drm/radeon: Fixup hw vblank counter/ts for new drm_update_vblank_count() (v2) 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: - 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.

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. Retested on DCE-3 and DCE-4 to verify it still works nicely. (v2) Signed-off-by: Mario Kleiner <mario.kleiner.de@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

drm/radeon: add 2-level VM pagetables support v9 PDE/PTE update code uses CP ring for memory writes. All page table entries are preallocated for now in alloc_pt(). It is made as whole because it's hard to divide it to several patches that compile and doesn't break anything being applied separately. Tested on cayman card. v2: rebased on top of "refactor set_page chipset interface v3", code cleanups v3: switched offsets calc macros to inline funcs where possible, remove pd_addr from radeon_vm, switched RADEON_BLOCK_SIZE define, to 9 (and PTE_COUNT to 1 << BLOCK_SIZE) v4 (ck): move "incr" documentation to previous patch, cleanup and document RADEON_VM_* constants, change commit message to our usual format, simplify patch allot by removing everything current not necessary, disable SI workaround. v5: (agd5f): Fix typo in tables_size calculation in radeon_vm_alloc_pt(). Second line should have been '+=' rather than '='. v6: fix npdes calculation. In scenario when pfns to be mapped overlap two PDE spans: +-----------+-------------+ | PDE span | PDE span | +-----------+----+--------+ | | +---------+ | pfns | +---------+ the following npdes calculation gives incorrect result: npdes = (nptes >> RADEON_VM_BLOCK_SIZE) + 1; For the case above picture it should give npdes = 2, but gives one. This patch corrects it by rounding last pfn up to 512 border, first - down to 512 border and then subtracting and dividing by 512. v7: Make npde calculation clearer, fix ndw calculation. v8: (agd5f): reserve enough for 2 full VM PTs, add some additional comments. v9: fix typo in npde calculation Signed-off-by: Dmitry Cherkasov <Dmitrii.Cherkasov@amd.com> Signed-off-by: Christian König <deathsimple@vodafone.de> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

drm/radeon: Handle irqs only based on irq ring, not irq status regs. Trying to resolve issues with missed vblanks and impossible values inside delivered kms pageflip completion events showed that radeon's irq handling sometimes doesn't handle valid irqs, but silently skips them. This was observed for vblank interrupts. Although those irqs have corresponding events queued in the gpu's irq ring at time of interrupt, and therefore the corresponding handling code gets triggered by these events, the handling code sometimes silently skipped processing the irq. The reason for those skips is that the handling code double-checks for each irq event if the corresponding irq status bits in the irq status registers are set. Sometimes those bits are not set at time of check for valid irqs, maybe due to some hardware race on some setups? The problem only seems to happen on some machine + card combos sometimes, e.g., never happened during my testing of different PC cards of the DCE-2/3/4 generation a year ago, but happens consistently now on two different Apple Mac cards (RV730, DCE-3, Apple iMac and Evergreen JUNIPER, DCE-4 in a Apple MacPro). It also doesn't happen at each interrupt but only occassionally every couple of hundred or thousand vblank interrupts. This results in XOrg warning messages like "[ 7084.472] (WW) RADEON(0): radeon_dri2_flip_event_handler: Pageflip completion event has impossible msc 420120 < target_msc 420121" as well as skipped frames and problems for applications that use kms pageflip events or vblank events, e.g., users of DRI2 and DRI3/Present, Waylands Weston compositor, etc. See also https://bugs.freedesktop.org/show_bug.cgi?id=85203 After some talking to Alex and Michel, we decided to fix this by turning the double-check for asserted irq status bits into a warning. Whenever a irq event is queued in the IH ring, always execute the corresponding interrupt handler. Still check the irq status bits, but only to log a DRM_DEBUG message on a mismatch. This fixed the problems reliably on both previously failing cards, RV-730 dual-head tested on both crtcs (pipes D1 and D2) and a triple-output Juniper HD-5770 card tested on all three available crtcs (D1/D2/D3). The r600 and evergreen irq handling is therefore tested, but the cik an si handling is only compile tested due to lack of hw.

drm/radeon: Handle irqs only based on irq ring, not irq status regs. Trying to resolve issues with missed vblanks and impossible values inside delivered kms pageflip completion events showed that radeon's irq handling sometimes doesn't handle valid irqs, but silently skips them. This was observed for vblank interrupts. Although those irqs have corresponding events queued in the gpu's irq ring at time of interrupt, and therefore the corresponding handling code gets triggered by these events, the handling code sometimes silently skipped processing the irq. The reason for those skips is that the handling code double-checks for each irq event if the corresponding irq status bits in the irq status registers are set. Sometimes those bits are not set at time of check for valid irqs, maybe due to some hardware race on some setups? The problem only seems to happen on some machine + card combos sometimes, e.g., never happened during my testing of different PC cards of the DCE-2/3/4 generation a year ago, but happens consistently now on two different Apple Mac cards (RV730, DCE-3, Apple iMac and Evergreen JUNIPER, DCE-4 in a Apple MacPro). It also doesn't happen at each interrupt but only occassionally every couple of hundred or thousand vblank interrupts. This results in XOrg warning messages like "[ 7084.472] (WW) RADEON(0): radeon_dri2_flip_event_handler: Pageflip completion event has impossible msc 420120 < target_msc 420121" as well as skipped frames and problems for applications that use kms pageflip events or vblank events, e.g., users of DRI2 and DRI3/Present, Waylands Weston compositor, etc. See also https://bugs.freedesktop.org/show_bug.cgi?id=85203 After some talking to Alex and Michel, we decided to fix this by turning the double-check for asserted irq status bits into a warning. Whenever a irq event is queued in the IH ring, always execute the corresponding interrupt handler. Still check the irq status bits, but only to log a DRM_DEBUG message on a mismatch. This fixed the problems reliably on both previously failing cards, RV-730 dual-head tested on both crtcs (pipes D1 and D2) and a triple-output Juniper HD-5770 card tested on all three available crtcs (D1/D2/D3). The r600 and evergreen irq handling is therefore tested, but the cik an si handling is only compile tested due to lack of hw.

drm/radeon: Handle irqs only based on irq ring, not irq status regs. Trying to resolve issues with missed vblanks and impossible values inside delivered kms pageflip completion events showed that radeon's irq handling sometimes doesn't handle valid irqs, but silently skips them. This was observed for vblank interrupts. Although those irqs have corresponding events queued in the gpu's irq ring at time of interrupt, and therefore the corresponding handling code gets triggered by these events, the handling code sometimes silently skipped processing the irq. The reason for those skips is that the handling code double-checks for each irq event if the corresponding irq status bits in the irq status registers are set. Sometimes those bits are not set at time of check for valid irqs, maybe due to some hardware race on some setups? The problem only seems to happen on some machine + card combos sometimes, e.g., never happened during my testing of different PC cards of the DCE-2/3/4 generation a year ago, but happens consistently now on two different Apple Mac cards (RV730, DCE-3, Apple iMac and Evergreen JUNIPER, DCE-4 in a Apple MacPro). It also doesn't happen at each interrupt but only occassionally every couple of hundred or thousand vblank interrupts. This results in XOrg warning messages like "[ 7084.472] (WW) RADEON(0): radeon_dri2_flip_event_handler: Pageflip completion event has impossible msc 420120 < target_msc 420121" as well as skipped frames and problems for applications that use kms pageflip events or vblank events, e.g., users of DRI2 and DRI3/Present, Waylands Weston compositor, etc. See also https://bugs.freedesktop.org/show_bug.cgi?id=85203 After some talking to Alex and Michel, we decided to fix this by turning the double-check for asserted irq status bits into a warning.

drm/radeon: Handle irqs only based on irq ring, not irq status regs. Trying to resolve issues with missed vblanks and impossible values inside delivered kms pageflip completion events showed that radeon's irq handling sometimes doesn't handle valid irqs, but silently skips them. This was observed for vblank interrupts. Although those irqs have corresponding events queued in the gpu's irq ring at time of interrupt, and therefore the corresponding handling code gets triggered by these events, the handling code sometimes silently skipped processing the irq. The reason for those skips is that the handling code double-checks for each irq event if the corresponding irq status bits in the irq status registers are set. Sometimes those bits are not set at time of check for valid irqs, maybe due to some hardware race on some setups? The problem only seems to happen on some machine + card combos sometimes, e.g., never happened during my testing of different PC cards of the DCE-2/3/4 generation a year ago, but happens consistently now on two different Apple Mac cards (RV730, DCE-3, Apple iMac and Evergreen JUNIPER, DCE-4 in a Apple MacPro). It also doesn't happen at each interrupt but only occassionally every couple of hundred or thousand vblank interrupts. This results in XOrg warning messages like "[ 7084.472] (WW) RADEON(0): radeon_dri2_flip_event_handler: Pageflip completion event has impossible msc 420120 < target_msc 420121" as well as skipped frames and problems for applications that use kms pageflip events or vblank events, e.g., users of DRI2 and DRI3/Present, Waylands Weston compositor, etc. See also https://bugs.freedesktop.org/show_bug.cgi?id=85203 After some talking to Alex and Michel, we decided to fix this by turning the double-check for asserted irq status bits into a warning. Whenever a irq event is queued in the IH ring, always execute the corresponding interrupt handler. Still check the irq status bits, but only to log a DRM_DEBUG message on a mismatch. This fixed the problems reliably on both previously failing cards, RV-730 dual-head tested on both crtcs (pipes D1 and D2) and a triple-output Juniper HD-5770 card tested on all three available crtcs (D1/D2/D3). The r600 and evergreen irq handling is therefore tested, but the cik an si handling is only compile tested due to lack of hw.

radeon: Fix system hang issue when using KMS with older cards The current radeon driver initialization routines, when using KMS, are written so that the IRQ installation routine is called before initializing the WB buffer and the CP rings. With some ASICs, though, the IRQ routine tries to access the GFX_INDEX ring causing a call to RREG32 with the value of -1 in radeon_fence_read. This, in turn causes the system to completely hang with some cards, requiring a hard reset. A call stack that can cause such a hang looks like this (using rv515 ASIC for the example here): * rv515_init (rv515.c) * radeon_irq_kms_init (radeon_irq_kms.c) * drm_irq_install (drm_irq.c) * radeon_driver_irq_preinstall_kms (radeon_irq_kms.c) * rs600_irq_process (rs600.c) * radeon_fence_process - due to SW interrupt (radeon_fence.c) * radeon_fence_read (radeon_fence.c) * hang due to RREG32(-1) The patch moves the IRQ installation to the card startup routine, after the ring has been initialized, but before the IRQ has been set. This fixes the issue, but requires a check to see if the IRQ is already installed, as is the case in the system resume codepath. I have tested the patch on three machines using the rv515, the rv770 and the evergreen ASIC. They worked without issues. This seems to be a known issue and has been reported on several bug tracking sites by various distributions (see links below). Most of reports recommend booting the system with KMS disabled and then enabling KMS by reloading the radeon module. For some reason, this was indeed a usable workaround, however, UMS is now deprecated and disabled by default.
