2018-02-19drm/amdgpu: drop the drm irq pre/post/un install callbacksAlex Deucher1-50/+2
The preinstall callback didn't do anything because not all of the IPs were initialized when it was called. Move the postinstall setup into sequence in the driver. The uninstall callback disabled all interrupt source, but it got called too late in the driver sequence and caused problems with IPs who already freed the relevant data structures. Move the call into the right place in the driver sequence.

2017-07-14drm/amdgpu: Allow vblank_disable_immediate.Mario Kleiner1-0/+4
With instantaneous high precision vblank timestamping that updates at leading edge of vblank, a cooked hw vblank counter which increments at leading edge of vblank, and reliable page flip execution and completion at leading edge of vblank, we should meet the requirements for fast/immediate vblank irq disable/enable. Testing on Linux-4.12-rc5 + drm-next on a Radeon R9 380 Tonga Pro (DCE 10) with timing measurement equipment indicates this works fine, so allow immediate vblank disable for power saving. For debugging in case of unexpected trouble, booting with kernel cmdline option drm.vblankoffdelay=0 (or echo 0 > /sys/module/drm/parameters/vblankoffdelay) would keep vblank irqs permanently on to approximate old behavior.

Both drivers shut down all crtc beforehand already, which will shut up any pending vblank (the only thing vblank_cleanup really does is disable the disable timer).

This was added in commit 0a3e67a4caac273a3bfc4ced3da364830b1ab241 Author: Jesse Barnes <[email protected]> Date: Tue Sep 30 12:14:26 2008 -0700 drm: Rework vblank-wait handling to allow interrupt reduction. to stay backwards-compatible with old UMS code that didn't even tell the kernel when it did a modeset, so that the kernel could save/restore vblank counters. At worst this means vblanks will be somewhat funky on a setup that very likely no one still runs. So let's just nuke it. Plan B would be to set it unconditionally in drm_vblank_init for kms drivers, instead of in each driver separately. So if this patch breaks anything please only restore the hunks in drmP.h and drm_irq.c, plus add a check for DRIVER_MODESET in drm_vblank_init. Stumbled over this in a discussion on irc with Chris.
