WebOct 5, 2024 · So if we want to raise an interrupt IRQ11, programmatically we have to add 11 to a vector of IRQ0. 0x20 + 0x10 + 11 = 0x3B (59 in Decimal). Hence executing “asm("int $0x3B")“, will raise interrupt IRQ 11. The instruction will be executed while reading the device file of our driver (/dev/etx_device).Driver Source Code WebUserspace can use this to detect support for discovering the dma-buf size using llseek. In order to avoid fd leaks on exec, the FD_CLOEXEC flag must be set on the file descriptor. This is not just a resource leak, but a potential security hole. ...
