2020-02-13drm: Add get_scanout_position() to struct drm_crtc_helper_funcsThomas Zimmermann4-23/+157
The new callback get_scanout_position() reads the current location of the scanout process. The operation is currently located in struct drm_driver, but really belongs to the CRTC. Drivers will be converted in separate patches. To help with the conversion, the timestamp calculation has been moved from drm_calc_vbltimestamp_from_scanoutpos() to drm_crtc_vblank_helper_get_vblank_timestamp_internal(). The helper function supports the new and old interface of get_scanout_position(). drm_calc_vbltimestamp_from_scanoutpos() remains as a wrapper around the new function. Callback functions return the scanout position from the CRTC. The legacy version of the interface receives the device and pipe index, the modern version receives a pointer to the CRTC. We keep the legacy version until all drivers have been converted. v4: * 80-character line fixes v3: * refactor drm_calc_vbltimestamp_from_scanoutpos() to minimize code duplication * define types for get_scanout_position() callbacks v2: * fix logical op in drm_calc_vbltimestamp_from_scanoutpos() Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Tested-by: Yannick Fertré <yannick.fertre@st.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200123135943.24140-3-tzimmermann@suse.de

2020-02-13drm/qxl: replace zero-length array with flexible-array memberGustavo A. R. Silva1-1/+1
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertenly introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

Based on work by Bjorn Andersson <bjorn.andersson@linaro.org>, Jeffrey Hugo <jeffrey.l.hugo@gmail.com>, and Rob Clark <robdclark@chromium.org>. Let's read the SUPPORTED_LINK_RATES and/or MAX_LINK_RATE (depending on the eDP version of the sink) to figure out what eDP rates are supported and pick the ideal one. NOTE: I have only personally tested this code on eDP panels that are 1.3 or older. Code reading SUPPORTED_LINK_RATES for DP 1.4+ was tested by hacking the code to pretend that a table was there.

2020-02-13drm/bridge: ti-sn65dsi86: Train at faster rates if slower ones failDouglas Anderson1-11/+60
If we fail training at a lower DP link rate let's now keep trying until we run out of rates to try. Basically the algorithm here is to start at the link rate that is the theoretical minimum and then slowly bump up until we run out of rates or hit the max rate of the sink. We query the sink using a DPCD read. This is, in fact, important in practice. Specifically at least one panel hooked up to the bridge (AUO B116XAK01) had a theoretical min rate more than 1.62 GHz (if run at 24 bpp) and fails to train at the next rate (2.16 GHz). It would train at 2.7 GHz, though.

We'll re-organize the ti_sn_bridge_enable() function a bit to group together all the parts relating to link training and split them into a sub-function. This is not intended to have any functional change and is in preparation for trying link training several times at different rates. One small side effect here is that if link training fails we'll now leave the DP PLL disabled, but that seems like a sane thing to do.

2020-02-13drm/bridge: ti-sn65dsi86: Use 18-bit DP if we canDouglas Anderson1-9/+18
The current bridge driver always forced us to use 24 bits per pixel over the DP link. This is a waste if you are hooked up to a panel that only supports 6 bits per color or fewer, since in that case you can run at 18 bits per pixel and thus end up at a lower DP clock rate. Let's support this. While at it, let's clean up the math in the function to avoid rounding errors (and round in the correct direction when we have to round). Numbers are sufficiently small (because mode->clock is in kHz) that we don't need to worry about integer overflow.

The driver used to say that the value to program into bridge register 0x93 was dp_lanes - 1. Looking at the datasheet for the bridge, this is wrong. The data sheet says: * 1 = 1 lane * 2 = 2 lanes * 3 = 4 lanes A more proper way to express this encoding is min(dp_lanes, 3). At the moment this change has zero effect because we've hardcoded the number of DP lanes to 4. ...and (4 - 1) == min(4, 3). How fortunate! ...but soon we'll stop hardcoding the number of lanes.

The ti-sn65dsi86 is a bridge from MIPI to DP and thus has two links: the MIPI link and the DP link. The two links do not need to have the same format or number of lanes. Stop using MIPI variables when talking about the DP link. This has zero functional change because: * currently we are hardcoding the MIPI link as unpacked RGB888 which requires 24 bits and currently we are not changing the DP link rate from the bridge's default of 8 bits per pixel. * currently we are hardcoding both the MIPI and DP as being 4 lanes.

2020-02-12ice: fix and consolidate logging of NVM/firmware version informationBruce Allan4-28/+13
Logging the firmware/NVM information during driver load is redundant since that information is also available via ethtool. Move the functionality found in ice_nvm_version_str() directly into ice_get_drvinfo() and remove calling the former and logging that info during driver probe. This also gets rid of a bug in ice_nvm_version_str() where it returns a pointer to a buffer which is free'ed when that function exits.

Currently we compare the value we are about to write to the Rx tail register with the previous value of next_to_use. The problem with this is we only write tail on 8 descriptor boundaries, but next_to_use is updated whenever we clean Rx descriptors. Fix this by comparing the value we are about to write to tail with the previously written tail value. This will prevent duplicate Rx tail bumps.

2020-02-12ice: Fix switch between FW and SW LLDPDave Ertman1-5/+5
When switching between FW and SW LLDP mode, the number of configured TLV apps in the driver's DCB configuration is getting out of synch with what lldpad thinks is configured. This is causing a problem when shutting down lldpad. The cleanup is trying to delete TLV apps that are not defined in the kernel. Since the driver is keeping an accurate account of the apps defined, use the drivers number of apps to determine if there is an app to delete. If the number of apps is <= 1, then do not attempt to delete.

2020-02-12ice: Fix DCB rebuild after resetDave Ertman2-53/+36
The function ice_dcb_rebuild had some logic flaws in it, and also didn't differentiate between FW and SW modes needs. For FW flow, the willing setting was being forced to OFF and left that way. Unwilling in DCB FW mode is not a supported model. Leave the config alone and use the return value from the set command to determine if setting the config was successful. The SW DCB flow does not need to need to register for MIB change events (as they are not used in SW mode). Use !is_sw_lldp checks to only perform FW specific task while in FW mode. Also adding a reapplication of the current DCB config after a link event. Some NVMs are not maintaining their DCB configs across link events.
