Subject: [PATCH] efi: new 'connectefi' command
|
|
|

When efi.quickboot is enabled on VMWare (which is the default for
|
|
|
|
hardware release 16 and later), it may happen that not all EFI devices
|
|
|
|
are connected. Due to this, browsing the devices in make_devices() just
|
|
|
|
fails to find devices, in particular disks or partitions for a given
|
|
|
|
disk.
|
|
|
|
This typically happens when network booting, then trying to chainload to
|
|
|
|
local disk (this is used in deployment tools such as Red Hat Satellite),
|
|
|
|
which is done through using the following grub.cfg snippet:
|
|
|
|
-------- 8< ---------------- 8< ---------------- 8< --------
|
|
|
|
unset prefix
|
|
|
|
search --file --set=prefix /EFI/redhat/grubx64.efi
|
|
|
|
if [ -n "$prefix" ]; then
|
|
|
|
chainloader ($prefix)/EFI/redhat/grubx64/efi
|
|
|
|
...
|
|
|
|
-------- 8< ---------------- 8< ---------------- 8< --------
|
|
|
|
|
|
|
|
With efi.quickboot, none of the devices are connected, causing "search"
|
|
|
|
to fail. Sometimes devices are connected but not the partition of the
|
|
|
|
disk matching $prefix, causing partition to not be found by
|
|
|
|
"chainloader".
|
|
|
|
|
|
|
|
This patch introduces a new "connectefi pciroot|scsi" command which
|
|
|
|
recursively connects all EFI devices starting from a given controller
|
|
|
|
type:
|
|
|
|
- if 'pciroot' is specified, recursion is performed for all PCI root
|
|
|
|
handles
|
|
|
|
- if 'scsi' is specified, recursion is performed for all SCSI I/O
|
|
|
|
handles (recommended usage to avoid connecting unwanted handles which
|
|
|
|
may impact Grub performances)
|
|
|
|
|
|
|
|
Typical grub.cfg snippet would then be:
|
|
|
|
-------- 8< ---------------- 8< ---------------- 8< --------
|
|
|
|
connectefi scsi
|
|
|
|
unset prefix
|
|
|
|
search --file --set=prefix /EFI/redhat/grubx64.efi
|
|
|
|
if [ -n "$prefix" ]; then
|
|
|
|
chainloader ($prefix)/EFI/redhat/grubx64/efi
|
|
|
|
...
|
|
|
|
-------- 8< ---------------- 8< ---------------- 8< --------
|
|
|
|
|
|
|
|
The code is easily extensible to handle other arguments in the future if
|
|
|
|
needed.
