Subject: net: cpsw_new: Execute ndo_set_rx_mode callback in a work queue
Date: Wed, 4 Feb 2026 14:27:57 +0800
commit c0b5dc73a38f954e780f93a549b8fe225235c07a from net
Commit 1767bb2d47b7 ("ipv6: mcast: Don't hold RTNL for
IPV6_ADD_MEMBERSHIP and MCAST_JOIN_GROUP.") removed the RTNL lock for
IPV6_ADD_MEMBERSHIP and MCAST_JOIN_GROUP operations. However, this
change triggered the following call trace on my BeagleBone Black board:
WARNING: net/8021q/vlan_core.c:236 at vlan_for_each+0x120/0x124, CPU#0:

This trace occurs because vlan_for_each() is called within
cpsw_ndo_set_rx_mode(), which expects the RTNL lock to be held.
Since modifying vlan_for_each() to operate without the RTNL lock is not
straightforward, and because ndo_set_rx_mode() is invoked both with and
without the RTNL lock across different code paths, simply adding
rtnl_lock() in cpsw_ndo_set_rx_mode() is not a viable solution.
To resolve this issue, we opt to execute the actual processing within
a work queue, following the approach used by the icssg-prueth driver.
Fixes: 1767bb2d47b7 ("ipv6: mcast: Don't hold RTNL for IPV6_ADD_MEMBERSHIP
and MCAST_JOIN_GROUP.")

Subject: drm/tilcdc: Set preferred depth
Date: Wed, 4 Feb 2026 14:27:58 +0800
The commit c91acda3a380 ("drm/gem: Check for valid formats") adds a
check for valid pixel formats on drm_gem_fb_create(), but this breaks
the X server on the beaglebone black board.
We have set 'DefaultDepth' to 16 in our xorg.conf. In the X modesetting
driver, the drmmode_get_default_bpp() is used to guess the default
depth/bpp. First it tries to get them via DRM_CAP_DUMB_PREFERRED_DEPTH
ioctl, and if it fail, then try to create a FB with 'depth = 24' and
'bpp = 32' to check whether this depth/dpp is a valid combo. Before the
kernel commit c91acda3a380, the FB always can be created successfully.
This will avoid the bpp to be set to 24 forcibly. But after kernel
commit c91acda3a380, the FB will not be created successfully due to the
check of the valid pixel format. Then the bpp is set to 24, but the
'depth = 16' and 'bpp = 24' combo is not a valid pixel format.
Fix this issue by explicitly setting the preferred_depth in this driver.
With this change, the modesetting driver would choose the correct
depth/bpp combo based on our setting in xorg.conf.
