2019-03-09drm/v3d: Add support for V3D v4.2.Eric Anholt4-17/+63
No compatible string for it yet, just the version-dependent changes. They've now tied the hub and the core interrupt lines into a single interrupt line coming out of the block. It also turns out I made a mistake in modeling the V3D v3.3 and v4.1 bridge as a part of V3D itself -- the bridge is going away in favor of an external reset controller in a larger HW module. v2: Use consistent checks for whether we're on 4.2, and fix a leak in an error path. v3: Use more general means of determining if the current 4.2 changes are in place, as apparently other platforms may switch back (noted by Dave). Update the binding doc. v4: Improve error handling for IRQ init.

2019-03-07drm/sun4i: rgb: Change the pixel clock validation checkMaxime Ripard1-2/+35
The current code, since commit bb43d40d7c83 ("drm/sun4i: rgb: Validate the clock rate"), perform some validation on the pixel clock to filter out the EDID modes provided by monitors (through bridges) that we wouldn't be able to reach. For the usual modes, we're able to generate a perfect clock rate, so a strict check was enough. However, this had the side effect of preventing displays that would work otherwise to operate properly, since we would pretty much never be able to generate an exact rate for those displays, even though we would fall within that panel tolerance. This was also shown to happen for unusual modes exposed through EDIDs, for example on eDP panels. We can work around this by simplifying a bit the problem: no panels we've encountered so far actually needed that check. All of them are tied to a particular board when it is produced, and made to work with the Allwinner BSP. That pretty much guarantees that we never have a pixel clock out of reach. On the other hand, the EDIDs modes that needed to be validated have always been exposed through bridges. Let's just use that metric to instead of validating all modes, only validate modes when we have a bridge attached. It should be good enough for now, while we still have room for improvements or refinements using the display_timings structure for example for panels. We also add a tolerance for EDID-based modes instead of doing a strict check. This tolerance is of 0.5% which is the one advertised in the VESA DVT and CVT specs. If that needed to be extended in the future, we can add a custom module parameter to relax it a bit.

2019-03-07drm/vc4: Use 16bpp by default for the fbdev bufferMaxime Ripard1-1/+1
The preferred bpp for the fbdev emulation buffer has been 32 so far, which means that by default we will allocate an 8MB buffer with a 1920x1080 resolution. Worse this memory will be allocated from the CMA pool, and will never be freed even if we don't use the fbdev emulation. Therefore, reducing it is a big deal, and switching to 16bpp by default will gain us around 4MB at 1920x1080, while keeping decent color depth. And users still have the option to switch to 32bpp using the kernel command line.

2019-03-06drm/vc4: Add a debugfs entry to disable/enable the load trackerPaul Kocialkowski3-0/+21
In order to test whether the load tracker is working as expected, we need the ability to compare the commit result with the underrun indication. With the load tracker always enabled, commits that are expected to trigger an underrun are always rejected, so userspace cannot get the actual underrun indication from the hardware. Add a debugfs entry to disable/enable the load tracker, so that a DRM commit expected to trigger an underrun can go through with the load tracker disabled. The underrun indication is then available to userspace and can be checked against the commit result with the load tracker enabled.

2019-03-06drm/vc4: Add a load tracker to prevent HVS underflow errorsBoris Brezillon4-1/+171
The HVS block is supposed to fill the pixelvalve FIFOs fast enough to meet the requested framerate. The problem is, the HVS and memory bus bandwidths are limited, and if we don't take these limitations into account we might end up with HVS underflow errors. This patch is trying to model the per-plane HVS and memory bus bandwidth consumption and take a decision at atomic_check() time whether the estimated load will fit in the HVS and membus budget. Note that we take an extra margin on the memory bus consumption to let the system run smoothly when other blocks are doing heavy use of the memory bus. Same goes for the HVS limit, except the margin is smaller in this case, since the HVS is not used by external components.

2019-03-05drm/dsc: Split DSC PPS and SDP header initialisationsDavid Francis2-61/+60
The DP 1.4 spec defines the SDP header and SDP contents for a Picture Parameter Set (PPS) that must be sent in advance of DSC transmission to define the encoding characteristics. This was done in one struct, drm_dsc_pps_infoframe, which conatined the SDP header and PPS. Because the PPS is a property of DSC over any connector, not just DP, and because drm drivers may have their own SDP structs they wish to use, make the functions that initialise SDP and PPS headers take the components they operate on, not drm_dsc_pps_infoframe, Signed-off-by: David Francis <David.Francis@amd.com> Reviewed-by: Manasi Navare <manasi.d.navare@intel.com> Signed-off-by: Harry Wentland <harry.wentland@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190221202001.28430-4-David.Francis@amd.com

2019-03-05drm/amd/display: Use vrr friendly pageflip throttling in DC.Mario Kleiner1-1/+27
In VRR mode, keep track of the vblank count of the last completed pageflip in amdgpu_crtc->last_flip_vblank, as recorded in the pageflip completion handler after each completed flip. Use that count to prevent mmio programming a new pageflip within the same vblank in which the last pageflip completed, iow. to throttle pageflips to at most one flip per video frame, while at the same time allowing to request a flip not only before start of vblank, but also anywhere within vblank. The old logic did the same, and made sense for regular fixed refresh rate flipping, but in vrr mode it prevents requesting a flip anywhere inside the possibly huge vblank, thereby reducing framerate in vrr mode instead of improving it, by delaying a slightly delayed flip requests up to a maximum vblank duration + 1 scanout duration. This would limit VRR usefulness to only help applications with a very high GPU demand, which can submit the flip request before start of vblank, but then have to wait long for fences to complete. With this method a flip can be both requested and - after fences have completed - executed, ie. it doesn't matter if the request (amdgpu_dm_do_flip()) gets delayed until deep into the extended vblank due to cpu execution delays. This also allows clients which want to regulate framerate within the vrr range a much more fine-grained control of flip timing, a feature that might be useful for video playback, and is very useful for neuroscience/vision research applications. In regular non-VRR mode, retain the old flip submission behavior. This to keep flip scheduling for fullscreen X11/GLX OpenGL clients intact, if they use the GLX_OML_sync_control extensions glXSwapBufferMscOML(, ..., target_msc,...) function with a specific target_msc target vblank count. glXSwapBuffersMscOML() or DRI3/Present PresentPixmap() will not flip at the proper target_msc for a non-zero target_msc if VRR mode is active with this patch. They'd often flip one frame too early. However, this limitation should not matter much in VRR mode, as scheduling based on vblank counts is pretty futile/unusable under variable refresh duration anyway, so no real extra harm is done.

2019-03-04drm/tinydrm: Use drm_dev_enter/exit()Noralf Trønnes8-32/+139
This protects device resources from use after device removal. There are 3 ways for driver-device unbinding to happen: - The driver module is unloaded causing the driver to be unregistered. This can't happen as long as there are open file handles because a reference is taken on the module. - The device is removed (Device Tree overlay unloading). This can happen at any time. - The driver sysfs unbind file can be used to unbind the driver from the device. This can happen any time. v2: Since drm_atomic_helper_shutdown() has to be called after drm_dev_unplug() we don't want do block ->disable after unplug.

2019-03-02geneve: correctly handle ipv6.disable module parameterJiri Benc1-3/+8
When IPv6 is compiled but disabled at runtime, geneve_sock_add returns -EAFNOSUPPORT. For metadata based tunnels, this causes failure of the whole operation of bringing up the tunnel. Ignore failure of IPv6 socket creation for metadata based tunnels caused by IPv6 not being available. This is the same fix as what commit d074bf960044 ("vxlan: correctly handle ipv6.disable module parameter") is doing for vxlan. Note there's also commit c0a47e44c098 ("geneve: should not call rt6_lookup() when ipv6 was disabled") which fixes a similar issue but for regular tunnels, while this patch is needed for metadata based tunnels.

2019-03-02net: dsa: mv88e6xxx: prevent interrupt storm caused by mv88e6390x_port_set_cmodeHeiner Kallweit3-0/+15
When debugging another issue I faced an interrupt storm in this driver (88E6390, port 9 in SGMII mode), consisting of alternating link-up / link-down interrupts. Analysis showed that the driver wanted to set a cmode that was set already. But so far mv88e6390x_port_set_cmode() doesn't check this and powers down SERDES, what causes the link to break, and eventually results in the described interrupt storm. Fix this by checking whether the cmode actually changes. We want that the very first call to mv88e6390x_port_set_cmode() always configures the registers, therefore initialize port.cmode with a value that is different from any supported cmode value. We have to take care that we only init the ports cmode once chip->info->num_ports is set. v2: - add small helper and init the number of actual ports only Fixes: 364e9d7776a3 ("net: dsa: mv88e6xxx: Power on/off SERDES on cmode change") Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S.
