[edk2-devel] [PATCH 14/43] OvmfPkg/XenAcpiPlatformDxe: remove QEMU fw_cfg dependency
Laszlo Ersek
lersek at redhat.com
Wed May 26 20:14:17 UTC 2021
The QemuDetected() function wraps QemuFwCfgIsAvailable(); it always fails
on Xen. Because of that, we can eliminate the QemuDetected() call itself
from the Xen ACPI platform driver, and then the rest of "Qemu.c" becomes
useless -- the workhorse function of that source file is
QemuInstallAcpiTable(), which we no longer call.
Remove any dependencies that are no longer needed by the
XenAcpiPlatformDxe driver.
