registers +MIME-Version: 1.0 +Content-Type: text/plain; charset=UTF-8 +Content-Transfer-Encoding: 8bit + +According to "G45: Volume 3: Display Register +Intel ® 965G Express Chipset Family and Intel ® +G35 Express Chipset Graphics Controller" some registries +are set incorrectly in gm45/gma.c. + +Some values are changed after comparing them with the values +the i915 linux kernel (3.13 was used) module sets while modesetting. +The values were obtained using 'intel_reg' from intel-gpu-tools, +during a normal boot and with 'nomodeset' as a kernel argument. + +Some registers that don't exist on gm45 are set in gma.c, which is +probably the result of copying code from a more recent intel +northbridge. + +The result is that that gm45 laptops with wxga displays still work as +before. Laptops with wxga+ displays previously did not display anything +and now have a horizontal 20% strip of working display. + +TEST: build with native graphic init and flash on a gm45 target, like +lenovo x200. + +Change-Id: If66b60c7189997c558270f9e474851fe7e2219f1 +Signed-off-by: Arthur Heymans <arthur@aheymans.xyz> +--- + src/northbridge/intel/gm45/gma.c | 110 +++++++-------------------------------- + 1 file changed, 18 insertions(+), 92 deletions(-) + +diff --git a/src/northbridge/intel/gm45/gma.c b/src/northbridge/intel/gm45/gma.c +index a89f9bb..b02c89b 100644 +--- a/src/northbridge/intel/gm45/gma.c ++++ b/src/northbridge/intel/gm45/gma.c +@@ -47,60 +47,6 @@ void gtt_write(u32 reg, u32 data) + write32(res2mmio(gtt_res, reg, 0), data); + } + +-static void power_port(u8 *mmio) +-{ +- read32(mmio + 0x00061100); // = 0x00000000 +- write32(mmio + 0x00061100, 0x00000000); +- write32(mmio + 0x00061100, 0x00010000); +- read32(mmio + 0x00061100); // = 0x00010000 +- read32(mmio + 0x00061100); // = 0x00010000 +- read32(mmio + 0x00061100); // = 0x00000000 +- write32(mmio + 0x00061100, 0x00000000); +- read32(mmio + 0x00061100); // = 0x00000000 +- read32(mmio + 0x00064200); // = 0x0000001c +- write32(mmio + 0x00064210, 0x8004003e); +- write32(mmio + 0x00064214, 0x80060002); +- write32(mmio + 0x00064218, 0x01000000); +- read32(mmio + 0x00064210); // = 0x5144003e +- write32(mmio + 0x00064210, 0x5344003e); +- read32(mmio + 0x00064210); // = 0x0144003e +- write32(mmio + 0x00064210, 0x8074003e); +- read32(mmio + 0x00064210); // = 0x5144003e +- read32(mmio + 0x00064210); // = 0x5144003e +- write32(mmio + 0x00064210, 0x5344003e); +- read32(mmio + 0x00064210); // = 0x0144003e +- write32(mmio + 0x00064210, 0x8074003e); +- read32(mmio + 0x00064210); // = 0x5144003e +- read32(mmio + 0x00064210); // = 0x5144003e +- write32(mmio + 0x00064210, 0x5344003e); +- read32(mmio + 0x00064210); // = 0x0144003e +- write32(mmio + 0x00064210, 0x8074003e); +- read32(mmio + 0x00064210); // = 0x5144003e +- read32(mmio + 0x00064210); // = 0x5144003e +- write32(mmio + 0x00064210, 0x5344003e); +- write32(mmio + 0x00064f00, 0x0100030c); +- write32(mmio + 0x00064f04, 0x00b8230c); +- write32(mmio + 0x00064f08, 0x06f8930c); +- write32(mmio + 0x00064f0c, 0x09f8e38e); +- write32(mmio + 0x00064f10, 0x00b8030c); +- write32(mmio + 0x00064f14, 0x0b78830c); +- write32(mmio + 0x00064f18, 0x0ff8d3cf); +- write32(mmio + 0x00064f1c, 0x01e8030c); +- write32(mmio + 0x00064f20, 0x0ff863cf); +- write32(mmio + 0x00064f24, 0x0ff803cf); +- write32(mmio + 0x000c4030, 0x00001000); +- read32(mmio + 0x00044000); // = 0x00000000 +- write32(mmio + 0x00044030, 0x00001000); +- read32(mmio + 0x00061150); // = 0x0000001c +- write32(mmio + 0x00061150, 0x0000089c); +- write32(mmio + 0x000fcc00, 0x01986f00); +- write32(mmio + 0x000fcc0c, 0x01986f00); +- write32(mmio + 0x000fcc18, 0x01986f00); +- write32(mmio + 0x000fcc24, 0x01986f00); +- read32(mmio + 0x00044000); // = 0x00000000 +- read32(mmio + LVDS); // = 0x40000002 +-} +- + static void intel_gma_init(const struct northbridge_intel_gm45_config *info, + u8 *mmio, u32 physbase, u16 piobase, u32 lfb) + { +@@ -150,8 +96,6 @@ static void intel_gma_init(const struct northbridge_intel_gm45_config *info, + for (i = 0; i <= 0x18; i++) + vga_cr_write(i, cr[i]); + +- power_port(mmio); +- + intel_gmbus_read_edid(mmio + GMBUS0, 3, 0x50, edid_data, 128); + decode_edid(edid_data, + sizeof(edid_data), &edid); +@@ -277,28 +221,32 @@ static void intel_gma_init(const struct northbridge_intel_gm45_config *info, + (hpolarity << 20) | (vpolarity << 21) + | (mode->lvds_dual_channel ?
