Title:
linux-raspi2: rebase the Eoan kernel to the latest rpi-5.3.y branch
(2a085c9b42ea)
Status in linux-raspi2 package in Ubuntu:
Confirmed
Status in linux-raspi2 source package in Eoan:
Fix Released
Bug description:
[Impact]
https://bugs.launchpad.net/bugs/1848790
https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1848703
Recently we had 2 bugs about the usb host on rpi4 with 4G ram, and I found
the kernel in the github already had the fix for this issue, and besides this
fix, it also had 106 more patches than our eoan kernel, those patches were
merged during or after we prepared our eoan kernel, now let us pick those
patches to our eoan too.
[Fix]
For the usb host issue, it adds a fix by setting the usb dma bounce buffer
under 1G.
[Test Case]
some users and I alreaady tested the armhf and arm64 kernel on pi4 and pi3
boards, the usb host worked well and no other regressions introduced.
[Regression Risk]
Low, these patches are from the github which is the pi official kernel
repository. And we already tested armhf and arm64 kernel on pi4/3 boards.
The rpi kernel of https://github.com/raspberrypi/linux.git has been
updated, for the branch of rpi-5.3.y (Eoan kernel base on this
branch), there are 107 new patches merged, we also need to merge those
patches to Eoan kernel.
