Hi,
Does multi MSI interrupts will also be set and routed by affinity ?
In drivers/pci/host/pcie-iproc-msi.c interrupt handler there is do while
loop.
head = iproc_msi_read_reg(msi, IPROC_MSI_EQ_HEAD,
eq) & IPROC_MSI_EQ_MASK;
do {
tail = iproc_msi_read_reg(msi, IPROC_MSI_EQ_TAIL,
eq) & IPROC_MSI_EQ_MASK;
.....
}
*/
} while (true);
What happens if two multi MSI cards are connected and continuously
running traffic ? Will this handler ever come out? wont this stall CPU ?
Will the interrupts be routed to different CPU's in this case also?
Regards,
Valmiki
