From 5a1ff480f4ec40ace313c16b0543c7c6af09e227 Mon Sep 17 00:00:00 2001 From: Suravee Suthikulpanit Date: Tue, 22 Dec 2015 16:24:23 -0800 Subject: [PATCH] irqchip/gicv2m: Miscellaneous fixes for v2m resources and SPI ranges This patch contain fixes for v2m resources and SPI ranges: * Fix off-by-one error when set up v2m resource end range in gicv2m_acpi_init(). * Fix the off-by-one print error for SPI range. * Use %pR to properly print resource range information. Both ACPI and DT should now print: GICv2m: range[mem 0xe1180000-0xe1180fff], SPI[64:319] Suggested-by: Bjorn Helgaas Signed-off-by: Suravee Suthikulpanit Cc: Lorenzo Pieralisi Cc: Will Deacon Cc: Catalin Marinas Cc: Cc: Cc: Cc: Cc: Cc: Cc: Cc: Link: http://lkml.kernel.org/r/1450830263-28914-1-git-send-email-Suravee.Suthikulpanit@amd.com Signed-off-by: Thomas Gleixner --- drivers/irqchip/irq-gic-v2m.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/drivers/irqchip/irq-gic-v2m.c b/drivers/irqchip/irq-gic-v2m.c index e2d2d027637d..c779f83e511d 100644 --- a/drivers/irqchip/irq-gic-v2m.c +++ b/drivers/irqchip/irq-gic-v2m.c @@ -365,9 +365,8 @@ static int __init gicv2m_init_one(struct fwnode_handle *fwnode, list_add_tail(&v2m->entry, &v2m_nodes); - pr_info("range[%#lx:%#lx], SPI[%d:%d]\n", - (unsigned long)res->start, (unsigned long)res->end, - v2m->spi_start, (v2m->spi_start + v2m->nr_spis)); + pr_info("range%pR, SPI[%d:%d]\n", res, + v2m->spi_start, (v2m->spi_start + v2m->nr_spis - 1)); return 0; err_iounmap: @@ -456,7 +455,8 @@ acpi_parse_madt_msi(struct acpi_subtable_header *header, return -EINVAL; res.start = m->base_address; - res.end = m->base_address + SZ_4K; + res.end = m->base_address + SZ_4K - 1; + res.flags = IORESOURCE_MEM; if (m->flags & ACPI_MADT_OVERRIDE_SPI_VALUES) { spi_start = m->spi_base; -- 2.39.5
