Everyone knows them, except all the new folks joining from the ARM side haven't lived through all the pain of the past years and are entirely surprised when I raise this. Definitely time to document this. Last time this was a big discussion was about 6 years ago, when qcom tried to land a kernel driver without userspace. Dave Airlie made the rules really clear: http://airlied.livejournal.com/73115.html This write-up here is essentially what I've put into a presentation a while ago, which was also reviewed by Dave: http://blog.ffwll.ch/2015/05/gfx-kernel-upstreaming-requirements.html v2: Fix typos Eric&Rob spotted. v3: Nitpick from Jani.

The full name of PSR is Panel Self Refresh, panel device could refresh itself with the hardware framebuffer in panel, this would make lots of sense to save the power consumption.

The PSR driver have exported four symbols for specific device driver, and it's safe to call them in interrupt context: - rockchip_drm_psr_register() - rockchip_drm_psr_unregister() - rockchip_drm_psr_enable() - rockchip_drm_psr_disable() - rockchip_drm_psr_flush() Encoder driver should call the register/unregister interfaces to hook itself into common PSR driver, encoder have implement the 'psr_set' callback which use the set PSR state in hardware side. Crtc driver would call the enable/disable interfaces when vblank is enable/disable, after that the common PSR driver would call the encoder registered callback to set the PSR state. Fb driver would call the flush interface in 'fb->dirty' callback, this helper function would force all PSR enabled encoders to exit from PSR for 3 seconds. Signed-off-by:

VOP have integrated a hardware counter which indicate the exact display line that vop is scanning. And if we're interested in a specific line, we can set the line number to vop line_flag register, and then vop would generate a line_flag interrupt for it. For example eDP PSR function is interested in the vertical blanking period, then driver could set the line number to zero. This patch have exported a symbol that allow other driver to listen the line flag event with given timeout limit: - rockchip_drm_wait_line_flag() Signed-off-by:

Instead of just preparing the panel on bind, actually prepare/unprepare during modeset/disable. The panel must be prepared in order to read hpd status and edid, so we need to keep state around the prepares in order to ensure we don't accidentally turn the panel off at the wrong time. Reviewed-by:

There are two VOP in rk3399 chip, respectively VOP_BIG and VOP_LIT. most registers layout of this two vop is same, their framework are both VOP_FULL, the Major differences of this two is that: VOP_BIG max output resolution is 4096x2160. VOP_LIT max output resolution is 2560x1600 VOP_BIG support four windows. VOP_LIT only support two windows. RK3399 vop register layout is similar with rk3288, so some feature can reuse with rk3288.
