* drm/radeon: Update pitch for page flipZhenneng Li2021-08-061-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When primary bo is updated, crtc's pitch may have not been updated, this will lead to show disorder content when user changes display mode, we update crtc's pitch in page flip to avoid this bug. This refers to amdgpu's pageflip. v1->v2: Update all of the pitch in all of the page_flip functions in radeon rather than just the evergreen one. v2->v3: Update pitch set method for r100 according to radeon_legacy_crtc.c Cc: Alex Deucher <alexander.deucher@amd.com> Cc: "Christian König" <christian.koenig@amd.com> Cc: "Pan, Xinhui" <Xinhui.Pan@amd.com> Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: amd-gfx@lists.freedesktop.org Cc: dri-devel@lists.freedesktop.org Cc: linux-kernel@vger.kernel.org Signed-off-by: Zhenneng Li <lizhenneng@kylinos.cn> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

* drm/radeon: Retry DDC probing on DVI on failure if we got an HPD interruptLyude2015-12-041-1/+1
| | | | | | | | | | | | | | | | | | | | | HPD signals on DVI ports can be fired off before the pins required for DDC probing actually make contact, due to the pins for HPD making contact first. This results in a HPD signal being asserted but DDC probing failing, resulting in hotplugging occasionally failing. This is somewhat rare on most cards (depending on what angle you plug the DVI connector in), but on some cards it happens constantly. The Radeon R5 on the machine used for testing this patch for instance, runs into this issue just about every time I try to hotplug a DVI monitor and as a result hotplugging almost never works. Rescheduling the hotplug work for a second when we run into an HPD signal with a failing DDC probe usually gives enough time for the rest of the connector's pins to make contact, and fixes this issue.

* radeon: Fix system hang issue when using KMS with older cardsAdis Hamzić2013-06-031-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
