[Bug 2141377] Re: [SRU]Fix xe GPU suspend/resume crash on Battlemage

This bug is awaiting verification that the linux-oem-6.17/6.17.0-1013.13
kernel in -proposed solves the problem. Please test the kernel and
update this bug with the results. If the problem is solved, change the
tag 'verification-needed-noble-linux-oem-6.17' to 'verification-done-
noble-linux-oem-6.17'. If the problem still exists, change the tag
'verification-needed-noble-linux-oem-6.17' to 'verification-failed-
noble-linux-oem-6.17'.


If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.


See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Bug description:
[ Impact ]
Intel Battlemage xe GPU (8086:e212) crashes during system resume with
NULL pointer dereference in xe_guc_ads_populate_post_load(), making
suspend/resume non-functional on affected systems.

Root cause: Noble 6.17 kernels have commit 59cebf0bdff48 but are missing
its prerequisite commit 1313351e71181. Without proper forcewake handling,
MMIO register access causes hardware corruption.

[ Fix ]
Cherry-pick upstream commit from v6.18-rc1:
- 1313351e71181 ("drm/xe: make xe_gt_idle_disable_c6() handle the forcewake internally")

[ Test Plan ]
1. System: Lenovo ThinkStation P3 Ultra G2 with Battlemage dGPU (8086:e212)
2. Reproduce: rtcwake -m mem -s 10
3. Verify: System resumes successfully without crashes

[ Where problems could occur ]
It may break xe driver GT idle/power management, affects suspend/resume path. Commit is from mainline v6.18-rc1.

The dGPU is not fully certified on v6.8 kernel, so SRU for questing
and oem-6.17.

Title:
Regression: ip route get intermittently returns broadcast …
<local,brd> for public IPs on 6.8.0-100 (breaks outbound TCP/Docker
pulls)

Status in linux package in Ubuntu:
Confirmed

Bug description:
Summary / Regression
This is a regression between Ubuntu kernels on an Ubuntu VM (Proxmox/QEMU/KVM, bridged networking, DHCP reservation). With 6.8.0-100-generic, ip -details route get <public-ip> intermittently returns an invalid cached result marking public IPs as broadcast/local (cache <local,brd>). When it enters this state, outbound TCP fails with "Network is unreachable" and Docker/Portainer pulls fail. Booting 6.8.0-90-generic on the same VM fixes it (route lookups remain unicast).

Environment

Ubuntu VM on Proxmox VE (QEMU/KVM), bridge vmbr0, DHCP reservation.

Reproduced across configuration changes: virtio/e1000 NIC, cpu
host/kvm64, cloud-init disabled; persists specifically with 6.8.0-100
and disappears with 6.8.0-90.

Evidence (6.8.0-100-generic)
Running repeatedly:
ip -details route get 1.1.1.1
shows flapping between correct unicast and incorrect broadcast classification:

unicast 1.1.1.1 via 192.168.1.1 dev ens18 table main src 192.168.1.72
cache
broadcast 1.1.1.1 via 192.168.1.1 dev ens18 table main src 192.168.1.72
cache <local,brd>
broadcast 1.1.1.1 via 192.168.1.1 dev ens18 table main src 192.168.1.72
cache <local,brd>

When the broadcast … <local,brd> state appears, outbound TCP
connections to public IPs fail ("Network is unreachable"), and ubuntu-
bug linux upload also sometimes fails with urlopen error [Errno 101]
Network is unreachable.

Expected
Public IPs should never be classified as broadcast … <local,brd> in route lookup; outbound TCP should stay stable.

Workaround
Boot kernel 6.8.0-90-generic (issue disappears). Flushing caches (ip route flush cache and ip neigh flush dev ens18) temporarily restores correct behavior on 6.8.0-100.

  * b1dcec9bd8a1d drm/xe/ptl: Enable PXP for PTL
  * 6d24027d555e4 drm/xe/ptl: Define GSC for PTL
  * 65b65ffcf669c drm/xe/gsc: Make GSC FW load optional for newer platforms
* firmware: (main branch only)
  * 05a6a40bb xe: Add GSC 105.0.2.1301 for PTL

[Test Plan]

With GSC firmware loaded:
```
$ sudo dmesg|grep -i gsc
[ 6.925262] xe 0000:00:02.0: [drm] GT1: Using GSC firmware from xe/ptl_gsc_1.bin version 105.0.2.1301

[ 7.097263] xe 0000:00:02.0: [drm] GT1: found GSC cv105.1.0
```

[Where problems could occur]

Opaque firmware. Expect maybe stability updates.

[Other Info]

While PTL was scheduled for v6.17 kernels, nominate fix for R, Q and
linux-oem-6.17/noble.

========== original bug report ==========

On newer platforms GSC FW is only required for content protection
features, so the core driver features work perfectly fine without it.
GSC was previously made optional for PTL.

Bug description:
SRU Justification:

[ Impact ]

Intel E810 network adapters experience kernel NULL pointer dereference
crashes during system resume when PTP is enabled. This occurs due to a
race condition where PTP periodic work attempts to access vsi->rx_rings
while VSI structures are being rebuilt, causing system instability and
potential data loss during suspend/resume cycles.

The crash occurs in this sequence:
1. System suspend triggers ice_ptp_prepare_for_reset() which cancels PTP work
2. ice_ptp_rebuild() immediately queues PTP work before VSI rebuild
3. PTP work executes and accesses NULL vsi->rx_rings
4. System crashes with NULL pointer dereference

[ Fix ]

Cherry-pick upstream commit:
- 8be3a229a6112 ("ice: Fix PTP NULL pointer dereference during VSI rebuild")
from https://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue.git dev-queue

The fix keeps PTP work cancelled during rebuild and only queues it after
VSI rebuild completes. Adds ice_ptp_queue_work() helper function to
encapsulate proper timing of PTP work queue.

[ Test Plan ]

1. System with Intel E810 network adapter (ice driver)
2. Enable PTP: ptp4l -i <interface> -m
3. Suspend system: systemctl suspend
4. Resume system
5. Verify no kernel crash in dmesg (check for NULL pointer dereference in ice_ptp_update_cached_phctime)
6. Verify network connectivity restored: ping <target>
7. Verify PTP synchronization working: ptp4l shows proper sync
8. Repeat suspend/resume cycle multiple times to ensure stability

[ Where problems could occur ]

The patch changes when PTP work is queued during VSI rebuild. If there's
an error in the timing logic, PTP synchronization might be delayed after
resume, though the delay would be minimal (sub-second).

Risk is very low because:
- The fix only affects the suspend/resume path, not normal operation
- PTP work is still queued, just at the correct time (after VSI rebuild)
- The helper function includes proper state checking (ICE_PTP_READY)
- Change is isolated to PTP subsystem

[ Other Info ]

This issue affects systems using Intel E810 NICs with PTP enabled,
particularly in environments requiring frequent suspend/resume cycles
(laptops, power-managed servers).

The upstream commit is in the Intel Wired LAN maintainer's tree
(next-queue) and expected to be merged to mainline in the next cycle.
