[Bug 2142298] Re: [FFe] Add ability to change UMA carveout BIOS setting

[Launchpad Bug Tracker]

This bug was fixed in the package fwupd - 2.0.20-1ubuntu1

---------------
fwupd (2.0.20-1ubuntu1) resolute; urgency=low

  * Enable UMA carveout feature (LP: #2142298)
  * Merge from Debian unstable. Remaining changes:
    - d/p/db-update-snapd-bad-request.patch: On TPM/FDE systems, db updates
      require notifying snapd for preparation. However, the payload uses an
      incorrect format for composite updates. Change the format to align
      with snapd.
    - d/p/fwupdmgr-fde-verify-snapd-recovery-key.patch: Make fwupdmgr
      verify snapd recovery key through prompt on updates affecting FDE.

Title:
  [FFe] Add ability to change UMA carveout BIOS setting

Status in fwupd package in Ubuntu:
  Fix Released

Bug description:
  A new feature coming to kernel 7.0 is the ability to change the amount
  of UMA carveout on AMD systems that is programmed in the BIOS.

  https://docs.kernel.org/next/gpu/amdgpu/driver-misc.html#uma-carveout

  This feature requires a privileged process to write the value.  To
  wrap up the interface with policy kit it is being brought into fwupd.

  https://github.com/fwupd/fwupd/pull/9925

  I'm still working on the code review upstream, but I'm expecting we
  can merge this upstream and bring it to the stable branch that Ubuntu
  26.04 tracks.
