[PATCH v4 0/4] Add support for zboot images compressed with zstd

Posted by Daan De Meyer 2 months, 2 weeks ago

Fedora arm64 has an EFI_ZBOOT kernel image compressed
with zstd. Let's make sure we can use it for direct kernel
boot with qemu.

Daan De Meyer (4):
  Rename LOAD_IMAGE_MAX_GUNZIP_BYTES to
    LOAD_IMAGE_MAX_DECOMPRESSED_BYTES
  Rename UBOOT_MAX_GUNZIP_BYTES to UBOOT_MAX_DECOMPRESSED_BYTES
  Use g_autofree in unpack_efi_zboot_image()
  Add support for zboot images compressed with zstd
