From 1d5b285da1893b90507b081664ac27f1a8a3dc5b Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Thu, 10 Apr 2008 19:06:43 +0400 Subject: ACPICA: Fix for resource descriptor optimization issues for _CRS/_SRC Fixed a problem where resource descriptor size optimization could cause a problem when a _CRS resource template is passed to a _SRS method. The _SRS resource template must use the same descriptors (with the same size) as returned from _CRS. This change affects the following resource descriptors: IRQ/IRQNoFlags and StartDependendentFn/StartDependentFnNoPri. http://bugzilla.kernel.org/show_bug.cgi?id=9487 Signed-off-by: Bob Moore Signed-off-by: Alexey Starikovskiy Signed-off-by: Len Brown --- drivers/acpi/resources/rscalc.c | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'drivers/acpi/resources/rscalc.c') diff --git a/drivers/acpi/resources/rscalc.c b/drivers/acpi/resources/rscalc.c index dcc51e92ac92..db0a835e3317 100644 --- a/drivers/acpi/resources/rscalc.c +++ b/drivers/acpi/resources/rscalc.c @@ -211,6 +211,13 @@ acpi_rs_get_aml_length(struct acpi_resource * resource, acpi_size * size_needed) * variable-length fields */ switch (resource->type) { + case ACPI_RESOURCE_TYPE_IRQ: + + if (resource->data.irq.descriptor_length == 2) { + total_size--; + } + break; + case ACPI_RESOURCE_TYPE_VENDOR: /* * Vendor Defined Resource: -- cgit v1.2.2
