2018-09-11drm/vkms: Compute CRC with Cursor PlaneHaneen Mohammed
This patch compute CRC for output frame with cursor and primary plane. Blend cursor with primary plane and compute CRC on the resulted frame. This currently passes cursor-size-change, and cursor-64x64-[onscreen, offscreen, sliding, random, dpms, rapid-movement] from igt kms_cursor_crc tests.

2018-09-11staging: vboxvideo: Change address of scanout buffer on page-flipHans de Goede
Commit 2408898e3b6c ("staging: vboxvideo: Add page-flip support") only calls vbox_crtc_do_set_base() on page-flips, but despite that function's name it only pins the new fb, unpins the old fb and sets vbox_crtc->fb_offset. It does not program the hardware to scan out at the new vbox_crtc->fb_offset value. This was causing only every other frame (assuming page-flipping between 2 buffers) to be shown since we kept scanning out of the old (now unpinned!) buffer. This commit fixes this by adding code to vbox_crtc_page_flip() to tell the hardware to scanout from the new fb_offset.

2018-09-11staging: vboxvideo: Fix IRQs no longer workingHans de Goede
Commit 1daddbc8dec5 ("staging: vboxvideo: Update driver to use drm_dev_register.") replaced the obsolere drm_get_pci_dev() with normal pci probe and remove functions. But the new vbox_pci_probe() is missing a pci_enable_device() call, causing interrupts to not be delivered. This causes resizes of the vm window to not get seen by the drm/kms code. This commit adds the missing pci_enable_device() call, fixing this. Fixes: 1daddbc8dec5 ("staging: vboxvideo: Update driver to use ...")

2018-09-11of: fix phandle cache creation for DTs with no phandlesRob Herring
With commit 0b3ce78e90fc ("of: cache phandle nodes to reduce cost of of_find_node_by_phandle()"), a G3 PowerMac fails to boot. The root cause is the DT for this system has no phandle properties when booted with BootX. of_populate_phandle_cache() does not handle the case of no phandles correctly. The problem is roundup_pow_of_two() for 0 is undefined. The implementation subtracts 1 underflowing and then things are in the weeds.

2018-09-11PCI: pciehp: Fix hot-add vs powerfault detection orderKeith Busch
If both hot-add and power fault were observed in a single interrupt, we handled the hot-add first, then the power fault, in this path: pciehp_ist if (events & (PDC | DLLSC)) pciehp_handle_presence_or_link_change case OFF_STATE: pciehp_enable_slot __pciehp_enable_slot board_added pciehp_power_on_slot ctrl->power_fault_detected = 0 pcie_write_cmd(ctrl, PCI_EXP_SLTCTL_PWR_ON, PCI_EXP_SLTCTL_PCC) pciehp_green_led_on(p_slot) # power LED on pciehp_set_attention_status(p_slot, 0) # attention LED off if ((events & PFD) && !ctrl->power_fault_detected) ctrl->power_fault_detected = 1 pciehp_set_attention_status(1) # attention LED on pciehp_green_led_off(slot) # power LED off This left the attention indicator on (even though the hot-add succeeded) and the power indicator off (even though the slot power was on). Fix this by checking for power faults before checking for new devices. Prior to 0e94916e6091, this was successful because everything was chained through work queues and the order was: INT_PRESENCE_ON -> INT_POWER_FAULT -> ENABLE_REQ The ENABLE_REQ cleared the power fault at the end, but now everything is handled inline with the interrupt thread, such that the work ENABLE_REQ was doing happens before power fault handling now.

2018-09-11drm/fb: Stop leaking physical addressDaniel Vetter
For buffer sharing, use dma-buf instead. We can't set smem_start to 0 unconditionally since that's used by the fbdev mmap default implementation. And we have plenty of userspace which would like to keep that working. This might break legit userspace - if it does we need to look at a case-by-cases basis how to handle that. Worst case I expect overrides for only specific drivers, since anything remotely modern should be using dma-buf/prime now (which is about 7 years old now for DRM drivers). This issue was uncovered because Noralf's rework to implement a generic fb_probe also implements it's own fb_mmap callback. Which means smem_start didn't have to be set anymore, which blew up some blob in userspace rather badly.

2018-09-11fbdev: Add FBINFO_HIDE_SMEM_START flagDaniel Vetter
DRM drivers really, really, really don't want random userspace to share buffer behind it's back, bypassing the dma-buf buffer sharing machanism. For that reason we've ruthlessly rejected any IOCTL exposing the physical address of any graphics buffer. Unfortunately fbdev comes with that built-in. We could just set smem_start to 0, but that means we'd have to hand-roll our own fb_mmap implementation. For good reasons many drivers do that, but smem_start/length is still super convenient. Hence instead just stop the leak in the ioctl, to keep fb mmap working as-is. A second patch will set this flag for all drm drivers.

2018-09-11fbdev: Drop FBINFO_CAN_FORCE_OUTPUT flagDaniel Vetter
This was only added for the drm's fbdev emulation support, so that it would try harder to show the Oops. Unfortunately this never really worked reliably, and in practice ended up pushing the real Oops off the screen due to plentyfull locking, sleep-while-atomic and other issues. So we removed all that support from the fbdev emulation a while back. Aside: We've also removed the kgdb support, for similar reasons. Since it's such a small patch I figured I don't split this up into the usual 3-phase removal.

2018-09-10drm/amdgpu/gmc9: Adjust GART and AGP location with xgmi offset (v2)Alex Deucher
On hives with xgmi enabled, the fb_location aperture is a size which defines the total framebuffer size of all nodes in the hive. Each GPU in the hive has the same view via the fb_location aperture. GPU0 starts at offset (0 * segment size), GPU1 starts at offset (1 * segment size), etc. For access to local vram on each GPU, we need to take this offset into account. This including on setting up GPUVM page table and GART table v2: squash in "drm/amdgpu: Init correct fb region for none XGMI configuration" Acked-by: Huang Rui <ray.huang@amd.com> Acked-by: Slava Abramov <slava.abramov@amd.com> Signed-off-by: Shaoyun Liu <Shaoyun.Liu@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Felix Kuehling <Felix.Kuehling@amd.com> Acked-by: Huang Rui <ray.huang@amd.com>
