drm/sysfb: Use preferred panel size for panel orientation quirks
Sysfb drivers currently use the given display mode for looking up the panel orientation. But the look-up table stores the native geometry of the panels, so the lookup fails if the current mode sizes differs.

firmware/sysfb: Remove rotation quirk for Lenovo D330
The Lenovo D330 is a notebook with detachable display. The display is installed in landscape orientation, but the display mode is in portrait orientation. By default, the display output is rotated to the left by 90°. The sysfb quirk breaks the display by swapping display width and height; and thus mixing up the display geometry. Fix this by keeping the display as-is. The sysfb DRM drivers, usually efidrm, will pick the correct panel orientation for the display. The exact behavior might depend on the version of the BIOS release, but the exact version numbers of broken and good releases are unknown. Users are advised to update to the latest firmware. Tested on a Lenovo D330-10IGM IdeaPad with firmware 8NCN43WW. v3: - mention possible dependency on BIOS release in commit description Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Ard Biesheuvel <ardb@kernel.org> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patch.msgid.link/20260904090850.43060-2-tzimmermann@suse.de |

drm/hibmc: Set up vblank event to be send on the next vblank
Do not send the vblank event when the page flip completes, but when the vblank interrupt fires. Sending the vblank event at the wrong time can break synchronization of the display update with the vblank period. Use the vblank helper drm_crtc_vblank_atomic_flush(), which sets up the vblank event accordingly. In case of an error, it still sends out the vblank event immediately; thus not starving consumers.

drm/bridge: analogix_dp: Add support for optional data-lanes mapping
Parse the optional 'data-lanes' device tree property to support custom physical lane mapping configuration. If no valid configuration is found, fall back to the default lane map (0, 1, 2, 3) automatically and keep the driver running. Lane mapping is mainly used for below scenarios: 1. Correct PCB lane swap and differential line routing crossover without hardware changes; 2. Adapt mismatched lane pin definitions between SoC and eDP panel; 3. Support multiple panel hardware variants on the same board by configuring data-lanes in device tree only.

drm/bridge: analogix_dp: Restore mandatory samsung DP DT properties
Revert the change that made samsung,link-rate and samsung,lane-count
optional for Exynos DP. Add error checking to fail probe early if the
required DT properties are missing.
If these properties are missing, video_info->max_link_rate and
video_info->max_lane_count remain zero, and so do link_train.link_rate
and link_train.lane_count used in the subsequent link training flow,
resulting in link training failure.
There is no way at all a device can work without these properties.
Here is the code flow when either max_link_rate or max_lane_count is 0:
analogix_dp_commit()
-> analogix_dp_full_link_train(dp, max_lanes = 0, max_rate = 0)
analogix_dp_full_link_train(max_lanes, max_rate):
// Read sink capabilities via DPCD and sanitize them
link_rate = read_dpcd(DP_MAX_LINK_RATE); // >= 0x06 after fixup
lane_count = read_dpcd(DP_MAX_LANE_COUNT); // >= 1 after fixup
// Clamp by the limits from DT
if (link_rate > max_rate) // 0x06 > 0, always true
link_rate = max_rate; // link_rate = 0
if (lane_count > max_lanes) // 1 > 0, always true
lane_count = max_lanes; // lane_count = 0
// Configure TX with the zeroed values
set_link_bandwidth(link_rate = 0)
// writel() is only executed for bwtype == 0x06/0x0a,
// so LINK_BW_SET is never written and stays at
// reset value; phy_configure() gets link_rate = 0.
set_lane_count(lane_count = 0)
// writel(0, ANALOGIX_DP_LANE_COUNT_SET) enables 0 lanes;
// phy_configure() is called with lanes = 0.
// Program sink for link training
drm_dp_dpcd_write(DP_LINK_BW_SET, {link_rate = 0/lane_count = 0})
// DP spec requires link rate in {0x06, 0x0a, 0x14} and
// lane count in {1, 2, 4}. Writing zeros is illegal, so
// the sink cannot enter the training state.
// Training loop
for (lane = 0; lane < lane_count /* 0 */; lane++)
// loop body never executes; training_lane[] stays
// uninitialized and no training register is programmed
Since the sanitized sink values are always non-zero (link_rate >= 0x06,
lane_count >= 1), the clamping with a zero maximum unconditionally
forces the training parameters to zero. Clock recovery can never be
achieved, so link training fails deterministically.
Consequently, making these properties mandatory again cannot break
any existing device: a DT without them could never have worked in
the first place. Failing probe early with a clear error message is
more helpful than a silent link training failure at runtime.

drm/bridge: lontium: Drop redundant vendor prefix from I2C device name
Device names for i2c_device_id are not OF compatibles and have a meaning only for in-tree users (which there are no except the driver itself), thus vendor prefix in this name is completely redundant. It is actually a discouraged pattern because for OF platforms it allows matching driver by I2C bus, instead of OF, thus hiding incomplete way of obtaining driver match data (lack of i2c_get_match_data() usage).

tracing fixes for v7.3:
- Fix several tracefs files that did not take the trace_array reference A trace instance can be created and destroyed in the tracefs "instances" directory via mkdir and rmdir respectively. The instance is represented by a trace_array descriptor. Most tracefs files pass the trace_array as the private data of the inode to the open/read/write functions. Since there is no locking between the time a task opens a file and the deletion of the instance (and the freeing of the trace_array), each open needs to get a reference to the trace_array and each close must remove it. A instance can't be removed if there's any reference taken on its trace_array. The open function uses trace_array_get() that takes a lock (preventing removal of instances) and iterates the list of all existing trace_arrays and if it finds a match, it takes the reference and releases the lock. If it doesn't find a match, it causes the open to return -ENODEV. There were some added files that did not take the trace_array reference on open that needed to be fixed. Sashiko also correctly pointed out that there were some files that took an address of an field or element of the trace_array which had a pointer back to the trace_array to take its reference on open. But this leaves a slight race between referencing this element to get the trace_array as the element itself could be freed. To solve this, some helper functions were created to look for trace_arrays with this field or element in the search so that the element did not have to be dereferenced before the trace_array's reference was taken. - Add a lock around ftrace_ops initialization When a ftrace_ops is first used by ftrace, some internal initialization is performed on the ops. But if multiple tasks were calling functions that did this initialization, it could race and perform doing the initialization more than once, corrupting the internal data. Add a lock in the initialization code to prevent this from happening. - Fix splice reads on mmapped buffers The logic in the ring buffer splice code for mmapped buffers is supposed to do a copy of the memory as the mapped buffers can't be given to splice. But there was an if statement within the copy code that would return a -1 if a request for a full page was done and it wasn't a partial read. This is because this logic was written before mmapped buffers existed and this case didn't make sense at the time. For mmapped buffers it makes perfect sense and by returning early can drop a lot of pages unnecessarily. - Have the persistent ring buffer validation check nr_subbufs Sashiko reported that the validation code was relying on the saved nr_subbufs to match the calculated nr_pages + 1 and if they were off, that the code could cause corruption. Sashiko is correct, and the saved nr_subbufs should be validated before assuming it is correct. - Do not allow more than one instance with the same name on cmdline If an admin were to add more than one trace instances with the same name they all would be created, but only the first one would be accessible via tracefs. This used to not be allowed but some restructuring of code has since made it possible. - Fix the race between subbuf resize and trace_pipe_raw readers If a task was reading trace_pipe_raw while another task was changing the ring buffer subbuf size, it could crash the reader. The trace_pipe_raw readers do get their own copy of the page from the buffer, but the code needs some restructuring to not have the resize of the subbuffers cause issues. - Cap the size of the mapped (static) ring buffer nr_pages The meta data used for ring buffer mapped buffers is 32 bit in size. A normal ring buffer could (in theory) have more than 4 billion pages. But this is not allowed by mapped buffers, so enforce it. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCap3GJRQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qtAfAP9hDPtzctAoz+IHZq+GYejhKTu99ICG vAxTOZivuG6KYAD/UPA4P7z5ayxGM5UlT+2U81+mpCd55F2oFiIxRuFYcwk= =/d+T -----END PGP SIGNATURE----- Merge tag 'trace-v7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix several tracefs files that did not take the trace_array reference A trace instance can be created and destroyed in the tracefs "instances" directory via mkdir and rmdir respectively.

selftests/bpf: Test pointer bpf_loop iteration count rejection
Add a verifier test that leaves the raw tracepoint context pointer in R1 when calling bpf_loop(). This is the smallest trigger for the incorrect precision backtracking: it reuses an existing callback and needs no maps or userspace setup. Expect an ordinary scalar-type rejection. Without the verifier fix, the test instead reaches precision backtracking and reports an internal "backtracking misuse" error.

bpf: Reject non-scalar bpf_loop iteration counts
bpf_loop() declares its nr_loops argument as ARG_ANYTHING. Privileged programs may pass pointer values to such arguments, so check_func_arg() lets a pointer-valued R1 reach the helper-specific checks. Since commit |

virtio_console: allocate the port_buffer with the caller's gfp
put_chars() runs from the hvc console write path with preemption
disabled, so it asks alloc_buf() for GFP_ATOMIC. Only the data buffer
gets it: the struct port_buffer itself keeps the GFP_KERNEL default, so
the allocation can enter direct reclaim and sleep. A write to /dev/kmsg
on a CONFIG_DEBUG_ATOMIC_SLEEP kernel splats:

treewide: refresh kmalloc_obj() conversions
This is another run of the Coccinelle script for converting kmalloc() family of allocations to kmalloc_obj() via the existing rules in scripts/coccinelle/api/kmalloc_objs.cocci This catches both the set of kmalloc() uses added since the first kmalloc_obj() conversions in v7.0 and adds a large group missed in the first pass due to Coccinelle not interacting well with the cleanup.h scoped_...() family of macros[1]. I worked around this with spatch's "--macro-file" argument to a file with all the scoped_...() macros mapped to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control flow indicator I could find. Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc, riscv, and s390 with no new warnings.

Merge branch 'bpf-add-missing-precision-propagation-after-bpf_register_is_null-calls'
Eduard Zingerman says: ==================== bpf: add missing precision propagation after bpf_register_is_null calls Fix [1] uncovered a host of locations where the call to bpf_register_is_null() is not followed by a call to bpf_mark_chain_precision(). check_map_kptr_access() is omitted as it is handled [2] by another series.

bpf: propagate mark_chain_precision() errors out of loop_flag_is_zero()
Stop verification if mark_chain_precision() fails when called from
loop_flag_is_zero(). No functional change intended for the paths where
backtracking succeeds.

bpf: mark a NULL BTF_ID argument of a global subprogram precise
btf_check_func_arg_match() accepts a NULL register for an
ARG_PTR_TO_BTF_ID argument tagged __arg_nullable and skips
check_reg_type() and check_func_arg_reg_off() without marking the
register precise. Hence a checkpoint created on such a path would
prune against arbitrary scalar value.

bpf: mark a NULL kfunc argument precise
check_kfunc_arg() allows bpf_register_is_null() for nullable arguments
w/o marking the underlying scalar register precise. Hence a checkpoint
created on such a path would prune against arbitrary scalar value.
