# Test Case: FreeBSD 15 Local Vnode Pager
|
|
|
|
**Test ID**: TC064-vop-getpages-normal
|
|
**Category**: VM Integration
|
|
**Priority**: Critical
|
|
|
|
## Objective
|
|
|
|
Verify the exact KLD resolves FreeBSD 15 local pager entry points and real
|
|
plain/LZ4 vnode mappings fault data through the pager.
|
|
|
|
## Procedure
|
|
|
|
Record unresolved KLD symbols with nm -u. On separate fresh mounts of
|
|
vfs/vfs-plain.erofs and vfs/vfs-lz4.erofs, run:
|
|
|
|
./mmap_fault /tmp/repo22-g3/mnt/pager.bin
|
|
|
|
## Expected Results
|
|
|
|
The KLD loads with vnode_pager_local_getpages and
|
|
vnode_pager_local_getpages_async resolved. Both helpers report identical
|
|
21211-byte FNV hashes, six random faults, partial-EOF zeroing, expected child
|
|
SIGBUS, denied writable shared mapping, private COW, and O_RDWR EROFS. Record
|
|
both image hashes, dmesg, and per-mount cleanup.
