Enable the panel before adjusting eDP link params, make sure the panel is idle after powering it on before proceeding with other activity, delay backlight enable to avoid visible flicker. Also avoid using VDD per hw team recommendation; it can conflict with the builtin panel power sequencing logic and lead to panel power sequencing failures. Signed-off-by:

FDI training needs to done and idle for PCH eDP and before we turn the pipes on, and various eDP checks need to account for PCH attached eDP. Signed-off-by:

Since we set the output type of PCH attached eDP panels to INTEL_OUTPUT_eDP this function would never return true when it should. It's been replaced by working functions. Signed-off-by:

If is_edp is true, is_pch_edp will always be true. So limit the calls to the latter function to places where the distinction actually matters. Signed-off-by:

Currently, if a batch buffer refers to an object with a pending flip, then we sleep until that pending flip is completed (unpinned and signalled). This is so that a flip can be queued and the user can continue rendering to the backbuffer oblivious to whether the buffer is still pinned as the scan out. (The kernel arbitrating at the last moment to stall the batch and wait until the buffer is unpinned and replaced as the front buffer.) As we only have a queue depth of 1, we can simply wait for the current pending flip to complete and continue rendering. We can achieve this with a single WAIT_FOR_EVENT command inserted into the ring buffer prior to executing the batch, *without* stalling the client. Signed-off-by: -

Francisco Jerez advises that pre-nv20 cards would hang if we entered kdb with accel on and IRQs disabled, so we now disable accel before entering kdb and re-enable it on the way back out. Reported-by:

When changing VTs non-atomically the kernel works in conjunction with the Xserver in user space and receives the LUT information from the Xserver via a system call. When changing modes atomically for kdb, this information must be saved and restored without disturbing user space as if nothing ever happened. Signed-off-by:

Jason Wessel authored
Some devices such as the radeon chips receive information from user space which needs to be saved when executing an atomic mode set operation, else the user space would have to be queried again for the information. This patch extends the mode_set_base_atomic() call to pass an argument to indicate if this is an entry or an exit from an atomic kernel mode set change. Individual drm drivers can properly save and restore state accordingly. Signed-off-by:

This patch implements blit support for bo moves using the 3D engine. It uses the same method as r6xx/r7xx: - store the base state in an IB - emit variable state and vertex buffers to do the blit This allows the hw to move bos using the 3D engine and allows full use of vram beyond the pci aperture size.

radeon_pm_in_vbl() didn't report in vblank status accurately. Make it a wrapper around radeon_get_crtc_scanoutpos() which corrects for biases, so it reports accurately. radeon_pm_in_vbl() will only report in_vbl if all active crtc's are currently inside vblank. agd5f: use rdev->num_crtc rather than hardcoding the crtc count Signed-off-by:

radeon_get_crtc_scanoutpos() returns the current horizontal and vertical scanout position of a crtc. It also reports if the display scanout is currently inside the vblank area. hpos reports current horizontal pixel scanout position. vpos reports the current scanned out line as a value >= 0 in active scanout. If the scanout is inside vblank area, it reports a negative value, the number of scanlines until end of vblank aka start of active scanout, e.g., -3 == "At most 3 scanlines until end of vblank". This code is derived from radeon_pm_in_vbl(), tested on R500 and R600. Signed-off-by:

This patch reworks spread spectrum handling to enable it properly on lvds and DP/eDP links. It also fixes several bugs in the old spread spectrum code. - Use the ss recommended reference divider if available when calculating the pll - Use the proper ss command tables on pre-DCE3 asics - Avoid reading past the end of the ss info tables - Enable ss on evergreen asics (lvds, dp, tmds) - Enable ss on DP/eDP links Signed-off-by:

The recent changes to the old algo (prefer high post div) coupled with the range and precision limitations of using fixed point with the new algo make the new algo less useful. So drop the new algo. This should work as well or better than the old new/old combinations and simplifies the code a lot. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=30218 among others. Signed-off-by:

This allows for a more exact fitting on the physical display. The new properties default to zero which corresponds to the previous underscan border width[height] formula: (display_width[display_width] >> 5) + 16. Example to set a horizontal border width of 30 and a vertikal border height of 22: xrandr --output HDMI-0 --set underscan on --set "underscan hborder" 30 --set "underscan vborder" 22 Signed-off-by:

On r6xx+ a newer fence mechanism was implemented to replace the old wait_until plus scratch regs setup. A single EOP event will flush the destination caches, write a fence value, and generate an interrupt. This is the recommended fence mechanism on r6xx+ asics. This requires my previous writeback patch. v2: fix typo that enabled event fence checking on all asics rather than just r6xx+. v3: properly enable EOP interrupts Should fix: https://bugs.freedesktop.org/show_bug.cgi?id=29972Signed-off-by:

When writeback is enabled, the GPU shadows writes to certain registers into a buffer in memory. The driver can then read the values from the shadow rather than reading back from the register across the bus. Writeback can be disabled by setting the no_wb module param to 1. On r6xx/r7xx/evergreen, the following registers are shadowed: - CP scratch registers - CP read pointer - IH write pointer On r1xx-rr5xx, the following registers are shadowed: - CP scratch registers - CP read pointer v2: - Combine wb patches for r6xx-evergreen and r1xx-r5xx - Writeback is disabled on AGP boards since it tends to be unreliable on AGP using the gart. - Check radeon_wb_init return values properly.
