.

We don't yet allow userspace to control the CRTC background color, but we should manually program the color to black to ensure the BIOS didn't leave us with some other color.

Something like the trick for device info > flags, but can it be made to generate a macro? I think not.. Are we shy of macro magic? Pfft. #undef INTEL_VGA_DEVICE #define INTEL_VGA_DEVICE(id, info) (id) static const u32 bdw_ult_ids[] = { INTEL_BDW_GT1_ULT_IDS(0), }; static const u32 bdw_ulx_ids[] = { INTEL_BDW_GT1_ULX_IDS(0), }; #undef INTEL_VGA_DEVICE Now you can add another mapping on top with pointers to similar arrays as above and corresponding subplatform bits. Just need to order the code to not clobber the real INTEL_VGA_DEVICE needs. We don't need to split the ult/ulx tables by platform either if we only care about the subplatform ult/ulx here, just need to remember add all ult/ulx in corresponding arrays.

For most quirks, it's up to the drivers to actually do something with that information anyway, so it'll still remain i915 specific.

Seems to be copied > from gm45 where it is a u16 parameter instead. A good question. My excuse is that I was expecting it to be a u16. The max value the registers can hold is 11 bits, so u16 would be more than enough for our needs. Looks like we store these as u32 in the struct as well so we end up wasting a bit of memory. I'll go write a patch to shrink it a bit. -- Ville Syrjälä Intel ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx

[Intel-gfx] [PATCH] drm/i915: Disable LP3 watermarks on all SNB machines
From: Ville Syrjälä I have a Thinkpad X220 Tablet in my hands that is losing vblank interrupts whenever LP3 watermarks are used. If I nudge the latency value written to the WM3 register just by one in either direction the problem disappears. That to me suggests that the punit will not enter the corrsponding powersave mode (MPLL shutdown IIRC) unless the latency value in the register matches exactly what we read from SSKPD. Ie. it's not really a latency value but rather just a cookie by which the punit can identify the desired power saving state. On HSW/BDW this was changed such that we actually just write the WM level number into those bits, which makes much more sense given the observed behaviour. We could try to handle this by disallowing LP3 watermarks only when vblank interrupts are enabled but we'd first have to prove that only vblank interrupts are affected, which seems unlikely. Also we can't grab the wm mutex from the vblank enable/disable hooks because those are called with various spinlocks held. Thus we'd have to redesigne the watermark locking. So to play it safe and keep the code simple we simply disable LP3 watermarks on all SNB machines. To do that we simply zero out the latency values for watermark level 3, and we adjust the watermark computation to check for that. The behaviour now matches that of the g4x/vlv/skl wm code in the presence of a zeroed latency value.

So why do we need (__port) < I915_MAX_PORTS ? We don't actually *need*. I only thought the fact that the type is not explicit but rather depends on the enum value, it would be to fragile and it would start to fail silently if we ever change that.

[Intel-gfx] [PATCH 1/3] drm/i915: Use explicit old crtc state in skl_compute_wm()
From: Ville Syrjälä skl_compute_wm() wants to compare the old and new watermarks. Currently it gets at the old watermarks via crtc->state, which is confusing since it can point at either the old or the new state depending on where in the sequence we are. In this case it is correct since we have not yet swapped the states, but let's make it super clear what this is doing by using the explicit old state.

It's perhaps too much duplication to create a device info for all these variants, but I think it would be possible to make the subplatform info table driven using macros defined in i915_pciids.h. It would be much nicer, but how would you do it? Perhaps my imagination is just strong enough today. Simply by splitting the id's into subplatform parts, for instance where we have today: #define INTEL_BDW_GT1_IDS(info) \ INTEL_VGA_DEVICE(0x1602, info), /* GT1 ULT */ \ INTEL_VGA_DEVICE(0x1606, info), /* GT1 ULT */ \ INTEL_VGA_DEVICE(0x160B, info), /* GT1 Iris */ \ INTEL_VGA_DEVICE(0x160E, info), /* GT1 ULX */ \ INTEL_VGA_DEVICE(0x160A, info), /* GT1 Server */ \ INTEL_VGA_DEVICE(0x160D, info) /* GT1 Workstation */ We'd split to: #define INTEL_BDW_GT1_ULT_IDS(info) \ INTEL_VGA_DEVICE(0x1602, info), /* GT1 ULT */ \ INTEL_VGA_DEVICE(0x1606, info), /* GT1 ULT */ \ #define INTEL_BDW_GT1_ULX_IDS(info) \ INTEL_VGA_DEVICE(0x160E, info), /* GT1 ULX */ \ #define INTEL_BDW_GT1_IDS(info) \ INTEL_VGA_DEVICE(0x160B, info), /* GT1 Iris */ \ INTEL_VGA_DEVICE(0x160A, info), /* GT1 Server */ \ INTEL_VGA_DEVICE(0x160D, info) /* GT1 Workstation */ Then in i915_pci.c, instead of: ... INTEL_BDW_GT1_IDS(_broadwell_gt1_info), ... We'd have: ... INTEL_BDW_GT1_ULT_IDS(_broadwell_gt1_info), INTEL_BDW_GT1_ULX_IDS(_broadwell_gt1_info), INTEL_BDW_GT1_IDS(_broadwell_gt1_info), ... And a separate table to map the id's to subplatform values. Hmm, but we would probably need to extrac the id's from the INTEL_BDW1_GT_IDS like macros so they can be used in this second site without the info parameter. Something like the trick for device info flags, but can it be made to generate a macro? I think not..

Ok, but are not dirty_pipes being recomputed for each commit wrt to the current HW state. Should dirty_pipes not be 0 at the start of compute_wm naturally due to it not being used before in the atomic commit sequence? -Chris ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx

I can't figure out what the problem really is here. Yes, it does look like we'd end up writing the watermarks twice for pipes that are getting enabled. But that should be safeish (apart from the whole "need PLANE_SURF write to atually arm the update" mess). Note that this whole code is getting nuked soon (I hope): https://patchwork.freedesktop.org/series/51878/ but in the meantime if there is a clear bug we probably want the fix in first so that it can be backported. So I think we need a clear analysis of the actual problem. -- Ville Syrjälä Intel ___ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
[Intel-gfx] [PATCH i-g-t 2/4] tests/gem_ctx_sseu: Dynamic (sub)slice programming tests
From: Lionel Landwerlin Verify that the per-context dynamic SSEU uAPI works as expected. To achieve that, in the absence of a better mechamism, we read the value of PWR_CLK_STATE register, or use MI_SET_PREDICATE on platforms before Cannonlake. This register is written to by the GPU on context restore so this way we verify i915 is correctly updating the context image in all circumstances. v2: Add subslice tests (Lionel) Use MI_SET_PREDICATE for further verification when available (Lionel) v3: Rename to gem_ctx_rpcs (Lionel) v4: Update kernel API (Lionel) Add 0 value test (Lionel) Exercise invalid values (Lionel) v5: Add perf tests (Lionel) v6: Add new sysfs entry tests (Lionel) v7: Test rsvd fields Update for kernel series changes v8: Drop test_no_sseu_support() test (Kelvin) Drop drm_intel_*() apis (Chris) v9: by Chris: Drop all do_ioctl/do_ioctl_err() Use gem_context_[gs]et_param() Use gem_read() instead of mapping memory by Lionel: Test dynamic sseu on/off more Tvrtko Ursulin: v10: * Various style tweaks and refactorings. * New test coverage. v11: * Change platform support to just Gen11. * Simplify availability test. (Chris Wilson) * More invalid pointer tests. (Chris Wilson) v12: * Fix MAP_FIXED use (doh!). * Fix get/set copy errors. * Drop supported platform test. (Chris Wilson) * Add mmap__gtt test.

[Intel-gfx] [PATCH 4/6] drm/i915: Add timeline barrier support
From: Tvrtko Ursulin Timeline barrier allows serialization between different timelines. After calling i915_timeline_set_barrier with a request, all following submissions on this timeline will be set up as depending on this request, or barrier. Once the barrier has been completed it automatically gets cleared and things continue as normal. This facility will be used by the upcoming context SSEU code. v2: * Assert barrier has been retired on timeline_fini. (Chris Wilson) * Fix mock_timeline.

[Intel-gfx] [PATCH 3/6] drm/i915/perf: lock powergating configuration to default when active
From: Lionel Landwerlin If some of the contexts submitting workloads to the GPU have been configured to shutdown slices/subslices, we might loose the NOA configurations written in the NOA muxes. One possible solution to this problem is to reprogram the NOA muxes when we switch to a new context. We initially tried this in the workaround batchbuffer but some concerns where raised about the cost of reprogramming at every context switch. This solution is also not without consequences from the userspace point of view. Reprogramming of the muxes can only happen once the powergating configuration has changed (which happens after context switch). This means for a window of time during the recording, counters recorded by the OA unit might be invalid. This requires userspace dealing with OA reports to discard the invalid values. Minimizing the reprogramming could be implemented by tracking of the last programmed configuration somewhere in GGTT and use MI_PREDICATE to discard some of the programming commands, but the command streamer would still have to parse all the MI_LRI instructions in the workaround batchbuffer. Another solution, which this change implements, is to simply disregard the user requested configuration for the period of time when i915/perf is active. There is no known issue with this apart from a performance penality for some media workloads that benefit from running on a partially powergated GPU. We already prevent RC6 from affecting the programming so it doesn't sound completely unreasonable to hold on powergating for the same reason. v2: Leave RPCS programming in intel_lrc.c (Lionel) v3: Update for s/union intel_sseu/struct intel_sseu/ (Lionel) More to_intel_context() (Tvrtko) s/dev_priv/i915/ (Tvrtko) Tvrtko Ursulin: v4: * Rebase for make_rpcs changes. v5: * Apply OA restriction from make_rpcs directly. v6: * Rebase for context image setup changes. v7: * Move stream assignment before metric enable. v8-9: * Rebase.

[Intel-gfx] [PATCH 5/6] drm/i915: Expose RPCS (SSEU) configuration to userspace (Gen11 only)
From: Tvrtko Ursulin We want to allow userspace to reconfigure the subslice configuration on a per context basis. This is required for the functional requirement of shutting down non-VME enabled sub-slices on Gen11 parts. To do so, we expose a context parameter to allow adjustment of the RPCS register stored within the context image (and currently not accessible via LRI). If the context is adjusted before first use or whilst idle, the adjustment is for "free"; otherwise if the context is active we queue a request to do so (using the kernel context), following all other activity by that context, which is also marked as barrier for all following submission against the same context. Since the overhead of device re-configuration during context switching can be significant, especially in multi-context workloads, we limit this new uAPI to only support the Gen11 VME use case. In this use case either the device is fully enabled, and exactly one slice and half of the subslices are enabled. Example usage: struct drm_i915_gem_context_param_sseu sseu = { }; struct drm_i915_gem_context_param arg = { .param = I915_CONTEXT_PARAM_SSEU, .ctx_id = gem_context_create(fd), .size = sizeof(sseu), .value = to_user_pointer() }; /* Query device defaults. */ gem_context_get_param(fd, ); /* Set VME configuration on a 1x6x8 part. */ sseu.slice_mask = 0x1; sseu.subslice_mask = 0xe0; gem_context_set_param(fd, ); v2: Fix offset of CTX_R_PWR_CLK_STATE in intel_lr_context_set_sseu() (Lionel) v3: Add ability to program this per engine (Chris) v4: Move most get_sseu() into i915_gem_context.c (Lionel) v5: Validate sseu configuration against the device's capabilities (Lionel) v6: Change context powergating settings through MI_SDM on kernel context (Chris) v7: Synchronize the requests following a powergating setting change using a global dependency (Chris) Iterate timelines through dev_priv.gt.active_rings (Tvrtko) Disable RPCS configuration setting for non capable users (Lionel/Tvrtko) v8: s/union intel_sseu/struct intel_sseu/ (Lionel) s/dev_priv/i915/ (Tvrtko) Change uapi class/instance fields to u16 (Tvrtko) Bump mask fields to 64bits (Lionel) Don't return EPERM when dynamic sseu is disabled (Tvrtko) v9: Import context image into kernel context's ppgtt only when reconfiguring powergated slice/subslices (Chris) Use aliasing ppgtt when needed (Michel) Tvrtko Ursulin: v10: * Update for upstream changes. * Request submit needs a RPM reference. * Reject on !FULL_PPGTT for simplicity. * Pull out get/set param to helpers for readability and less indent. * Use i915_request_await_dma_fence in add_global_barrier to skip waits on the same timeline and avoid GEM_BUG_ON. * No need to explicitly assign a NULL pointer to engine in legacy mode. * No need to move gen8_make_rpcs up. * Factored out global barrier as prep patch. * Allow to only CAP_SYS_ADMIN if !Gen11. v11: * Remove engine vfunc in favour of local helper.
