Emit a DEBUG_WARN message if there is not enough flash space left to write/update a variable. This condition is currently not logged appropriately in all cases, given that full variable store can easily render the system unbootable. This new message helps identifying this condition quickly.
Launching OVMF with a full variable store then looks like this (Debug Output): [...] CommonVariableSpace = 0x3FF9C - CommonVariableTotalSize = 0x3FF60 UpdateVariable failed: Out of flash space Select Item: 0xE Select Item: 0x19 RecordVarErrorFlag (0xEF) Timeout:8BE4DF61-93CA-11D2-AA0D-00E098032B8C - 0x00000007 - 0x4E CommonVariableSpace = 0x3FF9C - CommonVariableTotalSize = 0x3FF60 UpdateVariable failed: Out of flash space PlatformBootManagerBeforeConsole: SetVariable(Timeout, 3): Out of Resources RecordVarErrorFlag (0xEF) BootOrder:8BE4DF61-93CA-11D2-AA0D-00E098032B8C - 0x00000007 - 0x52 CommonVariableSpace = 0x3FF9C - CommonVariableTotalSize = 0x3FF60 UpdateVariable failed: Out of flash space ASSERT_EFI_ERROR (Status = Out of Resources) ASSERT /home/osteffen/work/firmware/edk2/edk2/edk2/OvmfPkg/Library/PlatformBootManagerLib/BdsPlatform.c(361): !(((INTN)(RETURN_STATUS)(Status)) < 0) PR: https://github.com/tianocore/edk2/pull/5435 Cc: Bob Feng <bob.c.f...@intel.com> Cc: Gerd Hoffmann <kra...@redhat.com> Cc: Laszlo Ersek <ler...@redhat.com> Cc: Liming Gao <gaolim...@byosoft.com.cn> Cc: Rebecca Cran <rebe...@bsdio.com> Cc: Yuwei Chen <yuwei.c...@intel.com> Oliver Steffen (1): MdeModulePkg: Warn if out of flash space when writing variables MdeModulePkg/Universal/Variable/RuntimeDxe/Variable.c | 2 ++ 1 file changed, 2 insertions(+) -- 2.44.0 -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
