Rebecca Cran 73b604bb1e OvmfPkg/Bhyve: Copy Real16ToFlat32.asm and enable cache in CR0 ... Copy UefiCpuPkg/ResetVector/Vtf0/Ia16/Real16ToFlat32.asm to OvmfPkg/Bhyve/ResetVector/Ia16, with one change, as has also been made in XenResetVector: - SEC_DEFAULT_CR0: enable cache (bit 30 or CD set to 0) With the CD bit set to 1, this has the downside on AMD systems of actually running with the cache disabled, which slows the entire system to a crawl. There's no need for this bit to be set in virtualized environments. This patch reapplies the change from the freebsd uefi-edk2 repo at 08c00f4e8d Signed-off-by: Rebecca Cran <rebecca@bsdio.com> Reviewed-by: Peter Grehan <grehan@freebsd.org> Acked-by: Laszlo Ersek <lersek@redhat.com> Message-Id: <20201124005733.18107-4-rebecca@bsdio.com>		2020-11-27 16:48:47 +00:00
