| * | Phase 2: PCI Config Space & BAR Enhancements | Arthur Hanson Rasmusson | 2026-09-13 |
| | | | | | | | | | | | | | | | | | - Enhanced PCI config space write handlers in main.c: - Added MSI-X Message Control (0x72-0x73) write support - Added MSI-X Table Offset/BIR (0x74-0x77) write support - Added MSI-X PBA Offset/BIR (0x78-0x7B) write support - Enhanced BAR emulation in bar_emulation.c: - Added MSI-X Table emulation (32 entries at BAR0+0x2000) - Added MSI-X PBA emulation (64-bit at BAR0+0x3000) - Added nv_vgpu_msix_set_pending/clear_pending for interrupt injection - Integrated with GSP emulation constants from gsp_emulation.h - Updated bar_emulation.h with MSI-X struct definitions and function declarations - Added GSP emulation constants to gsp_emulation.h (MSIX offsets, polling params) | ||
| * | Phase 1: Add GSP Emulation Engine (host-side) | Arthur Hanson Rasmusson | 2026-09-13 |
| - New kernel/gsp_emulation.h: GSP emulation context and API - New kernel/gsp_emulation.c: Per-mdev emulation thread with: - Adaptive polling of doorbell at BAR0+0x110C00 - Shared memory RPC processing (4KB at BAR0+0x1000) - Dispatch for all 12 RPC types via firmware-decompiled handlers - MSI-X completion interrupt injection via eventfd - Statistics tracking (processed/failed RPCs, latency) - Modified kernel/main.c: Integrate gsp_emu_init/cleanup in device lifecycle - Modified kernel/Makefile: Add gsp_emulation.o to build - Modified kernel/gsp_rpc_client.h: Export gsp_rpc_emulation_set/is_enabled | |||
