From 8fee697d990c54976c8dc167270633299e2515d2 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Wed, 19 Aug 2009 14:55:50 +0200 Subject: x86: Add request_standard_resources to x86_init The 32bit and the 64bit code are slighty different in the reservation of standard resources. Also the upcoming Moorestown support needs its own version of that. Add it to x86_init_ops and initialize it with the 64bit default. 32bit overrides it in early boot. Now moorestown can add it's own override w/o sprinkling the code with more #ifdefs Signed-off-by: Thomas Gleixner --- arch/x86/kernel/head32.c | 1 + arch/x86/kernel/setup.c | 28 ++++++++++++++++------------ arch/x86/kernel/x86_init.c | 3 ++- 3 files changed, 19 insertions(+), 13 deletions(-) (limited to 'arch/x86/kernel') diff --git a/arch/x86/kernel/head32.c b/arch/x86/kernel/head32.c index 4049353152c..d91c37c0206 100644 --- a/arch/x86/kernel/head32.c +++ b/arch/x86/kernel/head32.c @@ -31,6 +31,7 @@ void __init i386_start_kernel(void) #endif /* Initilize 32bit specific setup functions */ x86_init.resources.probe_roms = probe_roms; + x86_init.resources.reserve_resources = i386_reserve_resources; reserve_ebda_region(); diff --git a/arch/x86/kernel/setup.c b/arch/x86/kernel/setup.c index 5796eb158d4..c2a8090e831 100644 --- a/arch/x86/kernel/setup.c +++ b/arch/x86/kernel/setup.c @@ -171,13 +171,6 @@ static struct resource bss_resource = { #ifdef CONFIG_X86_32 -static struct resource video_ram_resource = { - .name = "Video RAM area", - .start = 0xa0000, - .end = 0xbffff, - .flags = IORESOURCE_BUSY | IORESOURCE_MEM -}; - /* cpu data as detected by the assembly code in head.S */ struct cpuinfo_x86 new_cpu_data __cpuinitdata = {0, 0, 0, 0, -1, 1, 0, 0, -1}; /* common cpu data for all cpus */ @@ -605,7 +598,7 @@ static struct resource standard_io_resources[] = { .flags = IORESOURCE_BUSY | IORESOURCE_IO } }; -static void __init reserve_standard_io_resources(void) +void __init reserve_standard_io_resources(void) { int i; @@ -1013,10 +1006,7 @@ void __init setup_arch(char **cmdline_p) e820_reserve_resources(); e820_mark_nosave_regions(max_low_pfn); -#ifdef CONFIG_X86_32 - request_resource(&iomem_resource, &video_ram_resource); -#endif - reserve_standard_io_resources(); + x86_init.resources.reserve_resources(); e820_setup_gap(); @@ -1102,4 +1092,18 @@ void __init x86_quirk_time_init(void) irq0.mask = cpumask_of_cpu(0); setup_irq(0, &irq0); } + +static struct resource video_ram_resource = { + .name = "Video RAM area", + .start = 0xa0000, + .end = 0xbffff, + .flags = IORESOURCE_BUSY | IORESOURCE_MEM +}; + +void __init i386_reserve_resources(void) +{ + request_resource(&iomem_resource, &video_ram_resource); + reserve_standard_io_resources(); +} + #endif /* CONFIG_X86_32 */ diff --git a/arch/x86/kernel/x86_init.c b/arch/x86/kernel/x86_init.c index 88883f8006c..68c093b67ec 100644 --- a/arch/x86/kernel/x86_init.c +++ b/arch/x86/kernel/x86_init.c @@ -5,7 +5,7 @@ */ #include -#include +#include void __cpuinit x86_init_noop(void) { } @@ -17,5 +17,6 @@ struct __initdata x86_init_ops x86_init = { .resources = { .probe_roms = x86_init_noop, + .reserve_resources = reserve_standard_io_resources, }, }; -- cgit v1.2.3
