From b40e780f8bf8f23337cf5125afdd4c3e04ec5d8c Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Tue, 17 Mar 2020 18:47:36 -0700 Subject: mb/emulation/qemu-i440fx: Add acpi_name handler for QEMU QEMU does not have a separate northbridge chip, so the mainboard needs to handle the ACPI name and paths so that devices can get generated into the SSDT properly. This fixes the PIRQ and TPM table generation. This issue can be seen in the coreboot output: ACPI_PIRQ_GEN: Missing LPCB ACPI path Change-Id: Ifc7d4359eea38ac0b55d655e39191ae7f8655fe4 Signed-off-by: Duncan Laurie Reviewed-on: https://review.coreboot.org/c/coreboot/+/39835 Tested-by: build bot (Jenkins) Reviewed-by: Patrick Rudolph Reviewed-by: Paul Menzel --- src/mainboard/emulation/qemu-i440fx/northbridge.c | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) (limited to 'src/mainboard/emulation') diff --git a/src/mainboard/emulation/qemu-i440fx/northbridge.c b/src/mainboard/emulation/qemu-i440fx/northbridge.c index 355f13cd36..74e52de095 100644 --- a/src/mainboard/emulation/qemu-i440fx/northbridge.c +++ b/src/mainboard/emulation/qemu-i440fx/northbridge.c @@ -229,6 +229,20 @@ static int qemu_get_smbios_data(struct device *dev, int *handle, unsigned long * return len; } #endif + +#if CONFIG(HAVE_ACPI_TABLES) +static const char *qemu_acpi_name(const struct device *dev) +{ + if (dev->path.type == DEVICE_PATH_DOMAIN) + return "PCI0"; + + if (dev->path.type != DEVICE_PATH_PCI || dev->bus->secondary != 0) + return NULL; + + return NULL; +} +#endif + static struct device_operations pci_domain_ops = { .read_resources = cpu_pci_domain_read_resources, .set_resources = cpu_pci_domain_set_resources, @@ -238,6 +252,9 @@ static struct device_operations pci_domain_ops = { #if CONFIG(GENERATE_SMBIOS_TABLES) .get_smbios_data = qemu_get_smbios_data, #endif +#if CONFIG(HAVE_ACPI_TABLES) + .acpi_name = qemu_acpi_name, +#endif }; static void cpu_bus_init(struct device *dev) -- cgit v1.2.3
