Subject: [PATCH] qemu: Add addition environment space to boot loader
|
qemu-system-mips
|
|
Upstream-Status: Inappropriate - OE uses deep paths
|
|
If you create a project with very long directory names like 128 characters
|
deep and use NFS, the kernel arguments will be truncated. The kernel will
|
accept longer strings such as 1024 bytes, but the qemu boot loader defaulted
|
to only 256 bytes. This patch expands the limit.
