[PATCH] drm/nouveau/gsp: Prepare fwsec-sb and fwsec-frts at boot

by Lyude Paul

At the moment - the memory allocations for fwsec-sb and fwsec-frts are created as needed and released after being used. This can cause runtime suspend/resume to initially work on driver load, but then later fail on a machine that has been running for long enough with sufficiently high enough memory pressure: kworker/7:1: page allocation failure: order:5, mode:0xcc0(GFP_KERNEL), nodemask=(null),cpuset=/,mems_allowed=0 CPU: 7 UID: 0 PID: 875159 Comm: kworker/7:1 Not tainted 6.17.8-300.fc43.x86_64 #1 PREEMPT(lazy) Hardware name: SLIMBOOK Executive/Executive, BIOS N.1.10GRU06 02/02/2024 Workqueue: pm pm_runtime_work Call Trace: <TASK> dump_stack_lvl+0x5d/0x80 warn_alloc+0x163/0x190 ? __alloc_pages_direct_compact+0x1b3/0x220 __alloc_pages_slowpath.constprop.0+0x57a/0xb10 __alloc_frozen_pages_noprof+0x334/0x350 __alloc_pages_noprof+0xe/0x20 __dma_direct_alloc_pages.isra.0+0x1eb/0x330 dma_direct_alloc_pages+0x3c/0x190 dma_alloc_pages+0x29/0x130 nvkm_firmware_ctor+0x1ae/0x280 [nouveau] nvkm_falcon_fw_ctor+0x3e/0x60 [nouveau] nvkm_gsp_fwsec+0x10e/0x2c0 [nouveau] ? sysvec_apic_timer_interrupt+0xe/0x90 nvkm_gsp_fwsec_sb+0x27/0x70 [nouveau] tu102_gsp_fini+0x65/0x110 [nouveau] ? ktime_get+0x3c/0xf0 nvkm_subdev_fini+0x67/0xc0 [nouveau] nvkm_device_fini+0x94/0x140 [nouveau] nvkm_udevice_fini+0x50/0x70 [nouveau] nvkm_object_fini+0xb1/0x140 [nouveau] nvkm_object_fini+0x70/0x140 [nouveau] ? __pfx_pci_pm_runtime_suspend+0x10/0x10 nouveau_do_suspend+0xe4/0x170 [nouveau] nouveau_pmops_runtime_suspend+0x3e/0xb0 [nouveau] pci_pm_runtime_suspend+0x67/0x1a0 ? __pfx_pci_pm_runtime_suspend+0x10/0x10 __rpm_callback+0x45/0x1f0 ? __pfx_pci_pm_runtime_suspend+0x10/0x10 rpm_callback+0x6d/0x80 rpm_suspend+0xe5/0x5e0 ? finish_task_switch.isra.0+0x99/0x2c0 pm_runtime_work+0x98/0xb0 process_one_work+0x18f/0x350 worker_thread+0x25a/0x3a0 ? __pfx_worker_thread+0x10/0x10 kthread+0xf9/0x240 ? __pfx_kthread+0x10/0x10 ? __pfx_kthread+0x10/0x10 ret_from_fork+0xf1/0x110 ? __pfx_kthread+0x10/0x10 ret_from_fork_asm+0x1a/0x30 </TASK> The reason this happens is because the fwsec-sb and fwsec-frts firmware images only support being booted from a contiguous coherent sysmem allocation. If a system runs into enough memory fragmentation from memory pressure, such as what can happen on systems with low amounts of memory, this can lead to a situation where it later becomes impossible to find space for a large enough contiguous allocation to hold each firmware image. As such, we fail to allocate memory for the falcon firmware images - fail to boot the GPU, and the driver falls over. Since this firmware can't use non-contiguous allocations, the best solution to avoid this issue is to simply allocate the memory for both fwsec-sb and fwsec-frts during initial driver load, and reuse said allocations whenever either firmware image needs to be used. We then release the memory allocations on driver unload.

[PATCH v1] Revert "drm: bridge: ti-sn65dsi83: Add error recovery mechanism"

by Francesco Dolcini

From: Francesco Dolcini <francesco.dolcini(a)toradex.com> This reverts commit ad5c6ecef27e ("drm: bridge: ti-sn65dsi83: Add error recovery mechanism"). The reverted commit introduces a regression on Verdin AM62, and potentially on more devices, not being able to generate a clock that the TI SN65DSI83 PLL can lock to, with the display periodically blinking. Verdin AM62 SoM has a Toshiba TC358778 DPI to DSI bridge, that can be connected to an LVDS display over a TI SN65DSI83 bridge. Before this change despite the TI SN65DSI83 reporting with a debug print a PLL locking error the display was working fine with no visible glitches. The reasons for this issue was investigated without getting to a final conclusion: - the DPI clock was measure and it is stable/accurate - the DSI clock was not possible to measure, but this setup is used with other display/bridges with no known issues - the DSI clock is configured in continuous mode - the actual DSI clock generated from the TC358778 is generate with a PLL from a 25MHz reference clock - it's not clear why some frequencies are working and some are not, for example 50000000, 68750000, 72750000, 75000000 frequencies are fine, while 69750000, 71100000, 72500000 are not Given that the safest approach is to just revert the commit, till a proper solution for error recovery that is not introducing regression is figured out.

A VDEV_PORT_ERROR flag is used to track this state, preventing new transfers from being queued until error is cleared.

A VDEV_PORT_ERROR flag is used to track this state, preventing new transfers from being queued until error is cleared. This flag may be left uncleared if link goes to error state between two resets, and print the following message: "xhci_hcd 0000:00:14.0: Can't queue urb, port error, link inactive" Fix setting and clearing the flag. The flag is cleared after hub driver has successfully reset the device when hcd->reset_device is called. xhci-hcd issues an internal "reset device" command in this callback, and clear all flags once the command completes successfully. This command may complete with a context state error if slot was recently reset and is already in the defauilt state. This is treated as a success but flag was left uncleared.

[PATCH] tpm2-sessions: Fix tpm2_read_public range checks

by Jarkko Sakkinen

'tpm2_read_public' has some rudimentary range checks but does not explicitly check that both fields of TPMT_HA actually fit within the buffer size limits. Introduce a new function 'tpm2_resolve_name' to address all the possible out-of-range issues, and in addition do handle type validation.

Avoids OOB access in fbcon_remap_all(). Without holding the console lock the call races with switching outputs. VGA switcheroo calls fbcon_remap_all() when switching clients. The fbcon function uses struct fb_info.node, which is set by register_framebuffer(). As the fb-helper code currently sets up VGA switcheroo before registering the framebuffer, the value of node is -1 and therefore not a legal value. For example, fbcon uses the value within set_con2fb_map() [1] as an index into an array. Moving vga_switcheroo_client_fb_set() after register_framebuffer() can result in VGA switching that does not switch fbcon correctly.

Although vga_switcheroo_client_fb_set() takes an instance of struct fb_info as parameter, it really only needs the contained fbcon state.

On R-Car Gen4 and RZ/G3E SoCs, due to the wrong logic in the commit[1] sets the default mode to FD-Only mode instead of CAN-FD mode. This patch sets the CAN-FD mode as the default for all SoCs by dropping the rcar_canfd_set_mode() as some SoC requires mode setting in global reset mode, and the rest of the SoCs in channel reset mode and update the rcar_canfd_reset_controller() to take care of these constraints. Moreover, the RZ/G3E and R-Car Gen4 SoCs support 3 modes compared to 2 modes on the R-Car Gen3. Use inverted logic in rcar_canfd_reset_controller() to simplify the code later to support FD-only mode.

Backport d2099d9f16db ("net/mlx5e: Fix validation logic in rate limiting") to linux-6.12.y

by Simon Liebold

Hi, I see that a backport of commit [1] has been merged into the 6.12 LTS tree as part of v6.12.59. I suggest commit [2] to be backported to linux-6.12.y too since it's a follow up fix for [1]. [1] 43b27d1bd88a ("net/mlx5e: Fix wraparound in rate limiting for values above 255 Gbps") [2] d2099d9f16db ("net/mlx5e: Fix validation logic in rate limiting") I tested the change and everything looks good. It's a clean cherry-pick.

[PATCH] wifi: ath12k: correctly handle mcast packets for clients

by Oliver Sedlbauer

From: Sarika Sharma <quic_sarishar(a)quicinc.com> [ Upstream commit 4541b0c8c3c1b85564971d497224e57cf8076a02 ] Currently, RX is_mcbc bit is set for packets sent from client as destination address (DA) is multicast/broadcast address, but packets are actually unicast as receiver address (RA) is not multicast address. Hence, packets are not handled properly due to this is_mcbc bit. Therefore, reset the is_mcbc bit if interface type is AP. Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00199-QCAHKSWPL_SILICONZ-1 Signed-off-by: Sarika Sharma <quic_sarishar(a)quicinc.com> Reviewed-by: Vasanthakumar Thiagarajan <vasanthakumar.thiagarajan(a)oss.qualcomm.com> Link: https://patch.msgid.link/20250411061523.859387-3-quic_sarishar@quicinc.com Signed-off-by: Jeff Johnson <jeff.johnson(a)oss.qualcomm.com> [ Adjust context ] Signed-off-by: Oliver Sedlbauer <os(a)dev.tdt.de> --- Context: The issue was introduced in 6.12.y by the backport of commit f66971c608c4 ("wifi: ath12k: using msdu end descriptor to check for rx multicast packets"), which was part of a patchset: https://lore.kernel.org/all/20250411061523.859387-1-quic_sarishar@quicinc.c… That commit, without this follow-up patch, causes mac80211 to drop encrypted ARP request frames. As a result, ARP resolution fails, and connectivity from a station to an AP does not work reliably until traffic is initiated by the AP. This follow-up commit is necessary to restore correct network functionality for ath12k clients on 6.12.y. Note: The patch has been modified to apply cleanly, including adjustments for API changes.
