From c1b1f7874c3078daedac657361dc271c189b63ca Mon Sep 17 00:00:00 2001 From: Mike Smith Date: Sat, 23 Feb 2002 05:27:49 +0000 Subject: [PATCH] Match namespace cleanup changes in ACPI CA 20020217 update. Use ACPI_SUCCESS/ACPI_FAILURE consistently. The AcpiGetInto* interfaces are obsoleted by ACPI_ALLOCATE_BUFFER. Use _ADR as well as _BBN to get our bus number. --- sys/dev/acpica/acpi_pcib.c | 56 ++++++++++++++++++++++----------- sys/dev/acpica/acpi_pcib_acpi.c | 56 ++++++++++++++++++++++----------- 2 files changed, 74 insertions(+), 38 deletions(-) diff --git a/sys/dev/acpica/acpi_pcib.c b/sys/dev/acpica/acpi_pcib.c index 57ce2a629bce..4b12a4186d88 100644 --- a/sys/dev/acpica/acpi_pcib.c +++ b/sys/dev/acpica/acpi_pcib.c @@ -44,7 +44,7 @@ * Hooks for the ACPI CA debugging infrastructure */ #define _COMPONENT ACPI_BUS -MODULE_NAME("PCI") +ACPI_MODULE_NAME("PCI") struct acpi_pcib_softc { device_t ap_dev; @@ -128,7 +128,7 @@ acpi_pcib_attach(device_t dev) ACPI_STATUS status; int result; - FUNCTION_TRACE(__func__); + ACPI_FUNCTION_TRACE(__func__); sc = device_get_softc(dev); sc->ap_dev = dev; @@ -147,7 +147,7 @@ acpi_pcib_attach(device_t dev) * Get our segment number by evaluating _SEG * It's OK for this to not exist. */ - if ((status = acpi_EvaluateInteger(sc->ap_handle, "_SEG", &sc->ap_segment)) != AE_OK) { + if (ACPI_FAILURE(status = acpi_EvaluateInteger(sc->ap_handle, "_SEG", &sc->ap_segment))) { if (status != AE_NOT_FOUND) { device_printf(dev, "could not evaluate _SEG - %s\n", AcpiFormatException(status)); return_VALUE(ENXIO); @@ -157,8 +157,8 @@ acpi_pcib_attach(device_t dev) } /* - * Get our base bus number by evaluating _BBN - * If this doesn't exist, we assume we're bus number 0. + * Get our base bus number by evaluating _BBN.
