From 78e1ca49c7ead5cd00882ed0c776260857613122 Mon Sep 17 00:00:00 2001 From: Zhao Yakui Date: Thu, 20 Sep 2007 21:23:13 -0400 Subject: [PATCH] ACPI: hpet: ACPI Error (utglobal-0126): Unknown exception code: 0xFFFFFFF0 If hpet has been initialized before registering hpet driver, the callback function of hpet_resources will return the status code of -EBUSY, which is not defined in the ACPI exception table. So when ACPI checks the status code of callback function, it will report the unknown exception code. So the status code in ACPI is used instead of the generic error code in the ACPI callback function of hpet_resources. For example: -EBUSY is replaced by AE_ALREADY_EXISTS -EINVAL is replaced by AE_NO_MEMORY http://bugzilla.kernel.org/show_bug.cgi?id=8630 Signed-off-by: Zhao Yakui Signed-off-by: Len Brown --- drivers/char/hpet.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/drivers/char/hpet.c b/drivers/char/hpet.c index 7ecffc9c738..fd51554ab08 100644 --- a/drivers/char/hpet.c +++ b/drivers/char/hpet.c @@ -943,14 +943,14 @@ static acpi_status hpet_resources(struct acpi_resource *res, void *data) printk(KERN_DEBUG "%s: 0x%lx is busy\n", __FUNCTION__, hdp->hd_phys_address); iounmap(hdp->hd_address); - return -EBUSY; + return AE_ALREADY_EXISTS; } } else if (res->type == ACPI_RESOURCE_TYPE_FIXED_MEMORY32) { struct acpi_resource_fixed_memory32 *fixmem32; fixmem32 = &res->data.fixed_memory32; if (!fixmem32) - return -EINVAL; + return AE_NO_MEMORY; hdp->hd_phys_address = fixmem32->address; hdp->hd_address = ioremap(fixmem32->address, @@ -960,7 +960,7 @@ static acpi_status hpet_resources(struct acpi_resource *res, void *data) printk(KERN_DEBUG "%s: 0x%lx is busy\n", __FUNCTION__, hdp->hd_phys_address); iounmap(hdp->hd_address); - return -EBUSY; + return AE_ALREADY_EXISTS; } } else if (res->type == ACPI_RESOURCE_TYPE_EXTENDED_IRQ) { struct acpi_resource_extended_irq *irqp; -- 2.41.1
