-Subject: [PATCH] reopen SNP protocol for exclusive use by grub
-
-While working with pxeboot of grub on an ARM platform, I noticed
-very poor network performance while grub was loading a kernel
-and initramfs. The performance during the loading of grub itself
-seemed reasonable. Digging into the issue, I found that the UEFI
-firmware was periodically polling for network packets while grub
-was downloading files. This was causing timeouts and retries in
-the grub network stack.
-
-The solution I found was to reopen the SNP protocol for exclusive
-use. This forces UEFI to shutdown its use of SNP so that grub is
-not competing for incoming packets.
