2020-05-28drm/amd/powerplay: remove the support of xgmi pstate on vega20 from swsmuKevin Wang3-14/+2
the vega20 asic uses legacy powerplay driver by default. 1. cleanup is_support_sw_smu_xgmi() function. (only use for vega20 xgmi pstate check) 2. by default, the vega20 set xgmi pstate by legacy powerplay routine.

[why] DP link layer CTS specs updated to change the test parameters in test 4.2.1.1. Before it requires source to delay 400us on aux no reply. With the specs updates Errata5, it requires source to delay 3.2ms (based on LTTPR aux timeout) This causes our test to fail after updating with the latest test equipment firmware. [how] the change is to allow LTTPR 3.2ms aux timeout delay by default. And only set to 400us if LTTPR is not present. Before this piece of logic is interwined with LTTPR support. Now we will default to 3.2ms aux timeout even if LTTPR support is not enabled by driver.

[Why] Due to packing of abm_config_table, memory addresses aren't aligned to 32 bit boundary dmcub prefers. Therefore when using pointers to this structure, it's possible that dmcub will automatically align the data read from that address, yielding incorrect values.

Across suspend/resume, we clear the entire GGTT and rebuild from scratch. In particular, we want to only preserve the global entries for use by the HW, and delay reinstating the local binds until required by the user. This means that we can evict any local binds in the global GTT, saving any time in preserving their state, as they will be rebound on demand.

2020-05-28drm/i915/gt: Prevent timeslicing into unpreemptable requestsChris Wilson3-2/+119
We have a I915_REQUEST_NOPREEMPT flag that we set when we must prevent the HW from preempting during the course of this request. We need to honour this flag and protect the HW even if we have a heartbeat request, or other maximum priority barrier, pending. As such, restrict the timeslicing check to avoid preempting into the topmost priority band, leaving the unpreemptable requests in blissful peace running uninterrupted on the HW. v2: Set the I915_PRIORITY_BARRIER to be less than I915_PRIORITY_UNPREEMPTABLE so that we never submit a request (heartbeat or barrier) that can legitimately preempt the current non-premptable request.

2020-05-27drm: Nuke mode->vrefreshVille Syrjälä66-394/+217
Get rid of mode->vrefresh and just calculate it on demand. Saves a bit of space and avoids the cached value getting out of sync with reality. Mostly done with cocci, with the following manual fixups: - Remove the now empty loop in drm_helper_probe_single_connector_modes() - Fix __MODE() macro in ch7006_mode.c - Fix DRM_MODE_ARG() macro in drm_modes.h - Remove leftover comment from samsung_s6d16d0_mode - Drop the TODO @@ @@ struct drm_display_mode { ... - int vrefresh; ... }; @@ identifier N; expression E; @@ struct drm_display_mode N = { - .vrefresh = E }; @@ identifier N; expression E; @@ struct drm_display_mode N[...] = { ..., { - .vrefresh = E } ,... }; @@ expression E; @@ { DRM_MODE(...), - .vrefresh = E, } @@ identifier M, R; @@ int drm_mode_vrefresh(const struct drm_display_mode *M) { ... - if (M->vrefresh > 0) - R = M->vrefresh; - else if (...) { ... } ... } @@ struct drm_display_mode *p; expression E; @@ ( - p->vrefresh = E; | - p->vrefresh + drm_mode_vrefresh(p) ) @@ struct drm_display_mode s; expression E; @@ ( - s.vrefresh = E; | - s.vrefresh + drm_mode_vrefresh(&s) ) @@ expression E; @@ - drm_mode_vrefresh(E) ? drm_mode_vrefresh(E) : drm_mode_vrefresh(E) + drm_mode_vrefresh(E) @find_substruct@ identifier X; identifier S; @@ struct X { ... struct drm_display_mode S; ... }; @@ identifier find_substruct.S; expression E; identifier I; @@ { .S = { - .vrefresh = E } } @@ identifier find_substruct.S; identifier find_substruct.X; expression E; identifier I; @@ struct X I[...] = { ..., .S = { - .vrefresh = E } ,... }; v2: Drop TODO v3: Rebase v4: Rebase Cc: Andrzej Hajda <a.hajda@samsung.com> Cc: Neil Armstrong <narmstrong@baylibre.com> Cc: Laurent Pinchart <Laurent.pinchart@ideasonboard.com> Cc: Jonas Karlman <jonas@kwiboo.se> Cc: Jernej Skrabec <jernej.skrabec@siol.net> Cc: Inki Dae <inki.dae@samsung.com> Cc: Joonyoung Shim <jy0922.shim@samsung.com> Cc: Seung-Woo Kim <sw0312.kim@samsung.com> Cc: Kyungmin Park <kyungmin.park@samsung.com> Cc: Linus Walleij <linus.walleij@linaro.org> Cc: CK Hu <ck.hu@mediatek.com> Cc: Philipp Zabel <p.zabel@pengutronix.de> Cc: Ben Skeggs <bskeggs@redhat.com> Cc: Thierry Reding <thierry.reding@gmail.com> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Jerry Han <hanxu5@huaqin.corp-partner.google.com> Cc: Icenowy Zheng <icenowy@aosc.io> Cc: Jagan Teki <jagan@amarulasolutions.com> Cc: Stefan Mavrodiev <stefan@olimex.com> Cc: Robert Chiras <robert.chiras@nxp.com> Cc: "Guido Günther" <agx@sigxcpu.org> Cc: Purism Kernel Team <kernel@puri.sm> Cc: Benjamin Gaignard <benjamin.gaignard@linaro.org> Cc: Vincent Abriou <vincent.abriou@st.com> Cc: VMware Graphics <linux-graphics-maintainer@vmware.com> Cc: Thomas Hellstrom <thellstrom@vmware.com> Cc: linux-amlogic@lists.infradead.org Cc: nouveau@lists.freedesktop.org Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Emil Velikov <emil.velikov@collabora.com> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200428171940.19552-4-ville.syrjala@linux.intel.com
2020-05-27drm/i915/gt: Clear LOCAL_BIND from shared GGTT on resumeChris Wilson1-2/+6
We only restore GLOBAL binds upon resume as we expect these to be pinned for use by HW, whereas the LOCAL binds can be recreated on demand once userspace is resumed. For the LOCAL bind to be recreated in the global GTT (for old systems without ppgtt), we need to clear its presence flag on deciding not to restore the mapping upon resume.

2020-05-27drm/i915/gt: Do not schedule normal requests immediately along virtualChris Wilson1-4/+21
When we push a virtual request onto the HW, we update the rq->engine to point to the physical engine. A request that is then submitted by the user that waits upon the virtual engine, but along the physical engine in use, will then see that it is due to be submitted to the same engine and take a shortcut (and be queued without waiting for the completion fence). However, the virtual request may be preempted (either by higher priority users, or by timeslicing) and removed from the physical engine to be migrated over to one of its siblings. The dependent normal request however is oblivious to the removal of the virtual request and remains queued to execute on HW, believing that once it reaches the head of its queue all of its predecessors will have completed executing! v2: Beware restriction of signal->execution_mask prior to submission.

2020-05-26drm/amdgpu: fix device attribute node create failed with multi gpuKevin Wang3-41/+58
the origin design will use varible of "attr->states" to save node supported states on current gpu device, but for multi gpu device, when probe second gpu device, the driver will check attribute node states from previous gpu device wthether to create attribute node. it will cause other gpu device create attribute node faild. 1. add member attr_list into amdgpu_device to link supported device attribute node. 2. add new structure "struct amdgpu_device_attr_entry{}" to track device attribute state. 3. drop member "states" from amdgpu_device_attr. v2: 1. move "attr_list" into amdgpu_pm and rename to "pm_attr_list". 2. refine create & remove device node functions parameter. fix: drm/amdgpu: optimize amdgpu device attribute code Signed-off-by: Kevin Wang <kevin1.wang@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2020-05-26drm/i915/display: Only query DP state of a DDI encoderChris Wilson1-0/+3
Avoid a NULL dereference for a mismatched encoder type, hit when probing state for all encoders. This is a band aid to prevent the OOPS as the right fix is "probably to swap the psr vs infoframes.enable checks, or outright disappear from this function" (Ville).
