2024-12-31RDMA/rtrs: Ensure 'ib_sge list' is accessibleLi Zhijian
Move the declaration of the 'ib_sge list' variable outside the 'always_invalidate' block to ensure it remains accessible for use throughout the function. Previously, 'ib_sge list' was declared within the 'always_invalidate' block, limiting its accessibility, then caused a 'BUG: kernel NULL pointer dereference'[1]. ? __die_body.cold+0x19/0x27 ? page_fault_oops+0x15a/0x2d0 ? search_module_extables+0x19/0x60 ? search_bpf_extables+0x5f/0x80 ? exc_page_fault+0x7e/0x180 ? asm_exc_page_fault+0x26/0x30 ? memcpy_orig+0xd5/0x140 rxe_mr_copy+0x1c3/0x200 [rdma_rxe] ? rxe_pool_get_index+0x4b/0x80 [rdma_rxe] copy_data+0xa5/0x230 [rdma_rxe] rxe_requester+0xd9b/0xf70 [rdma_rxe] ? finish_task_switch.isra.0+0x99/0x2e0 rxe_sender+0x13/0x40 [rdma_rxe] do_task+0x68/0x1e0 [rdma_rxe] process_one_work+0x177/0x330 worker_thread+0x252/0x390 ? __pfx_worker_thread+0x10/0x10 This change ensures the variable is available for subsequent operations that require it.

2024-12-30gve: trigger RX NAPI instead of TX NAPI in gve_xsk_wakeupJoshua Washington
Commit ba0925c34e0f ("gve: process XSK TX descriptors as part of RX NAPI") moved XSK TX processing to be part of the RX NAPI. However, that commit did not include triggering the RX NAPI in gve_xsk_wakeup. This is necessary because the TX NAPI only processes TX completions, meaning that a TX wakeup would not actually trigger XSK descriptor processing. Also, the branch on XDP_WAKEUP_TX was supposed to have been removed, as the NAPI should be scheduled whether the wakeup is for RX or TX.

2024-12-30RDMA/erdma: Support create_ah/destroy_ah in non-sleepable contextsBoshi Yu
The RDMA CM module might invoke erdma_create_ah() or erdma_destroy_ah() in a non-sleepable context. Both of these functions will call the erdma_post_cmd_wait(), which can potentially sleep and occasionally lead to a hard lockup. Therefore, post the create_ah and destroy_ah commands in polling mode if the RDMA_CREATE_AH_SLEEPABLE and RDMA_DESTROY_AH_SLEEPABLE flags are not set, respectively.

The commit 3ab1663af6c1 ("watchdog: stm32_iwdg: Add pretimeout support") introduces the support for the pre-timeout interrupt. The support for this interrupt is optional but the driver uses the platform_get_irq() which produces an error message during the driver probe if we don't have any `interrupts` property in the DT. Use the platform_get_irq_optional() API to get rid of the error message as this property is optional.

2024-12-30drm/mediatek: Fix mode valid issue for dpLiankun Yang
Fix dp mode valid issue to avoid abnormal display of limit state. After DP passes link training, it can express the lane count of the current link status is good. Calculate the maximum bandwidth supported by DP using the current lane count. The color format will select the best one based on the bandwidth requirements of the current timing mode. If the current timing mode uses RGB and meets the DP link bandwidth requirements, RGB will be used. If the timing mode uses RGB but does not meet the DP link bandwidthi requirements, it will continue to check whether YUV422 meets the DP link bandwidth. FEC overhead is approximately 2.4% from DP 1.4a spec 2.2.1.4.2. The down-spread amplitude shall either be disabled (0.0%) or up to 0.5% from 1.4a 3.5.2.6. Add up to approximately 3% total overhead.

2024-12-30platform/chrome: cros_ec: jump to RW before probingDawid Niedzwiecki
There are EC devices, like FPMCU, that use RWSIG as a method of authenticating RW section. After the authentication succeeds, EC device waits some time before jumping to RW. EC can be probed before the jump, which means there is a time window after jump to RW in which EC won't respond, because it is not initialized. It can cause a communication errors after probing. To avoid such problems, send the RWSIG continue command first, which skips waiting for the jump to RW. Send the command more times, to make sure EC is ready in RW before the start of the actual probing process. If a EC device doesn't support the RWSIG, it will respond with invalid command error code and probing will continue as usual.

The HP OMEN 8 (2022), corresponding to a board ID of 8A15, supports OMEN thermal profile and requires the timed profile quirk. Upon adding this ID to both the omen_thermal_profile_boards and omen_timed_thermal_profile_boards, significant bump in performance can be observed. For instance, SilverBench (https://silver.urih.com/) results improved from ~56,000 to ~69,000, as a result of higher power draws (and thus core frequencies) whilst under load: Package Power: - Before the patch: ~65W (dropping to about 55W under sustained load). - After the patch: ~115W (dropping to about 105W under sustained load). Core Power: - Before: ~60W (ditto above). - After: ~108W (ditto above). Add 8A15 to omen_thermal_profile_boards and omen_timed_thermal_profile_boards to improve performance.

2024-12-29virt: tdx-guest: Just leak decrypted memory on unrecoverable errorsLi RongQing
In CoCo VMs it is possible for the untrusted host to cause set_memory_decrypted() to fail such that an error is returned and the resulting memory is shared. Callers need to take care to handle these errors to avoid returning decrypted (shared) memory to the page allocator, which could lead to functional or security issues. Leak the decrypted memory when set_memory_decrypted() fails, and don't need to print an error since set_memory_decrypted() will call WARN_ONCE().
