From: MaJun <majun258@xxxxxxxxxx> For current ITS driver, two level table (indirect route) is enabled when the memory used for LPI route table over the limit(64KB * 2) size. But this function impact the performance of LPI interrupt actually because need more time to look up the table. Although this function can save the memory needed, we'd better let the user to decide enable or disable this function. MaJun (3): Binding: Add a new property string in ITS node to control the two-level route function irqchip/gicv3-its:irqchip/gicv3-its: add a new flag to control indirect route in DT mode irqchip/gicv3-its:irqchip/gicv3-its: Add a new flag to control indirect route function in ACPI mode. .../bindings/interrupt-controller/arm,gic-v3.txt | 3 +++ drivers/irqchip/irq-gic-v3-its.c | 19 ++++++++++++++----- include/acpi/actbl1.h | 3 ++- 3 files changed, 19 insertions(+), 6 deletions(-) -- 1.7.12.4 -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
