The parent device of the iGPU is the root port for which bridge_d3 is false. This accidentally enables the legacy PM method which conflicts with port PM and prevented the dGPU from powering on.

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When PCIe port PM is not enabled (system BIOS is pre-2015 or the pcie_port_pm=off parameter is set), legacy ATPX PM should still be marked as supported. Otherwise the GPU can fail to power on after runtime suspend. This affected a Dell Inspiron 5548. Ideally the BIOS date in the PCI core is lowered to 2013 (the first year where hybrid graphics platforms using power resources was introduced), but that seems more risky at this point and would not solve the pcie_port_pm=off issue. v2: agd: fix typo Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=98505 Signed-off-by: Peter Wu <peter@lekensteyn.nl> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: <stable@vger.kernel.org> # 4.8+ Reviewed-by: Alex Deucher <alexander.deucher@amd.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit a481daa88fd4 ("drm/radeon: always apply pci shutdown callbacks"), a Dell Latitude D600 laptop has crashed on shutdown. The PCI Identification of the graphics adapter is "VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] RV250/M9 GL [Mobility FireGL 9000/Radeon 9000] [1002:4c66] (rev 01)". Prior to commit b0c80bd5d2e3 ("drm/radeon: fix up dp aux tear down (v2)"), I have no idea where the panic happened as the screen was blanked before the crash. Since that more recent change, the panic has been in routine radeon_connector_unregister(), and has been shown to be due to a NULL value in the ddc_bus member of struct drm_connector.

Rob Clark also noticed it was also allocating GFP_KERNEL memory in atomic contexts, breaking them. Instead of having to allocate GFP_ATOMIC memory and fixing the callers to make them cleanup the memory afterwards, let's change the function's signature by having the caller take care of the memory and passing it to the function. The new parameter is a single-field struct in order to enforce the size of its buffer and help callers to correctly manage their memory.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The read is taking a considerable amount of time (about 50us on this machine). The register does not ever hold anything other than the ring ID that is updated in this exact function, so there is no need for the read modify write cycle. This chops off a big chunk of the time spent in hardirq disabled context, as this function is called multiple times in the interrupt handler. With this change applied radeon won't show up in the list of the worst IRQ latency offenders anymore, where it was a regular before.

The purpose of this change is to make the use of FOLL_FORCE explicit so it is easier to grep for and clearer to callers that this flag is being used. The use of FOLL_FORCE is an issue as it overrides missing VM_READ/VM_WRITE flags for the VMA whose pages we are reading from/writing to, which can result in surprising behaviour. The patch series came out of the discussion around commit 38e088546522 ("mm: check VMA flags to avoid invalid PROT_NONE NUMA balancing"), which addressed a BUG_ON() being triggered when a page was faulted in with PROT_NONE set but having been overridden by FOLL_FORCE. do_numa_page() was run on the assumption the page _must_ be one marked for NUMA node migration as an actual PROT_NONE page would have been dealt with prior to this code path, however FOLL_FORCE introduced a situation where this assumption did not hold. See https://marc.info/?l=linux-mm&m=147585445805166 for the patch proposal" Additionally, there's a fix for an ancient bug related to FOLL_FORCE and FOLL_WRITE by me.

This causes a race if pageflip ioctl is called close to vblank: 1. pageflip ioctl queues execution of radeon_flip_work_func. 2. vblank irq fires, radeon_crtc_handle_vblank checks for flip_status == FLIP_SUBMITTED finds none, no-ops. 3. radeon_flip_work_func runs inside vblank, decides to set flip_status == FLIP_SUBMITTED and programs the flip into hw. 4. hw executes flip immediately (because in vblank), but as 2 already happened, the flip completion routine only emits the flip completion event one refresh later -> wrong vblank count/timestamp for completion and no performance gain, as instead of delaying the flip until next vblank, we now delay the next flip by 1 refresh while waiting for the delayed flip completion event. Given we often don't gain anything due to this race, but lose precision, prevent the programmed flip from executing in vblank on pre DCE4 asics to avoid this race. On pre-AVIVO hw we can't program the hw for edge-triggered flips, they always execute anywhere in vblank. Therefore delay the actual flip programming until after vblank on pre-AVIVO.

As vblank irqs fire a bit before start of vblank (when the linebuffer fifo read position reaches end of scanout), we have some fudge for flip completion handling in the last lines of active scanout. Old code assumed the threshold to be 99% of active scanout height, a ballpark estimate which worked ok. Since we know since a while how to calculate the actual threshold from linebuffer size, lets make use of it to get a more accurate threshold. This completion path is still prone to some races in corner cases, especially on pre-AVIVO hardware, so document them a bit better in the code comments.
