539aae6 Robin Murphy 06 June 2016, 07:11:52 UTC drm/nouveau/Revert "drm/nouveau/device/pci: set as non-CPU-coherent on ARM64" This reverts commit 1733a2ad36741b1812cf8b3f3037c28d0af53f50. There is apparently something amiss with the way the TTM code handles DMA buffers, which the above commit was attempting to work around for arm64 systems with non-coherent PCI. Unfortunately, this completely breaks systems *with* coherent PCI (which appear to be the majority). Booting a plain arm64 defconfig + CONFIG_DRM + CONFIG_DRM_NOUVEAU on a machine with a PCI GPU having coherent dma_map_ops (in this case a 7600GT card plugged into an ARM Juno board) results in a fatal crash: [ 2.803438] nouveau 0000:06:00.0: DRM: allocated 1024x768 fb: 0x9000, bo ffffffc976141c00 [ 2.897662] Unable to handle kernel NULL pointer dereference at virtual address 000001ac [ 2.897666] pgd = ffffff8008e00000 [ 2.897675] [000001ac] *pgd=00000009ffffe003, *pud=00000009ffffe003, *pmd=0000000000000000 [ 2.897680] Internal error: Oops: 96000045 [#1] PREEMPT SMP [ 2.897685] Modules linked in: [ 2.897692] CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.6.0-rc5+ #543 [ 2.897694] Hardware name: ARM Juno development board (r1) (DT) [ 2.897699] task: ffffffc9768a0000 ti: ffffffc9768a8000 task.ti: ffffffc9768a8000 [ 2.897711] PC is at __memcpy+0x7c/0x180 [ 2.897719] LR is at OUT_RINGp+0x34/0x70 [ 2.897724] pc : [<ffffff80083465fc>] lr : [<ffffff800854248c>] pstate: 80000045 [ 2.897726] sp : ffffffc9768ab360 [ 2.897732] x29: ffffffc9768ab360 x28: 0000000000000001 [ 2.897738] x27: ffffffc97624c000 x26: 0000000000000000 [ 2.897744] x25: 0000000000000080 x24: 0000000000006c00 [ 2.897749] x23: 0000000000000005 x22: ffffffc97624c010 [ 2.897755] x21: 0000000000000004 x20: 0000000000000004 [ 2.897761] x19: ffffffc9763da000 x18: ffffffc976b2491c [ 2.897766] x17: 0000000000000007 x16: 0000000000000006 [ 2.897771] x15: 0000000000000001 x14: 0000000000000001 [ 2.897777] x13: 0000000000e31b70 x12: ffffffc9768a0080 [ 2.897783] x11: 0000000000000000 x10: fffffffffffffb00 [ 2.897788] x9 : 0000000000000000 x8 : 0000000000000000 [ 2.897793] x7 : 0000000000000000 x6 : 00000000000001ac [ 2.897799] x5 : 00000000ffffffff x4 : 0000000000000000 [ 2.897804] x3 : 0000000000000010 x2 : 0000000000000010 [ 2.897810] x1 : ffffffc97624c010 x0 : 00000000000001ac ...

And only the reference count of connectors that were previously bound to an encoder and are unbound afterwards should ever be decremented. The reference counts of the temporary copies in the save_connectors should not be touched at all. This patch fixes the above error by only incrementing the reference count of those connectors in the set that are initially not bound to any encoder, and also by restoring the reference count of only those connectors in the set in the failure case. "Note that this can only be hit when fbdev emulation is disabled, since then the refcount drops from 1 to 0 and we call the connector destroy functions on the backup copy, which eventually results in tears. With fbdev emulation the refcount only goes down from 2 to 1 ever. And since we unconditionally increment the refcount on the real object, the refcount of that will slowly increase. The backup connector's refcount doesn't matter, since we kfree() that either way in the end of drm_crtc_helper_set_config()."

Unfortunately one of the sideaffects of having the refclk for a DPLL set to SSC is that as long as it's set to SSC, the GPU will prevent us from powering down any of the pipes or transcoders using it. A couple of BIOSes enable SSC in both PCH_DREF_CONTROL and in the DPLL configurations. This causes issues on the first modeset, since we don't expect SSC to be left on and as a result, can't successfully power down the pipes or the transcoders using it. Here's an example from this Dell OptiPlex 990: [drm:intel_modeset_init] SSC enabled by BIOS, overriding VBT which says disabled [drm:intel_modeset_init] 2 display pipes available.

Looking at some dumps those appear to be the physical dimensions in mm. Which makes sense since the timing descriptor matches the format used by EDID detailed timing descriptor, which defines these as "H/V Addressable Video Image Size in mm". So let's use that information from the panel fixed mode to get the physical dimensions for LVDS/eDP/DSI displays.

fff7660 Chris Wilson 01 June 2016, 07:27:50 UTC drm/i915: Only ignore eDP ports that are connected If the VBT says that a certain port should be eDP (and hence fused off from HDMI), but in reality it isn't, we need to try and acquire the HDMI connection instead. So only trust the VBT edp setting if we can connect to an eDP device on that port.

Let's fiddle with the version matching such that it works with this VBT (i.e. treat BIOS v110 as having the same size as v108). Fixes [drm:intel_bios_init] *ERROR* Unexpected child device config size 27 (expected 33 for VBT version 110) Whether this is correct, no one knows - but it works for this particular machine.

However, allocations in an atomic context (e.g. when a spinlock is held) are not allowed. The function regmap_write calls map->lock, which acquires a spinlock in the fast_io case. Since the FSL DCU driver uses MMIO, the regmap bus of type regmap_mmio is being used which has fast_io set to true.

56d1fe0 Mario Kleiner 18 May 2016, 12:02:46 UTC drm/vc4: Make pageflip completion handling more robust. Protect both the setup of the pageflip event and the latching of the new requested displaylist head pointer by the event lock, so we can't get into a situation where vc4_atomic_flush latches the new display list via HVS_WRITE, then immediately gets preempted before queueing the pageflip event, then the page-flip completes in hw and the vc4_crtc_handle_page_flip() runs and no-ops due to lack of a pending pageflip event, then vc4_atomic_flush continues and only then queues the pageflip event - after the page flip handling already no-oped. This would cause flip completion handling only at the next vblank - one frame too late. In vc4_crtc_handle_page_flip() check the actual DL head pointer in SCALER_DISPLACTX against the requested pointer for page flip to make sure that the flip actually really completed in the current vblank and doesn't get deferred to the next one because the DL head pointer was written a bit too late into SCALER_DISPLISTX, after start of vblank, and missed the boat. This avoids handling a pageflip completion too early - one frame too early. According to Eric, DL head pointer updates which were written into the HVS DISPLISTX reg get committed to hardware at the last pixel of active scanout. Our vblank interrupt handler, as triggered by PV_INT_VFP_START irq, gets to run earliest at the first pixel of HBLANK at the end of the last scanline of active scanout, ie. vblank irq handling runs at least 1 pixel duration after a potential pageflip completion happened in hardware. This ordering of events in the hardware, together with the lock protection and SCALER_DISPLACTX sampling of this patch, guarantees that pageflip completion handling only runs at exactly the vblank irq of actual pageflip completion in all cases. Background info from Eric about the relative timing of HVS, PV's and trigger points for interrupts, DL updates: https://lists.freedesktop.org/archives/dri-devel/2016-May/107510.html Tested on RPi 2B with hardware timing measurement equipment and shown to no longer complete flips too early or too late.

eedf265 Eric W. Biederman 02 June 2016, 15:29:47 UTC devpts: Make each mount of devpts an independent filesystem. The /dev/ptmx device node is changed to lookup the directory entry "pts" in the same directory as the /dev/ptmx device node was opened in. If there is a "pts" entry and that entry is a devpts filesystem /dev/ptmx uses that filesystem. Otherwise the open of /dev/ptmx fails. The DEVPTS_MULTIPLE_INSTANCES configuration option is removed, so that userspace can now safely depend on each mount of devpts creating a new instance of the filesystem. Each mount of devpts is now a separate and equal filesystem. Reserved ttys are now available to all instances of devpts where the mounter is in the initial mount namespace. A new vfs helper path_pts is introduced that finds a directory entry named "pts" in the directory of the passed in path, and changes the passed in path to point to it. The helper path_pts uses a function path_parent_directory that was factored out of follow_dotdot. In the implementation of devpts: - devpts_mnt is killed as it is no longer meaningful if all mounts of devpts are equal. - pts_sb_from_inode is replaced by just inode->i_sb as all cached inodes in the tty layer are now from the devpts filesystem. - devpts_add_ref is rolled into the new function devpts_ptmx. And the unnecessary inode hold is removed. - devpts_del_ref is renamed devpts_release and reduced to just a deacrivate_super. - The newinstance mount option continues to be accepted but is now ignored. In devpts_fs.h definitions for when !CONFIG_UNIX98_PTYS are removed as they are never used. Documentation/filesystems/devices.txt is updated to describe the current situation. This has been verified to work properly on openwrt-15.05, centos5, centos6, centos7, debian-6.0.2, debian-7.9, debian-8.2, ubuntu-14.04.3, ubuntu-15.10, fedora23, magia-5, mint-17.3, opensuse-42.1, slackware-14.1, gentoo-20151225 (13.0?), archlinux-2015-12-01. With the caveat that on centos6 and on slackware-14.1 that there wind up being two instances of the devpts filesystem mounted on /dev/pts, the lower copy does not end up getting used.

Syscalls should never crash programs, but instead return EFAULT. The IIR register contains the executed instruction, which disassebles into "ldw 0(sr3,r5),r9". This load-word instruction is part of __get_user() which tried to read the word at %r5/IOR (0xfa6f7fff). This means the unaligned handler jumped in. The unaligned handler is able to emulate all ldw instructions, but it fails if it fails to read the source e.g. because of page fault. The following program reproduces the problem: #define _GNU_SOURCE #include <unistd.h> #include <sys/syscall.h> #include <sys/mman.h> int main(void) { /* allocate 8k */ char *ptr = mmap(NULL, 2*4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0); /* free second half (upper 4k) and make it invalid. */ munmap(ptr+4096, 4096); /* syscall where first int is unaligned and clobbers into invalid memory region */ /* syscall should return EFAULT */ return syscall(__NR_clock_adjtime, 0, ptr+4095); } To fix this issue we simply need to check if the faulting instruction address is in the exception fixup table when the unaligned handler failed. If it is, call the fixup routine instead of crashing. While looking at the unaligned handler I found another issue as well: The target register should not be modified if the handler was unsuccessful.

be24a89 Mikulas Patocka 28 June 2011, 22:48:19 UTC parisc: Fix backtrace on PA-RISC This patch fixes backtrace on PA-RISC There were several problems: 1) The code that decodes instructions handles instructions that subtract from the stack pointer incorrectly. If the instruction subtracts the number X from the stack pointer the code increases the frame size by (0x100000000-X). This results in invalid accesses to memory and recursive page faults. 2) Because gcc reorders blocks, handling instructions that subtract from the frame pointer is incorrect. For example, this function int f(int a) { if (__builtin_expect(a, 1)) return a; g(); return a; } is compiled in such a way, that the code that decreases the stack pointer for the first "return a" is placed before the code for "g" call. If we recognize this decrement, we mistakenly believe that the frame size for the "g" call is zero. To fix problems 1) and 2), the patch doesn't recognize instructions that decrease the stack pointer at all. To further safeguard the unwind code against nonsense values, we don't allow frame size larger than Total_frame_size. 3) The backtrace is not locked. If stack dump races with module unload, invalid table can be accessed. This patch adds a spinlock when processing module tables. Note, that for correct backtrace, you need recent binutils. Binutils 2.18 from Debian 5 produce garbage unwind tables. Binutils 2.21 work better (it sometimes forgets function frames, but at least it doesn't generate garbage).
