Hello!
I have just switched to DirectFB 0.9.24 from 0.9.22 and met some troubles with
my gfxcard initialization. I've got following message:
-----
(!) DirectFB/FBDev: Could not mmap MMIO region (offset 0, length 0)!
--> Invalid argument
(!) DirectFB/Core: Could not initialize 'gfxcard' core!
--> General I/O error!
-----
After some investigations I've found that trouble was caused by registering
'radeon' module - if I
remove /usr/lib/directfb-0.9.24/gfxdrivers/libdirectfb_radeon.*, everything
runs perfectly.
My card is ATI Technologies Inc Radeon Mobility M7 LW (Radeon Mobility 7500).
I guess, it based on r200 chipset. Here is the relevant part of `lspci -v`
output:
------
0000:01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility
M7 LW [Radeon Mobility 7500] (prog-if 00 [VGA])
Subsystem: Compaq Computer Corporation: Unknown device 00b7
Flags: bus master, stepping, 66MHz, medium devsel, latency 66, IRQ 11
Memory at 48000000 (32-bit, prefetchable) [size=128M]
I/O ports at 3000 [size=256]
Memory at 40400000 (32-bit, non-prefetchable) [size=64K]
Expansion ROM at 40420000 [disabled] [size=128K]
Capabilities: [58] AGP version 2.0
Capabilities: [50] Power Management version 2
------
Framebuffer driver is vesafb, mode is 788 (800x600x16).
My directfbrc was still unchanged from 0.9.22. Error was still present even
without own directfbrc.
Did I miss something with that release or it looks like a bug?
