2024-12-23cpufreq: fix using cpufreq-dt as moduleAndreas Kemnade
This driver can be built as a module since commit 3b062a086984 ("cpufreq: dt-platdev: Support building as module"), but unfortunately this caused a regression because the cputfreq-dt-platdev.ko module does not autoload. Usually, this is solved by just using the MODULE_DEVICE_TABLE() macro to export all the device IDs as module aliases. But this driver is special due how matches with devices and decides what platform supports. There are two of_device_id lists, an allow list that are for CPU devices that always match and a deny list that's for devices that must not match. The driver registers a cpufreq-dt platform device for all the CPU device nodes that either are in the allow list or contain an operating-points-v2 property and are not in the deny list. Enforce builtin compile of cpufreq-dt-platdev to make autoload work.

2024-12-23leds: Add LED1202 I2C driverVicentiu Galanopulo
The output current can be adjusted separately for each channel by 8-bit analog (current sink input) and 12-bit digital (PWM) dimming control. The LED1202 implements 12 low-side current generators with independent dimming control. Internal volatile memory allows the user to store up to 8 different patterns, each pattern is a particular output configuration in terms of PWM duty-cycle (on 4096 steps). Analog dimming (on 256 steps) is per channel but common to all patterns. Each device tree LED node will have a corresponding entry in /sys/class/leds with the label name. The brightness property corresponds to the per channel analog dimming, while the patterns[1-8] to the PWM dimming control.

2024-12-23wifi: rtw88: usb: Preallocate and reuse the RX skbsBitterblue Smith
The USB driver uses four USB Request Blocks for RX. Before submitting one, it allocates a 32768 byte skb for the RX data. This allocation can fail, maybe due to temporary memory fragmentation. When the allocation fails, the corresponding URB is never submitted again. After four such allocation failures, all RX stops because the driver is not requesting data from the device anymore. Don't allocate a 32768 byte skb when submitting a USB Request Block (which happens very often). Instead preallocate 8 such skbs, and reuse them over and over. If all 8 are busy, allocate a new one. This is pretty rare. If the allocation fails, use a work to try again later. When there are enough free skbs again, free the excess skbs. Also, use WQ_BH for the RX workqueue. With a normal or high priority workqueue the skbs are processed too slowly when the system is even a little busy, like when opening a new page in a browser, and the driver runs out of free skbs and allocates a lot of new ones. This is more or less what the out-of-tree Realtek drivers do, except they use a tasklet instead of a BH workqueue. Tested with RTL8723DU, RTL8821AU, RTL8812AU, RTL8812BU, RTL8822CU, RTL8811CU.

2024-12-23wifi: rtw88: Handle C2H_ADAPTIVITY in rtw_fw_c2h_cmd_handle()Bitterblue Smith
The firmware message C2H_ADAPTIVITY is currently handled in rtw_fw_c2h_cmd_rx_irqsafe(), which runs in the RX workqueue, but it's not "irqsafe" with USB because it sleeps (reads hardware registers). This becomes a problem after the next patch, which will create the RX workqueue with the flag WQ_BH. To avoid sleeping when it's not allowed, handle C2H_ADAPTIVITY in rtw_fw_c2h_cmd_handle(), which runs in the c2h workqueue.

2024-12-23wifi: rtw88: usb: Copy instead of cloning the RX skbBitterblue Smith
"iperf3 -c 192.168.0.1 -R --udp -b 0" shows about 40% of datagrams are lost. Many torrents don't download faster than 3 MiB/s, probably because the Bittorrent protocol uses UDP. This is somehow related to the use of skb_clone() in the RX path. Don't use skb_clone(). Instead allocate a new skb for each 802.11 frame received and copy the data from the big (32768 byte) skb. With this patch, "iperf3 -c 192.168.0.1 -R --udp -b 0" shows only 1-2% of datagrams are lost, and torrents can reach download speeds of 36 MiB/s. Tested with RTL8812AU and RTL8822CU.

tegra_emc_find_node_by_ram_code() As of_find_node_by_name() release the reference of the argument device node, tegra_emc_find_node_by_ram_code() releases some device nodes while still in use, resulting in possible UAFs. According to the bindings and the in-tree DTS files, the "emc-tables" node is always device's child node with the property "nvidia,use-ram-code", and the "lpddr2" node is a child of the "emc-tables" node. Thus utilize the for_each_child_of_node() macro and of_get_child_by_name() instead of of_find_node_by_name() to simplify the code. This bug was found by an experimental verification tool that I am developing.

2024-12-21staging: gpib: Fix allyesconfig build failuresSteven Rostedt
My tests run an allyesconfig build and it failed with the following errors: LD [M] samples/kfifo/dma-example.ko ld.lld: error: undefined symbol: nec7210_board_reset ld.lld: error: undefined symbol: nec7210_read ld.lld: error: undefined symbol: nec7210_write It appears that some modules call the function nec7210_board_reset() that is defined in nec7210.c. In an allyesconfig build, these other modules are built in. But the file that holds nec7210_board_reset() has: obj-m += nec7210.o Where that "-m" means it only gets built as a module. With the other modules built in, they have no access to nec7210_board_reset() and the build fails. This isn't the only function. After fixing that one, I hit another: ld.lld: error: undefined symbol: push_gpib_event ld.lld: error: undefined symbol: gpib_match_device_path Where push_gpib_event() was also used outside of the file it was defined in, and that file too only was built as a module. Since the directory that nec7210.c is only traversed when CONFIG_GPIB_NEC7210 is set, and the directory with gpib_common.c is only traversed when CONFIG_GPIB_COMMON is set, use those configs as the option to build those modules. When it is an allyesconfig, then they will both be built in and their functions will be available to the other modules that are also built in.

The boot time issue manifests itself when a PCI Express bandwidth control is unnecessarily enabled on the Thunderbolt controller downstream ports, which only supports a link speed of 2.5 GT/s in accordance with USB4 v2 specification (p. 671, sec. 11.2.1, "PCIe Physical Layer Logical Sub-block"). As such, there is no need to enable bandwidth control on such downstream port links, which also works around the issue. Both patches were tested by the original reporter on the hardware on which the failure origin golly manifested itself. Both fixes were proven to resolve the reported boot hang issue, and both patches have been in linux-next this week with no reported problems" * tag 'pci-v6.13-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci: PCI/bwctrl: Enable only if more than one speed is supported PCI: Honor Max Link Speed when determining supported speeds
