* drm/amdgpu: Avoid overflows/divide-by-zero in latency_watermark calculations.Mario Kleiner2017-05-25
| | | | | | | | | | | | | | | | | | | | | | | commit e190ed1ea7458e446230de4113cc5d53b8dc4ec8 upstream. At dot clocks > approx. 250 Mhz, some of these calcs will overflow and cause miscalculation of latency watermarks, and for some overflows also divide-by-zero driver crash ("divide error: 0000 [#1] PREEMPT SMP" in "dce_v10_0_latency_watermark+0x12d/0x190"). This zero-divide happened, e.g., on AMD Tonga Pro under DCE-10, on a Displayport panel when trying to set a video mode of 2560x1440 at 165 Hz vrefresh with a dot clock of 635.540 Mhz. Refine calculations to avoid the overflows. Tested for DCE-10 with R9 380 Tonga + ASUS ROG PG279 panel.

* drm/amdgpu: Make display watermark calculations more accurateMario Kleiner2017-05-25
| | | | | | | | | | | | | | | | | commit d63c277dc672e0c568481af043359420fa9d4736 upstream. Avoid big roundoff errors in scanline/hactive durations for high pixel clocks, especially for >= 500 Mhz, and thereby program more accurate display fifo watermarks. Implemented here for DCE 6,8,10,11. Successfully tested on DCE 10 with AMD R9 380 Tonga.

* drm/amdgpu: Store CRTC relative amdgpu_crtc->cursor_x/y valuesMichel Dänzer2017-01-09
| | | | | | | | | | | | | | | commit 8e57ec613df7d6bfa8ffe7512290c5415ebb8657 upstream. We were storing viewport relative coordinates. However, crtc_cursor_set2 and cursor_reset pass amdgpu_crtc->cursor_x/y as the x/y parameters of cursor_move_locked, which would break if the CRTC isn't located at (0, 0).

| | | | | | | | | | | | We need this for more than just DCE. Move it out of the DCE modules and into the device code.

* drm/amdgpu: Fixup hw vblank counter/ts for new drm_update_vblank_count() (v3)Alex Deucher2015-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 4dfd6486 "drm: Use vblank timestamps to guesstimate how many vblanks were missed" introduced in Linux 4.4-rc1 makes the drm core more fragile to drivers which don't update hw vblank counters and vblank timestamps in sync with firing of the vblank irq and essentially at leading edge of vblank. This exposed a problem with radeon-kms/amdgpu-kms which do not satisfy above requirements: The vblank irq fires a few scanlines before start of vblank, but programmed pageflips complete at start of vblank and vblank timestamps update at start of vblank, whereas the hw vblank counter increments only later, at start of vsync. This leads to problems like off by one errors for vblank counter updates, vblank counters apparently going backwards or vblank timestamps apparently having time going backwards. The net result is stuttering of graphics in games, or little hangs, as well as total failure of timing sensitive applications. See bug #93147 for an example of the regression on Linux 4.4-rc: https://bugs.freedesktop.org/show_bug.cgi?id=93147 This patch tries to align all above events better from the viewpoint of the drm core / of external callers to fix the problem: 1. The apparent start of vblank is shifted a few scanlines earlier, so the vblank irq now always happens after start of this extended vblank interval and thereby drm_update_vblank_count() always samples the updated vblank count and timestamp of the new vblank interval. To achieve this, the reporting of scanout positions by radeon_get_crtc_scanoutpos() now operates as if the vblank starts radeon_crtc->lb_vblank_lead_lines before the real start of the hw vblank interval. This means that the vblank timestamps which are based on these scanout positions will now update at this earlier start of vblank. 2. The driver->get_vblank_counter() function will bump the returned vblank count as read from the hw by +1 if the query happens after the shifted earlier start of the vblank, but before the real hw increment at start of vsync, so the counter appears to increment at start of vblank in sync with the timestamp update. 3. Calls from vblank irq-context and regular non-irq calls are now treated identical, always simulating the shifted vblank start, to avoid inconsistent results for queries happening from vblank irq vs. happening from drm_vblank_enable() or vblank_disable_fn(). 4. The radeon_flip_work_func will delay mmio programming a pageflip until the start of the real vblank iff it happens to execute inside the shifted earlier start of the vblank, so pageflips now also appear to execute at start of the shifted vblank, in sync with vblank counter and timestamp updates. This to avoid some races between updates of vblank count and timestamps that are used for swap scheduling and pageflip execution which could cause pageflips to execute before the scheduled target vblank. The lb_vblank_lead_lines "fudge" value is calculated as the size of the display controllers line buffer in scanlines for the given video mode: Vblank irq's are triggered by the line buffer logic when the line buffer refill for a video frame ends, ie. when the line buffer source read position enters the hw vblank. This means that a vblank irq could fire at most as many scanlines before the current reported scanout position of the crtc timing generator as the number of scanlines the line buffer can maximally hold for a given video mode. This patch has been successfully tested on a RV730 card with DCE-3 display engine and on a evergreen card with DCE-4 display engine, in single-display and dual-display configuration, with different video modes. A similar patch is needed for amdgpu-kms to fix the same problem. Limitations: - Maybe replace the udelay() in the flip_work_func() by a suitable usleep_range() for a bit better efficiency? Will try that. - Line buffer sizes in pixels are hard-coded on < DCE-4 to a value i just guessed to be high enough to work ok, lacking info on the true sizes atm.

In amdgpu_flip_work_func, replace the busy waiting udelay(5) with event lock held by a more performance and energy efficient usleep_range() until at least predicted true start of hw vblank, with some slack for scheduler happiness. Release the event lock during waits to not delay other outputs in doing their stuff, as the waiting can last up to 200 usecs in some cases. Also small fix to code comment and formatting in that function. (v2) Signed-off-by: Mario Kleiner <mario.kleiner.de@gmail.com> (v3) Fix crash in crtc disabled case
