| 2016-02-25 | genirq: Implement ipi_send_mask/single() | Qais Yousef | 1 | -1/+156 | |
| Add APIs to send IPIs from driver and arch code. We have different functions because we allow architecture code to cache the irq descriptor to avoid lookups. Driver code has to use the irq number and is subject to more restrictive checks.

| 2016-02-25 | genirq: Add a new function to get IPI reverse mapping | Qais Yousef | 1 | -0/+34 | |
| When dealing with coprocessors we need to find out the actual hwirqs values to pass on to the firmware so that it knows what it needs to use to receive IPIs from and send IPIs to Linux cpus. [ tglx: Fixed the single hwirq IPI case. The hardware irq number does not change due to the cpu number ] Signed-off-by: Qais Yousef <[email protected]> Cc: <[email protected]> Cc: <[email protected]> Cc: <[email protected]> Cc: <[email protected]> Cc: <[email protected]> Cc: <[email protected]> Cc: Qais Yousef <[email protected]> Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Thomas Gleixner <[email protected]> | |||||
| 2016-02-25 | genirq: Add a new generic IPI reservation code to irq core | Qais Yousef | 1 | -0/+137 | |
| Add a generic mechanism to dynamically allocate an IPI. Depending on the underlying implementation this creates either a single Linux irq or a consective range of Linux irqs. The Linux irq is used later to send IPIs to other CPUs. [ tglx: Massaged the code and removed the 'consecutive mask' restriction for the single IRQ case ] Signed-off-by: Qais Yousef <[email protected]> Cc: <[email protected]> Cc: <[email protected]> Cc: <[email protected]> Cc: <[email protected]> Cc: <[email protected]> Cc: <[email protected]> Cc: Qais Yousef <[email protected]> Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Thomas Gleixner <[email protected]> | |||||
