| | | | | | 1=linear) and a buffer-allocation type-retry loop; wall2: the QEMU-gdbstub kernel-breakpoint script (module VAs insert+patch but never fire - the stub's memory context does not resolve module VAs) and the kcore symbol dumper; session findings: the vkAllocateMemory -2 = the image's internal COMPR 2MB-page 64KB sub-allocation failing NV_ERR_NO_MEMORY after the image data alloc succeeds (both tilings) | ||
| * | tools/vk + nvkmstrace: real-Vulkan probe stack for the emulated vGPU - ↵ | Arthur Hanson Rasmusson | 42 hours |
| vk_probe/vk_probe2 (ctypes loader probes: enumerate + create device/queue), vk_frame (headless Vulkan compute renderer: loads the NVIDIA ICD, paints a plasma into an RGBA8 storage image, reads it back to PPM and publishes frames into the kvmfr ivshmem BAR), vk_plasma.comp -> SPIR-V; nvkmstrace.c (LD_PRELOAD NVKMS ioctl logger that decoded the vkCreateDevice failure to ALLOC_DEVICE cmd=0). Measured: the NVIDIA device enumerates and its Vulkan ICD loads (2 ICDs: NVIDIA + llvmpipe); vkCreateDevice fails VK_ERROR_INITIALIZATION_FAILED because nvKmsAllocDevice returns non-success after the display shim | |||
