I915 memory. I want to check the real memory usage by the GPU.
I915 memory. Memory at e2000000 (64-bit, non-prefetchable) [size=16M] All memory is encapsulated within GEM buffer objects (usually created with the ioctl DRM_IOCTL_I915_GEM_CREATE). Let’s check the most common problems and how to fix them. DRM Driver uAPI ¶ drm/i915 uAPI ¶ uevents generated by i915 on its device node I915_L3_PARITY_UEVENT - Generated when the driver receives a parity mismatch event from the GPU L3 cache. Let's check a few things : Subsystem: Lenovo CometLake-U GT2 [UHD Graphics] Flags: bus master, fast devsel, latency 0, IRQ 158. For a comprehensive list of Intel GPU models and corresponding chipsets and CPUs, see Wikipedia:Intel Graphics Technology and Gentoo:Intel#Feature support. Some systems may have compatibility issues between the system BIOS and the Linux kernel Memory-Mapped I/O Base Address Register (MMIO BAR) reallocation, which prevents the Intel® Data Center GPUs from being accessible after the system boots. To clarify the docs a bit, GSM is the portion of stolen memory for the GTT, DSM is the rest of stolen memory used for misc things. . An ioctl providing a batchbuffer for the GPU to create will also list all GEM buffer objects that the batchbuffer reads and/or writes.
