Text mode VGA-console scrolling is broken in upstream & stable trees

by Jari Ruusu

The patch that broke text mode VGA-console scrolling is this one: "vgacon: Add check for vc_origin address range in vgacon_scroll()" commit 864f9963ec6b4b76d104d595ba28110b87158003 upstream. How to preproduce: (1) boot a kernel that is configured to use text mode VGA-console (2) type commands: ls -l /usr/bin | less -S (3) scroll up/down with cursor-down/up keys Above mentioned patch seems to have landed in upstream and all kernel.org stable trees with zero testing. Even minimal testing would have shown that it breaks text mode VGA-console scrolling. Greg, Sasha, Linus, Please consider reverting that buggy patch from all affected trees. -- Jari Ruusu 4096R/8132F189 12D6 4C3A DCDA 0AA4 27BD ACDF F073 3C80 8132 F189

[PATCH 0/5] drm/i915: fixes for i915 Hot Plug Detection and build/runtime issues

by Nicusor Huhulea

Hello maintainers, This series addresses a defect observed on certain hardware platforms using Linux kernel 6.1.147 with the i915 driver. The issue concerns hot plug detection (HPD) logic, leading to unreliable or missed detection events on affected hardware. This is happening on some specific devices. ### Background Issue: On Simatic IPC227E, we observed unreliable or missing hot plug detection events, while on Simatic IPC227G (otherwise similar platform), expected hot plug behavior was maintained. Affected kernel: This patch series is intended for the Linux 6.1.y stable tree only (tested on 6.1.147) Most of the tests were conducted on 6.1.147 (manual/standalone kernel build, CIP/Isar context). Root cause analysis: I do not have access to hardware signal traces or scope data to conclusively prove the root cause at electrical level. My understanding is based on observed driver behavior and logs. Therefore my assumption as to the real cause is that on IPC227G, HPD IRQ storms are apparently not occurring, so the standard HPD IRQ-based detection works as expected. On IPC227E, frequent HPD interrupts trigger the i915 driver’s storm detection logic, causing it to switch to polling mode. Therefore polling does not resume correctly, leading to the hotplug issue this series addresses. Device IPC227E's behavior triggers this kernel edge case, likely due to slight variations in signal integrity, electrical margins, or internal component timing. Device IPC227G, functions as expected, possibly due to cleaner electrical signaling or more optimal timing characteristics, thus avoiding the triggering condition. Conclusion: This points to a hardware-software interaction where kernel code assumes nicer signaling or margins than IPC227E is able to provide, exposing logic gaps not visible on more robust hardware. ### Patches Patches 1-4: - Partial backports of upstream commits; only the relevant logic or fixes are applied, with other code omitted due to downstream divergence. - Applied minimal merging without exhaustive backport of all intermediate upstream changes. Patch 5: - Contains cherry-picked logic plus context/compatibility amendments as needed. Ensures that the driver builds. - Together these fixes greatly improve reliability of hotplug detection on both devices, with no regression detected in our setups. Thank you for your review, Nicusor Huhulea This patch series contains the following changes: Dmitry Baryshkov (2): drm/probe_helper: extract two helper functions drm/probe-helper: enable and disable HPD on connectors Imre Deak (2): drm/i915: Fix HPD polling, reenabling the output poll work as needed drm: Add an HPD poll helper to reschedule the poll work Nicusor Huhulea (1): drm/i915: fixes for i915 Hot Plug Detection and build/runtime issues drivers/gpu/drm/drm_probe_helper.c | 127 ++++++++++++++----- drivers/gpu/drm/i915/display/intel_hotplug.c | 4 +- include/drm/drm_modeset_helper_vtables.h | 22 ++++ include/drm/drm_probe_helper.h | 1 + 4 files changed, 122 insertions(+), 32 deletions(-) -- 2.39.2

[PATCH 1/2] tpm: Compare HMAC values in constant time

[PATCH net v2] net: usbnet: Avoid potential RCU stall on LINK_CHANGE event

by John Ernberg

The Gemalto Cinterion PLS83-W modem (cdc_ether) is emitting confusing link up and down events when the WWAN interface is activated on the modem-side. Interrupt URBs will in consecutive polls grab: * Link Connected * Link Disconnected * Link Connected Where the last Connected is then a stable link state. When the system is under load this may cause the unlink_urbs() work in __handle_link_change() to not complete before the next usbnet_link_change() call turns the carrier on again, allowing rx_submit() to queue new SKBs. In that event the URB queue is filled faster than it can drain, ending up in a RCU stall: rcu: INFO: rcu_sched detected expedited stalls on CPUs/tasks: { 0-.... } 33108 jiffies s: 201 root: 0x1/. rcu: blocking rcu_node structures (internal RCU debug): Sending NMI from CPU 1 to CPUs 0: NMI backtrace for cpu 0 Call trace: arch_local_irq_enable+0x4/0x8 local_bh_enable+0x18/0x20 __netdev_alloc_skb+0x18c/0x1cc rx_submit+0x68/0x1f8 [usbnet] rx_alloc_submit+0x4c/0x74 [usbnet] usbnet_bh+0x1d8/0x218 [usbnet] usbnet_bh_tasklet+0x10/0x18 [usbnet] tasklet_action_common+0xa8/0x110 tasklet_action+0x2c/0x34 handle_softirqs+0x2cc/0x3a0 __do_softirq+0x10/0x18 ____do_softirq+0xc/0x14 call_on_irq_stack+0x24/0x34 do_softirq_own_stack+0x18/0x20 __irq_exit_rcu+0xa8/0xb8 irq_exit_rcu+0xc/0x30 el1_interrupt+0x34/0x48 el1h_64_irq_handler+0x14/0x1c el1h_64_irq+0x68/0x6c _raw_spin_unlock_irqrestore+0x38/0x48 xhci_urb_dequeue+0x1ac/0x45c [xhci_hcd] unlink1+0xd4/0xdc [usbcore] usb_hcd_unlink_urb+0x70/0xb0 [usbcore] usb_unlink_urb+0x24/0x44 [usbcore] unlink_urbs.constprop.0.isra.0+0x64/0xa8 [usbnet] __handle_link_change+0x34/0x70 [usbnet] usbnet_deferred_kevent+0x1c0/0x320 [usbnet] process_scheduled_works+0x2d0/0x48c worker_thread+0x150/0x1dc kthread+0xd8/0xe8 ret_from_fork+0x10/0x20 Get around the problem by delaying the carrier on to the scheduled work.
