* feat: add GPU fields to NodeStatus and spx top nodes (mulga-996)
- Add TotalGPUs/AllocGPUs to NodeStatusResponse (zero on non-GPU nodes)
- Populate from gpuManager in handleNodeStatus
- Show GPU (used/total) column in spx top nodes; "-" when no GPUs present
* Fixed GPU passthrough and added test script
* feat: always-probe GPU at startup, surface capability in NodeStatusResponse
- Add gpuProbeResult struct and probeGPU() which runs at daemon startup
regardless of gpu_passthrough config. Checks sysfs for GPUs, IOMMU
groups, and vfio_pci module presence.
- Store gpuProbe on Daemon struct; split NewDaemon into probe (always)
and activate (opt-in) phases.
- Populate GPUCapable, GPUPassthrough, GPUModels on NodeStatusResponse
so operators can see hardware state before enabling passthrough.
- Update 'spx top' GPU column: '-' = no hardware, '0/N*' = capable but
passthrough not active, 'used/total' = passthrough active.
* feat: SIGHUP hot-reload for GPU passthrough config (mulga-1001)
- Export GenerateGPUTypes for use by the reload path
- Add ResourceManager.reloadGPUTypes: mutates instanceTypes map in-place
(preserves references held by instanceService) and updates NATS
subscriptions without full daemon restart
- Separate SIGHUP from SIGTERM/SIGINT: setupReload() listens for SIGHUP
in a context-aware loop; setupShutdown no longer intercepts SIGHUP
- Add reloadConfig() + applyGPUConfig(): re-reads spinifex.toml on signal,
handles false→true (re-probe + activate) and true→false (refuse if
instances running, otherwise deactivate) transitions

* feat: multi-GPU passthrough support for g7e.12xlarge (2× MI350X)
- vm.VM: GPUPCIAddress string → GPUPCIAddresses []string for multi-GPU
- instancetypes: add g7e.12xlarge (2 GPUs), GPUCountForType(), AMDmi350x model
- instancetypes/generate: use GPUCountForType for GpuInfo.Count and TotalGpuMemoryInMiB
- gpu/manager: Release() loops all pool entries for instanceID (not just first)
- vm/lifecycle: loop over GPUPCIAddresses, emit gpu0/gpu1/... QEMU devices
- daemon/handlers: claim N GPUs in loop for both RunInstances and StartStoppedInstance
- daemon/vm_adapters: ReclaimByAddress loops GPUPCIAddresses; ReleaseGPU checks len > 0
- scripts/launch-gpu-fleet: fixed fleet — 6× g7e.4xlarge + 1× g7e.12xlarge
* feat: per-instance-type disk size in GPU fleet (300 GB single, 600 GB dual)
* fix: multi-gpu instance types
* fix: kill QEMU synchronously when QMP handshake fails to free VFIO device
When startQEMU succeeds but newQMPClientWithHandshake times out, the
instance has not yet been inserted into the manager map so vmMgr.Delete
in the rollback path is a no-op. QEMU keeps running and holds the VFIO
group open. The GPU pool entry gets freed, the next Claim returns the
same PCI address, and every subsequent QEMU fails with 'device or
resource busy'.
Fix: SIGKILL QEMU and wait for it to exit before returning the QMP
error, ensuring the VFIO device is released before the caller recycles
the GPU pool slot.
* fix: quarantine GPU after QEMU launch failure to prevent re-assignment cascade
When QEMU crashes during startup (e.g. pci_irq_handler assertion on a
specific GPU), the pool Release frees that address and the next NATS
request immediately re-claims the same broken device. Add MarkFailed()
to gpu.Manager which sets Available=false for a PCI address after a
launch failure, preventing re-assignment until the daemon restarts.
Call MarkFailed for each GPU address in both RunInstances and
StartStoppedInstance rollback paths after the Release succeeds.

* feat: add GPU discovery package (mulga-992)
Adds spinifex/gpu package with sysfs-based GPU enumeration, IOMMU group
member lookup, and a PCI device ID model table. Vendor-specific enrichment
via nvidia-smi is attempted opportunistically and falls back to the built-in
table when unavailable. All discovery and IOMMU logic is covered by unit tests
using mock sysfs trees.
* feat: add VFIO bind/unbind and GPU pool manager (mulga-993)
Adds gpu.BindVFIO/UnbindVFIO using sysfs driver_override for per-device
driver switching, and gpu.Manager which owns the claim/release lifecycle
for the GPU pool including full IOMMU group binding, rollback on partial
failure, and marking entries unavailable when rebind fails after VM
termination.
* feat: add G5 instance type generator with GPU model support (mulga-994)
- Add GPUModel type, NVIDIAa10g constant, and GPUModelForVendorDevice lookup
- Add generateGPUTypes to emit g5.* types with GpuInfo populated
- Add IsGPUType helper for consumers filtering GPU-capable types
- Update DetectAndGenerate to accept gpuModels []GPUModel parameter
* feat: integrate GPU passthrough into daemon lifecycle (mulga-995)
- Add gpu_passthrough config flag; discover GPUs and build manager at startup
- Gate g5 instance types on GPU pool availability via canAllocateCount
- Claim GPU (VFIO bind) in LaunchInstance; inject vfio-pci QEMU device
- Release GPU (VFIO unbind, rebind to host driver) in stopInstance
- Re-claim GPU on daemon restart when QEMU process is still alive
- Add UseUEFI / OVMF support for x86_64 VMs (optional, falls back to SeaBIOS)
- Fix Claim to use stored OriginalDriver when device is already vfio-pci bound
* feat: add GPU fields to NodeStatus and spx top nodes (mulga-996)
- Add TotalGPUs/AllocGPUs to NodeStatusResponse (zero on non-GPU nodes)
- Populate from gpuManager in handleNodeStatus
- Show GPU (used/total) column in spx top nodes; "-" when no GPUs present
* feat: Ubuntu 24.04 GPU AMI build pipeline (mulga-997)
Extends build-system-image.sh to support Ubuntu alongside Alpine.
Key differences handled: partition table (parted resizepart p1),
bind mounts for DKMS (/proc /sys /dev), apt vs apk, systemctl vs
rc-update. DISTRO defaults to "alpine" for backward compatibility.
Adds ubuntu-gpu.conf manifest and ubuntu-gpu-setup.sh chroot script
that installs nvidia-headless-550-server with DKMS pre-built against
a pinned linux-image-generic kernel, blacklists nouveau, and prevents
unattended-upgrades from invalidating the pre-built module.
* Fixed GPU passthrough and added test script
* feat: always-probe GPU at startup, surface capability in NodeStatusResponse
- Add gpuProbeResult struct and probeGPU() which runs at daemon startup
regardless of gpu_passthrough config. Checks sysfs for GPUs, IOMMU
groups, and vfio_pci module presence.
- Store gpuProbe on Daemon struct; split NewDaemon into probe (always)
and activate (opt-in) phases.

passthrough not active, 'used/total' = passthrough active.
* feat: SIGHUP hot-reload for GPU passthrough config (mulga-1001)
- Export GenerateGPUTypes for use by the reload path
- Add ResourceManager.reloadGPUTypes: mutates instanceTypes map in-place
(preserves references held by instanceService) and updates NATS
subscriptions without full daemon restart
- Separate SIGHUP from SIGTERM/SIGINT: setupReload() listens for SIGHUP
in a context-aware loop; setupShutdown no longer intercepts SIGHUP
- Add reloadConfig() + applyGPUConfig(): re-reads spinifex.toml on signal,
handles false→true (re-probe + activate) and true→false (refuse if
instances running, otherwise deactivate) transitions
* feat: spx admin gpu status/enable/disable commands (mulga-1000)
- admin.SetGPUPassthrough: Go implementation of the idempotent TOML write
(replaces the inline Python heredoc in spx-test-gpu.sh)
- spx admin gpu status: shows GPU hardware, IOMMU/vfio state, passthrough
activation, and advertised g5 instance types via NATS NodeStatusResponse
- spx admin gpu enable: checks prerequisites, writes TOML, sends SIGHUP,
polls until daemon confirms GPUPassthrough=true
- spx admin gpu disable: refuses while GPU instances are running, otherwise
writes TOML, sends SIGHUP, polls until confirmed
- spx-test-gpu.sh: replace Python TOML heredoc with spx admin gpu enable
* fixed admin
* fix: filter Intel iGPU from passthrough pool, use lspci for consumer GPU names
Discover() now skips non-NVIDIA/AMD vendors so Intel iGPUs never enter
the passthrough pool. enrichFromLspci() uses the system PCI ID database
via lspci -vmm to populate the model name for any card not in the
hardcoded table, without needing nvidia-smi or driver tools.
* fix: grant CAP_SYS_ADMIN and vfio device access to spinifex-daemon
GPU passthrough requires writing to /sys/bus/pci/drivers/vfio-pci/unbind
on instance stop. The kernel gates this on CAP_SYS_ADMIN regardless of
file permissions. QEMU subprocesses also need char-vfio rw access to
open /dev/vfio/N for the passed-through device.

* feat: re-wire GPU claim and device injection after vm.Manager refactor
GPU passthrough claim (VFIO bind) and QEMU device injection were lost
when dev's vm.Manager refactor (#185/#186) moved StartInstance/
CreateQMPClient into vm/lifecycle.go. Re-add both in their correct
new homes:
- daemon_handlers_instance.go: claim GPU before vmMgr.Run() in both
RunInstances and StartStoppedInstance handlers; release on failure
- vm/lifecycle.go startQEMU(): inject vfio-pci device with x-vga flag
derived from instance.GPUXVGAEnabled when GPUPCIAddress is set
* fix: Create spinifex user ~/.ssh and keys in firstboot
