kernel: Fix FIFO table fortify_panic + GSP boot-state reset on queue death + ISO fbRegion
- gsp_rm_handle_fifo_device_table: read baseIndex from the queue element
buffer (req_data + hdr), not past the local 24-byte header struct -
FORTIFY proved the old memcpy always overflows -> fortify_panic killed
gsp_emu_0 mid RmInitNvDevice (guest timed out on fn 76).
- gsp_emu_clear_boot_state: clear WPR2/RISCV/mailboxes/stage tracker and
reset GSP-RM queue state. Turing guests produce no observable BAR0
writes on unload, so the next probe's _kgspBootGspRm failed with
'unexpected WPR2 already up'. Trigger on ENGINE reset and on detected
queue death (insane writePtr jump / garbage element signature).
- GspStaticConfigInfo fbRegion[0].supportISO=1: memmgrCalcReservedFbSpace
asserts some region supports ISO 'even with no display'; without it
kdispStateInitLocked couldn't allocate clientChannelTable.
- .gitignore: scripts/git-push-vgpu.sh (local per-machine helper)
