From 10fccf5fda7529258325769e9da136064b481aab Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Thu, 18 Jan 2007 16:44:24 -0700 Subject: i386: turn on CONFIG_PNP in defconfig I'm trying to remove drivers/acpi/motherboard.c, which is mostly redundant with drivers/pnp/system.c. So make sure that we include the PNP driver in the default config. Most distros enable this already. Turning on CONFIG_PNP also causes the following options to be enabled: CONFIG_PNPACPI CONFIG_SERIAL_8250_PNP CONFIG_SERIAL_8250_PNP causes legacy serial ports to be discovered twice, which is ugly but harmless: serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A 00:07: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A Signed-off-by: Bjorn Helgaas Signed-off-by: Len Brown --- arch/i386/defconfig | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'arch') diff --git a/arch/i386/defconfig b/arch/i386/defconfig index 3265208e589..77927922dca 100644 --- a/arch/i386/defconfig +++ b/arch/i386/defconfig @@ -466,7 +466,8 @@ CONFIG_FW_LOADER=y # # Plug and Play support # -# CONFIG_PNP is not set +CONFIG_PNP=y +CONFIG_PNPACPI=y # # Block devices -- cgit v1.2.3 From ad71860a17ba33eb0e673e9e2cf5ba0d8e3e3fdd Mon Sep 17 00:00:00 2001 From: Alexey Starikovskiy Date: Fri, 2 Feb 2007 19:48:19 +0300 Subject: ACPICA: minimal patch to integrate new tables into Linux Signed-off-by: Len Brown --- arch/i386/kernel/acpi/boot.c | 17 +++++------------ arch/ia64/kernel/acpi.c | 8 ++++---- arch/ia64/sn/kernel/io_common.c | 17 ++++++++++++----- arch/ia64/sn/kernel/iomv.c | 10 ++++++---- arch/x86_64/kernel/time.c | 18 +++++++++--------- 5 files changed, 36 insertions(+), 34 deletions(-) (limited to 'arch') diff --git a/arch/i386/kernel/acpi/boot.c b/arch/i386/kernel/acpi/boot.c index cbcb2c27f48..9adabc4dba7 100644 --- a/arch/i386/kernel/acpi/boot.c +++ b/arch/i386/kernel/acpi/boot.c @@ -716,33 +716,26 @@ static int __init acpi_parse_fadt(unsigned long phys, unsigned long size) printk(KERN_WARNING PREFIX "Unable to map FADT\n"); return 0; } - /* initialize sci_int early for INT_SRC_OVR MADT parsing */ - acpi_fadt.sci_int = fadt->sci_int; - - /* initialize rev and apic_phys_dest_mode for x86_64 genapic */ - acpi_fadt.revision = fadt->revision; - acpi_fadt.force_apic_physical_destination_mode = - fadt->force_apic_physical_destination_mode; #ifdef CONFIG_X86_PM_TIMER /* detect the location of the ACPI PM Timer */ - if (fadt->revision >= FADT2_REVISION_ID) { + if (fadt->header.revision >= FADT2_REVISION_ID) { /* FADT rev. 2 */ - if (fadt->xpm_tmr_blk.address_space_id != + if (fadt->xpm_timer_block.space_id != ACPI_ADR_SPACE_SYSTEM_IO) return 0; - pmtmr_ioport = fadt->xpm_tmr_blk.address; + pmtmr_ioport = fadt->xpm_timer_block.address; /* * "X" fields are optional extensions to the original V1.0 * fields, so we must selectively expand V1.0 fields if the * corresponding X field is zero. */ if (!pmtmr_ioport) - pmtmr_ioport = fadt->V1_pm_tmr_blk; + pmtmr_ioport = fadt->pm_timer_block; } else { /* FADT rev. 1 */ - pmtmr_ioport = fadt->V1_pm_tmr_blk; + pmtmr_ioport = fadt->pm_timer_block; } if (pmtmr_ioport) printk(KERN_INFO PREFIX "PM-Timer IO Port: %#x\n", diff --git a/arch/ia64/kernel/acpi.c b/arch/ia64/kernel/acpi.c index ef2fe474f10..aa6f9672098 100644 --- a/arch/ia64/kernel/acpi.c +++ b/arch/ia64/kernel/acpi.c @@ -76,7 +76,7 @@ const char *acpi_get_sysname(void) { #ifdef CONFIG_IA64_GENERIC unsigned long rsdp_phys; - struct acpi20_table_rsdp *rsdp; + struct acpi_table_rsdp *rsdp; struct acpi_table_xsdt *xsdt; struct acpi_table_header *hdr; @@ -87,8 +87,8 @@ const char *acpi_get_sysname(void) return "dig"; } - rsdp = (struct acpi20_table_rsdp *)__va(rsdp_phys); - if (strncmp(rsdp->signature, RSDP_SIG, sizeof(RSDP_SIG) - 1)) { + rsdp = (struct acpi_table_rsdp *)__va(rsdp_phys); + if (strncmp(rsdp->signature, ACPI_SIG_RSDP, sizeof(ACPI_SIG_RSDP) - 1)) { printk(KERN_ERR "ACPI 2.0 RSDP signature incorrect, default to \"dig\"\n"); return "dig"; @@ -96,7 +96,7 @@ const char *acpi_get_sysname(void) xsdt = (struct acpi_table_xsdt *)__va(rsdp->xsdt_address); hdr = &xsdt->header; - if (strncmp(hdr->signature, XSDT_SIG, sizeof(XSDT_SIG) - 1)) { + if (strncmp(hdr->signature, ACPI_SIG_XSDT, sizeof(ACPI_SIG_XSDT) - 1)) { printk(KERN_ERR "ACPI 2.0 XSDT signature incorrect, default to \"dig\"\n"); return "dig"; diff --git a/arch/ia64/sn/kernel/io_common.c b/arch/ia64/sn/kernel/io_common.c index d4dd8f4b6b8..65979f1fb35 100644 --- a/arch/ia64/sn/kernel/io_common.c +++ b/arch/ia64/sn/kernel/io_common.c @@ -25,7 +25,6 @@ #include "xtalk/xwidgetdev.h" #include #include -#include extern void sn_init_cpei_timer(void); extern void register_sn_procfs(void); @@ -37,7 +36,6 @@ extern void sn_legacy_pci_window_fixup(struct pci_controller *, u64, u64); extern void sn_io_acpi_init(void); extern void sn_io_init(void); - static struct list_head sn_sysdata_list; /* sysdata list struct */ @@ -50,6 +48,15 @@ int sn_ioif_inited; /* SN I/O infrastructure initialized?

This extension was into a reserved field that firmware should set to 0, but the HP simulator had non-zero values there resulting in unexpected huge numbers. So mask the domain down to 8-bits for now. A more general fix will be to check the table version supplied by firmware and get paranoid about reserved fields.
