Coreboot currently disables GS45 altogether, -but forcing coreboot to treat high-performance GS45 as GM45 makes -the X200S and X200 Tablet boot if it has the right CPU type. - -Hardcode-enable GS45 high-performance mode in coreboot, passing it -off as GM45. This is known to work with all CPUs except the SU -(low performance) models. - -The low-performance models are unsupported anyway, requiring -extensive work on the raminit. For now, this patch increases -compatibility to a whole new chipset (GS45), depending on the CPU. - -Change-Id: I2719385e93c37d254ce38e0f5f486262160234e1 -Signed-off-by: Steve Shenton <sgsit@libreboot.org> -Signed-off-by: Francis Rowe <info@gluglug.org.uk> ---- - src/northbridge/intel/gm45/raminit.c | 5 ++--- - 1 file changed, 2 insertions(+), 3 deletions(-) - -diff --git a/src/northbridge/intel/gm45/raminit.c b/src/northbridge/intel/gm45/raminit.c -index 9c4fecd..1614b7c 100644 ---- a/src/northbridge/intel/gm45/raminit.c -+++ b/src/northbridge/intel/gm45/raminit.c -@@ -108,8 +108,7 @@ void get_gmch_info(sysinfo_t *sysinfo) - printk(BIOS_SPEW, "GMCH: GS40\n"); - break; - case GMCH_GS45: -- printk(BIOS_SPEW, "GMCH: GS45, using low power mode by default\n"); -- sysinfo->gs45_low_power_mode = 1; -+ printk(BIOS_SPEW, "GMCH: GS45, using high performance mode by default\n"); - break; - case GMCH_PM45: - printk(BIOS_SPEW, "GMCH: PM45\n"); -@@ -1692,7 +1691,7 @@ void raminit(sysinfo_t *const sysinfo, const int s3resume) - { - const dimminfo_t *const dimms = sysinfo->dimms; - const timings_t *const timings = &sysinfo->selected_timings; -- const int sff = sysinfo->gfx_type == GMCH_GS45; -+ const int sff = (sysinfo->gfx_type == GMCH_GS45) && (sysinfo->gs45_low_power_mode == 1); - - int ch; - u8 reg8; --- -1.9.1 - |
