Hi all,
I have some issues with i810 gfxdriver on DirectFB-1.1.1.
The mail is long .. please bare with me .. i have sequenced out as much info
as possible to aid in debugging !
I had the following issues:
1. I did not know the primary fb for the i810 is some how /dev/fb1 .. that
took some time for me to figure out.
[EMAIL PROTECTED] directfb]# *dmesg | grep -i i810*
agpgart: Detected an Intel i810 Chipset.
i810-i2c: Probe DDC1 Bus
i810fb_init_pci: DDC probe successful
fbcon: I810 (fb1) is primary device
I810FB: fb1 : Intel(R) 810-DC100 Framebuffer Device v0.9.0
I810FB: Video RAM : 4096K
I810FB: Monitor : H: 30-71 KHz V: 50-160 Hz
I810FB: Mode : [EMAIL PROTECTED]
so i added in directfbrc - fbdev=/dev/fb1
2. After that i do* fbset -fb /dev/fb1 *
mode "1024x768-84"
# D: 94.500 MHz, H: 68.677 kHz, V: 84.997 Hz
geometry 1024 768 1024 768 8
timings 10582 208 48 36 1 96 3
hsync high
vsync high
rgba 8/0,8/0,8/0,8/0
endmode
See the offsets are all ZEROs !!
3. So i manually set up the fb using
*fbset -fb /dev/fb1 -xres 800 -yres 600 -depth 16 -rgba 5,6,5,0
*after that
* fbset -fb /dev/fb1 *
mode "800x600-85"
# D: 56.303 MHz, H: 53.724 kHz, V: 85.142 Hz
geometry 800 600 800 600 16
timings 17761 152 32 27 1 64 3
hsync high
vsync high
rgba 5/11,6/5,5/0,0/0
endmode
i *pasted* this to the beginning of * /etc/fb.modes*
4. i run dfbinfo .. *kernel panic in EIP : i810fb_check_var*
Reason ... fbdev.c : 1835 .. call to FBIOPUT_VSCREENINFO with huge values of
Virtual RES
(gdb) p var
$9 = {xres = 1024, yres = 768, xres_virtual = 3214385416, yres_virtual =
13357344, xoffset = 0,
yoffset = 0, bits_per_pixel = 16, grayscale = 0, red = {offset = 11,
length = 5,
msb_right = 0}, green = {offset = 5, length = 6, msb_right = 0}, blue =
{offset = 0,
length = 5, msb_right = 0}, transp = {offset = 0, length = 0, msb_right
= 0}, nonstd = 0,
activate = 2, height = 0, width = 0, accel_flags = 0, pixclock = 10582,
left_margin = 208,
right_margin = 48, upper_margin = 36, lower_margin = 1, hsync_len = 96,
vsync_len = 3,
sync = 3, vmode = 0, rotate = 0, reserved = {0, 0, 0, 0, 0}}
So i changed fbdev.c:1801, fbdev.c:1802
var.xres_virtual = mode->xres*3; //vxres; SRIRAM FIX
var.yres_virtual = mode->yres*3; //vyres; SRIRAM FIX
printf("\tSRIRAM FIX:(%d,%d,%d,%d)\n", var.xres, var.yres,
var.xres_virtual, var.yres_virtual);
No Kernel PANIC ... Issue fixed
5. Now i do dfbinfo i get this !!
