hv: align the MAX_IR_ENRIES to MAX_PT_IRQ_ENTRIES #6746
Conversation
The CONFIG_MAX_IR_ENTRIES and CONFIG_MAX_PT_IRQ_ENTRIES are separate configuration items, and they can be configured through configuration tool When the number of PT irq entries are more than IR entries, then some passthrough devices' irqs may failed to be protected by interrupt remapping or automatically injected by post-interrupt mechanism. And it waste memory if the CONFIG_MAX_IR_ENTRIES is larger. This patch replace the CONFIG_MAX_IR_ENTRIES to MAX_IR_ENTRIES and enforce it equal to CONFIG_PT_IRQ_ENTRIES. This way can enforce all PT irqs works with IR or PI mechanism.

I am fine with 1st patch, but not sure on the 2nd one. |
This reverts commit bf57505.
The CONFIG_MAX_IR_ENTRIES and CONFIG_MAX_PT_IRQ_ENTRIES are separate configuration items, and they can be configured through configuration tool When the number of PT irq entries are more than IR entries, then some passthrough devices' irqs may failed to be protected by interrupt remapping or automatically injected by post-interrupt mechanism. And it waste memory if the CONFIG_MAX_IR_ENTRIES is larger. This patch replace the CONFIG_MAX_IR_ENTRIES to MAX_IR_ENTRIES and enforce it align to CONFIG_PT_IRQ_ENTRIES and round up to > 2^n as the IRTA_REG spec.This way can enforce all PT irqs works with IR or PI mechanism.

When the number of PT irq entries are more than IR entries, then some
passthrough devices' irqs may failed to be protected by interrupt
remapping or automatically injected by post-interrupt mechanism.
And it waste memory if the CONFIG_MAX_IR_ENTRIES is larger.
This patch replace the CONFIG_MAX_IR_ENTRIES to MAX_IR_ENTRIES and
enforce it equal to CONFIG_PT_IRQ_ENTRIES. This way can enforce all PT
irqs works with IR or PI mechanism.
