The PCIe endpoint user guide mentions that the ioctl TI81XX_SEND_MSI, that sends MSI targeted to specified address is presently not supported. However the PCI Ep app example/driver does show this ioctl as implemented in this function:
static int ti81xx_send_msi(void __user *argp) in the kernel subfolder drivers/char/ti81xx_pcie_epdrv.c
Has any body checked to see if this works?
If not, how does one interrupt the root complex?
The MSI support had some issues in EP driver hence it was not supported earlier and polling was used for throughput tests.
Recent driver patches (from Arago git) should support this.
