gm45: 256M default vram
352M vram seems to be quite unstable on targets with
4GB or more. 256M has yet to show issues on different
ram configurations. This might be a good default for libreboot.

sizes from cmos + +Setting the size of the preallocated memory for the igd is done +using a cmos parameter, gfx_uma_size. This was limited to a subset of +all available sizes, that were already implemented elsewhere +in the northbridge code. + +What this does is change the cmos parameter to 4 bits instead +of 3 bits to accomodate all vram sizes. +The northbridge code that reads this cmos parameter is +also changed for this new cmos settings. + +352M is disabled since it often causes issues with 4GB or +more RAM. + +TEST: Build, flash target. Clear cmos by corrupting +the checksum (nvramtool -c something). +Set a desired value in gfx_uma_size using nvramtool. +"dmesg | grep stolen" to see what is actually allocated. + +Change-Id: Ia6479d03f1abe6d0c94bd7264365505e8f8eaeec +Signed-off-by: Arthur Heymans <arthur@aheymans.xyz> + +diff --git a/src/mainboard/lenovo/t400/cmos.default b/src/mainboard/lenovo/t400/cmos.default +index 98ce970..90d796f 100644 +--- a/src/mainboard/lenovo/t400/cmos.default ++++ b/src/mainboard/lenovo/t400/cmos.default +@@ -13,4 +13,5 @@ sticky_fn=Disable + power_management_beeps=Enable + low_battery_beep=Enable + sata_mode=AHCI +-hybrid_graphics_mode=Integrated Only +\ No newline at end of file ++hybrid_graphics_mode=Integrated Only ++gfx_uma_size=256M +\ No newline at end of file +diff --git a/src/mainboard/lenovo/t400/cmos.layout b/src/mainboard/lenovo/t400/cmos.layout +index 8e642f8..e997ed5 100644 +--- a/src/mainboard/lenovo/t400/cmos.layout ++++ b/src/mainboard/lenovo/t400/cmos.layout +@@ -76,12 +76,11 @@ entries + 939 1 e 1 low_battery_beep + 940 1 e 1 uwb + +-# coreboot config options: northbridge +-941 3 e 11 gfx_uma_size +- + # coreboot config options: graphics + 944 2 e 12 hybrid_graphics_mode +-#946 6 r 0 unused ++ ++# coreboot config options: northbridge ++946 4 e 11 gfx_uma_size + + # coreboot config options: EC + 952 8 h 0 volume +@@ -130,12 +129,18 @@ enumerations + 9 1 Primary + 10 0 AHCI + 10 1 Compatible +-11 0 32M +-11 1 48M +-11 2 64M +-11 3 128M +-11 5 96M +-11 6 160M ++11 0 1M ++11 1 4M ++11 2 8M ++11 3 16M ++11 4 32M ++11 5 48M ++11 6 64M ++11 7 128M ++11 8 256M ++11 9 96M ++11 10 160M ++11 11 224M + 12 0 Integrated Only + 12 1 Discrete Only + 12 2 Switchable +diff --git a/src/mainboard/lenovo/x200/cmos.default b/src/mainboard/lenovo/x200/cmos.default +index ac9f96d..ec7ab46 100644 +--- a/src/mainboard/lenovo/x200/cmos.default ++++ b/src/mainboard/lenovo/x200/cmos.default +@@ -13,3 +13,4 @@ sticky_fn=Disable + power_management_beeps=Enable + low_battery_beep=Enable + sata_mode=AHCI ++gfx_uma_size=256M +\ No newline at end of file +diff --git a/src/mainboard/lenovo/x200/cmos.layout b/src/mainboard/lenovo/x200/cmos.layout +index 931cb4a..a964600 100644 +--- a/src/mainboard/lenovo/x200/cmos.layout ++++ b/src/mainboard/lenovo/x200/cmos.layout +@@ -77,10 +77,10 @@ entries + 940 1 e 1 uwb + + # coreboot config options: northbridge +-941 3 e 11 gfx_uma_size +- + 944 8 h 0 volume + ++952 4 e 11 gfx_uma_size ++ + # coreboot config options: check sums + 984 16 h 0 check_sum + #1000 24 r 0 unused +@@ -125,12 +125,18 @@ enumerations + 9 1 Primary + 10 0 AHCI + 10 1 Compatible +-11 0 32M +-11 1 48M +-11 2 64M +-11 3 128M +-11 5 96M +-11 6 160M ++11 0 1M ++11 1 4M ++11 2 8M ++11 3 16M ++11 4 32M ++11 5 48M ++11 6 64M ++11 7 128M ++11 8 256M ++11 9 96M ++11 10 160M ++11 11 224M + + # ----------------------------------------------------------------- + checksums +diff --git a/src/mainboard/roda/rk9/cmos.layout b/src/mainboard/roda/rk9/cmos.layout +index f567b97..74fef63 100644 +--- a/src/mainboard/roda/rk9/cmos.layout ++++ b/src/mainboard/roda/rk9/cmos.layout +@@ -70,9 +70,9 @@ entries + 984 16 h 0 check_sum + + # coreboot config options: northbridge +-1000 3 e 10 gfx_uma_size ++1000 4 e 10 gfx_uma_size + +-#1003 21 r 0 unused ++#1004 20 r 0 unused + + # ram initialization internal data + 1024 128 r 0 read_training_results +@@ -112,13 +112,19 @@ enumerations + 8 1 Yes + 9 0 AHCI + 9 1 Compatible +-10 0 32M +-10 1 48M +-10 2 64M +-10 3 128M +-10 5 96M +-10 6 160M +- ++11 0 1M ++11 1 4M ++11 2 8M ++11 3 16M ++11 4 32M ++11 5 48M ++11 6 64M ++11 7 128M ++11 8 256M ++11 9 96M ++11 10 160M ++11 11 224M ++11 12 352M + # ----------------------------------------------------------------- + checksums + +diff --git a/src/northbridge/intel/gm45/igd.c b/src/northbridge/intel/gm45/igd.c +index 7e7bbbe..c56ecbe 100644 +--- a/src/northbridge/intel/gm45/igd.c ++++ b/src/northbridge/intel/gm45/igd.c +@@ -153,10 +153,13 @@ void igd_compute_ggc(sysinfo_t *const sysinfo) + /* Graphics Stolen Memory: 2MB GTT (0x0300) when VT-d disabled, + 2MB GTT + 2MB shadow GTT (0x0b00) else. */ + if (get_option(&gfxsize, "gfx_uma_size") != CB_SUCCESS) { +- /* 0 for 32MB */ +- gfxsize = 0; ++ /* 4 for 32MB, default if not set in cmos, ++ 8 for libreboot default of 256M*/ ++ gfxsize = 8; + } +- sysinfo->ggc = 0x0300 | ((gfxsize + 5) << 4); ++ if (gfxsize > 11) ++ gfxsize = 8; ++ sysinfo->ggc = 0x0300 | ((gfxsize + 1) << 4); + if (!(capid & (1 << (48 - 32)))) + sysinfo->ggc |= 0x0800; + } +-- +2.8.2 + |
