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.

Since commit 23c85094fe18 ("proc/kcore: add vmcoreinfo note to /proc/kcore") the kernel has exported the vmcoreinfo PT_NOTE on /proc/kcore as well as /proc/vmcore. arm64 only exposes it's additional arch information via arch_crash_save_vmcoreinfo() if built with CONFIG_KEXEC, as kdump was previously the only user of vmcoreinfo. Move this weak function to a separate file that is built at the same time as its caller in kernel/crash_core.c. This ensures values like 'kimage_voffset' are always present in the vmcoreinfo PT_NOTE.

2018-09-11Revert "printk: make sure to print log on console."Petr Mladek
This reverts commit 375899cddcbb26881b03cb3fbdcfd600e4e67f4a. The visibility of early messages did not longer take into account "quiet", "debug", and "loglevel" early parameters. It would be possible to invalidate and recompute LOG_NOCONS flag for the affected messages. But it would be hairy. Instead this patch just reverts the problematic commit. We could come up with a better solution for the original problem. For example, we could simplify the logic and just mark messages that should always be visible or always invisible on the console. Also this patch reverts the related build fix commit ffaa619af1b06 ("printk: Fix warning about unused suppress_message_printing"). Finally, this patch does not put back the unused LOG_NOCONS flag.

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.
