Subject: [EXT] [PATCH v5 3/5] eal/interrupts: add IRQ count in interrupt
handle
External Email
----------------------------------------------------------------------
Have total number of IRQ count support in interrupt handle.
In case of VFIO this IRQ count is returned when
VFIO_DEVICE_GET_IRQ_INFO ioctl is invoked. This IRQ_count can used by
the devices to store/provide total number of interrupts available and to
enable or disable these interrupts.
Hi Nipun,
We already have "max_intr" field for the same purpose and its respective APIs
plt_intr_max_intr_set()/plt_intr_max_intr_get()
Hi Harman,
If we have a look into rte_intr_efd_enable() API, 'max_intr' being set
in this API. So once a driver is using the interrupts the 'max_intr'
would be overwritten. 'nb_intr' which is described as "Max vector count"
seems more relevant to me here and I have used 'nb_intr' to have the
total interrupt count available and sent out the updated series for CDX
bus. Please let me know in case you have separate thoughts on this.
Thanks,
Nipun
Thanks
Harman
