WebI was hypothesizing that a display-only kernel driver (with no driver at all in Mesa) doing dmabuf imports from GBM might be leaking GEM handles in Mesa. The program shows that it is not leaking, but there is another issue: the ioctl to close the handle does not seem right. The program uses two DRM devices: one device to allocate a GBM BO with ... WebA GEM style driver for Xilinx PCIe based accelerators. File xocl_ioctl.h defines ioctl command codes and associated structures for interacting with xocl PCI driver for Xilinx FPGA platforms. Device memory allocation is modeled as buffer objects (bo). For each bo driver tracks the host pointer backed by scatter gather list – which provides ... highways agency strike dates

Web16 okt. 2012 · The drm_ioctl function forwards all ioctl operations in range COMMAND_BASE..COMMAND_END (0x40-0xA0) using the device-specific table, and handles all others itself using its ioctls table. This ensures that all the “standard” DRM ioctls are implemented in the drm core, but card-specific drivers can implement additional ioctl … Webdeconstructor for drm_gem_objects.
