The callback get_vblank_timestamp() is currently located in struct drm_driver, but really belongs into struct drm_crtc_funcs. Add an equivalent there. Driver will be converted in separate patches. The default implementation is drm_calc_vbltimestamp_from_scanoutpos(). The patch adds drm_crtc_vblank_helper_get_vblank_timestamp(), which is an implementation for the CRTC callback. v4: * more readable code for setting high_prec (Ville, Jani) v3: * use refactored timestamp calculation to minimize duplicated code * do more checks for crtc != NULL to support legacy drivers v2: * rename helper to drm_crtc_vblank_helper_get_vblank_timestamp() * replace drm_calc_vbltimestamp_from_scanoutpos() with drm_crtc_vblank_helper_get_vblank_timestamp() in docs Signed-off-by:

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:

VBLANK interrupts can be disabled immediately or with a delay, where the latter is the default. The former option can be selected by setting get_vblank_timestamp and enabling vblank_disable_immediate in struct drm_device.

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.

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

At least one panel hooked up to the bridge (AUO B116XAK01) only supports 1 lane of DP. Let's read this information and stop hardcoding 4 DP lanes. Signed-off-by:

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. This is all in prep for fixing some of the above. Signed-off-by:

When we iterate over ti_sn_bridge_dp_rate_lut, there's no reason to start at index 0 which always contains the value 0. 0 is not a valid link rate. This change should have no real effect but is a small cleanup. Signed-off-by:

These two things were in one function. Split into two. This looks like it's duplicating some code, but don't worry. This is is just in preparation for future changes. This is intended to have zero functional change and will just make future patches easier to understand. Signed-off-by:

This patch reworks the whole delayed deletion of BOs which aren't idle. Instead of having two counters for the BO structure we resurrect the BO when we find that a deleted BO is not idle yet. This has many advantages, especially that we don't need to increment/decrement the BOs reference counter any more when it moves on the LRUs. v2: remove duplicate ttm_tt_destroy, fix holde lock for LRU move Signed-off-by:
