Hello,
Kernel 2.6.0-test11 has a problem with tridentfb: ----------------------------------------------------------------- Dec 10 15:16:24 (none) kernel: tridentfb: Trident framebuffer 0.7.8-NEWAPI initializing Dec 10 15:16:24 (none) kernel: tridentfb: framebuffer size = 8192 Kb Dec 10 15:16:24 (none) kernel: tridentfb: 0000:01:00.0 board found Dec 10 15:16:24 (none) kernel: tridentfb: probe of 0000:01:00.0 failed with error -22 Dec 10 15:16:24 (none) kernel: vesafb: abort, cannot reserve video memory at 0xd9800000 Dec 10 15:16:25 (none) kernel: vesafb: framebuffer at 0xd9800000, mapped to 0xc8828000, size 8128k Dec 10 15:16:25 (none) kernel: vesafb: mode is 1024x768x16, linelength=2048, pages=4 Dec 10 15:16:25 (none) kernel: vesafb: protected mode interface info at c000:65d6 Dec 10 15:16:25 (none) kernel: vesafb: scrolling: redraw Dec 10 15:16:25 (none) kernel: vesafb: directcolor: size=0:5:6:5, shift=0:11:5:0 Dec 10 15:16:25 (none) kernel: fb0: VESA VGA frame buffer device
Problem not seen in 2.4.19. Console does work in 1024x768 mode in both kernels, however I think due to vesafb in 2.6?... Here is the dmesg output for 2.4.19:
Dec 10 17:37:40 (none) kernel: tridentfb: Trident framebuffer 0.7.5 initializing Dec 10 17:37:40 (none) kernel: tridentfb: framebuffer size = 8192 Kb Dec 10 17:37:40 (none) kernel: tridentfb: Trident Microsystems CyberBlade/i7 board found Dec 10 17:37:40 (none) kernel: Console: switching to colour frame buffer device 128x48 Dec 10 17:37:40 (none) kernel: tridentfb: fb0: Trident frame buffer device 1024x768-16bpp Dec 10 17:37:40 (none) kernel: pty: 256 Unix98 ptys configured
No problems there ...
----------------------------------------------------------------- Result: Running links browser from console in graphics mode with svgalib gives :
Using Trident 9440 driver (2048K) c015e Using VESA driver, 16320KB. VBE1.2 svgalib 1.4.3
Links opens in a horizontal band of 1.5 cm height at about 1/3rd the way down from top of monitor. I am able to use the menu of links browser although I cant see the menu's complete drop down list in 1.5cm.
Links works fine with 2.4.19 ------------------------------------------------------------------ My 2.6.0-test11 kernel config file reads (--snipped--) ------------------------------------------------------------------ CONFIG_FB_VESA=y # CONFIG_FB_VGA16 is not set CONFIG_VGA_CONSOLE=y # CONFIG_LOGO_LINUX_VGA16 is not set CONFIG_VT_CONSOLE=y CONFIG_HW_CONSOLE=y # CONFIG_SERIAL_8250_CONSOLE is not set # CONFIG_LP_CONSOLE is not set CONFIG_VGA_CONSOLE=y # CONFIG_MDA_CONSOLE is not set CONFIG_DUMMY_CONSOLE=y CONFIG_FRAMEBUFFER_CONSOLE=y CONFIG_PCI_CONSOLE=y ------------------------------------------------------------------ Lilo.conf reads: --snip-- image="/boot/bzImage-2.6.0-test11" append="video=tridentfb:1024x768-16@85" label="LFS2.6" root=/dev/hdb3 read-only vga=791 /* 2.4.19 console switches to 1024x768 mode *without* this line,But not 2.6.0-test11 */ ------------------------------------------------------------------- Chipset BIOSTAR VIA MVP4 running a K62-500.

Is this a bug with trident 0.7.8-NEWAPI? Please CC reply to me, as I'm not subscribed. Thanks
