2024-10-28cxl: downgrade a warning message to debug level in cxl_probe_component_regs()Coly Li
In cxl_probe_component_regs() the error message "Couldn't locate the CXL.cache and CXL.mem capability array header." is potentially a false positive error condition. Downgrade the message from error level to debug level by using dev_dbg() to print the message, and the end users won't worry about the message anymore.

2024-10-28cxl/pci: Add sysfs attribute for CXL 1.1 device link statusKobayashi,Daisuke
Add sysfs attribute for CXL 1.1 device link status to the cxl pci device. In CXL1.1, the link status of the device is included in the RCRB mapped to the memory mapped register area. Critically, that arrangement makes the link status and control registers invisible to existing PCI user tooling. Export those registers via sysfs with the expectation that PCI user tooling will alternatively look for these sysfs files when attempting to access to these CXL 1.1 endpoints registers.

2024-10-28cxl/core/regs: Add rcd_pcie_cap initializationKobayashi,Daisuke
Add rcd_pcie_cap and its initialization to cache the offset of cxl1.1 device link status information. By caching it, avoid the walking memory map area to find the offset when output the register value. Given that this solution involves port lookups via cxl_pci_find_port() and multiple exit paths where that reference needs to be dropped, introduce a new put_cxl_root() scope-based-free handler.

2024-10-28drm/msm/a6xx: Fix excessive stack usageAkhil P Oommen
Clang-19 and above sometimes end up with multiple copies of the large a6xx_hfi_msg_bw_table structure on the stack. The problem is that a6xx_hfi_send_bw_table() calls a number of device specific functions to fill the structure, but these create another copy of the structure on the stack which gets copied to the first. If the functions get inlined, that busts the warning limit: drivers/gpu/drm/msm/adreno/a6xx_hfi.c:631:12: error: stack frame size (1032) exceeds limit (1024) in 'a6xx_hfi_send_bw_table' [-Werror,-Wframe-larger-than] Fix this by kmalloc-ating struct a6xx_hfi_msg_bw_table instead of using the stack. Also, use this opportunity to skip re-initializing this table to optimize gpu wake up latency.

2024-10-28drm/etnaviv: Map and unmap GPUVA range with respect to the GPUVA sizeSui Jingfeng
Etnaviv assumes that GPU page size is 4KiB, however, GPUVA ranges collision when using softpin capable GPUs on a non 4KiB CPU page size configuration. The root cause is that kernel side BO takes up bigger address space than userspace expect, the size of backing memory of GEM buffer objects are required to align to the CPU PAGE_SIZE. Therefore, results in userspace allocated GPUVA range fails to be inserted to the specified hole exactly. To solve this problem, record the GPU visiable size of a BO firstly, then map and unmap the SG entry strictly with respect to the total GPUVA size.

A later change will use the FE debug registers to improve GPU progress monitoring. Instead of having to keep track of the usage state of the debug registers and lock access to the VIVS_HI_CLOCK_CONTROL register, statically enable debug register access during GPU init. The Vivante downstream driver seems to do the same thing since a while, so it should be okay to keep access enabled. (See gckHARDWARE_InitializeHardware in 6.4.11 downstream driver). Many debug registers contain bogus data if clock gating is enabled, so even if they are always accessible performance profiling still needs to manage some prerequisites.

2024-10-28media: v4l2-core: v4l2-dv-timings: check cvt/gtf resultHans Verkuil
The v4l2_detect_cvt/gtf functions should check the result against the timing capabilities: these functions calculate the timings, so if they are out of bounds, they should be rejected. To do this, add the struct v4l2_dv_timings_cap as argument to those functions. This required updates to the adv7604 and adv7842 drivers since the prototype of these functions has now changed. The timings struct that is passed to v4l2_detect_cvt/gtf in those two drivers is filled with the timings detected by the hardware. The vivid driver was also updated, but an additional check was added: the width and height specified by VIDIOC_S_DV_TIMINGS has to match the calculated result, otherwise something went wrong. Note that vivid *emulates* hardware, so all the values passed to the v4l2_detect_cvt/gtf functions came from the timings struct that was filled by userspace and passed on to the driver via VIDIOC_S_DV_TIMINGS. So these fields can contain random data. Both the constraints check via struct v4l2_dv_timings_cap and the additional width/height check ensure that the resulting timings are sane and not messed up by the v4l2_detect_cvt/gtf calculations.

The driver configures mostly Pixel PLL from the clock cached in local copy of the mode. Make sure the driver uses adjusted mode which contains the updated Pixel PLL settings negotiated in tc_dpi_atomic_check()/tc_edp_atomic_check().

2024-10-28net: dsa: mv88e6xxx: fix unreleased fwnode_handle in setup_port()Javier Carrasco
'ports_fwnode' is initialized via device_get_named_child_node(), which requires a call to fwnode_handle_put() when the variable is no longer required to avoid leaking memory. Add the missing fwnode_handle_put() after 'ports_fwnode' has been used and is no longer required.

2024-10-28pinctrl: spacemit: fix double free of mapDan Carpenter
The map pointer is freed by pinctrl_utils_free_map(). It must not be a devm_ pointer or it leads to a double free when the device is unloaded. This is similar to a couple bugs Harshit Mogalapalli fixed earlier in commits 3fd976afe974 ("pinctrl: nuvoton: fix a double free in ma35_pinctrl_dt_node_to_map_func()") and 4575962aeed6 ("pinctrl: sophgo: fix double free in cv1800_pctrl_dt_node_to_map()").

2024-10-28mmc: bcm2835: Introduce proper clock handlingStefan Wahren
The custom sdhost controller on BCM2835 is feed by the critical VPU clock. In preparation for PM suspend/resume support, add a proper clock handling to the driver like in the other clock consumers (e.g. I2C). Move the clock handling behind mmc_of_parse(), because it could return with -EPROBE_DEFER and we want to minimize potential clock operation during boot phase.
