Dear All I noticed a really weird problem using DirectFB based application and ndiswrapper ( a wrapper for Windows NDIS drivers under Linux ) . Both are not connected in any way except that they are used simultaneously on the same system. If the WiFi card is inserted when the dfb-based application is not running - everything works fine, otherwise a error appears in syslog and the driver for WiFi card is not loaded. The application uses the overlay layer for its output.
Here is the error ( note the lines with asterisks *** ): kernel: ndiswrapper: driver netcg54l (BUFFALO INC.,04/18/2004,6.0.3.26) loaded kernel: PCI: Setting latency timer of device 03:00.0 to 64 *** kernel: __alloc_pages: 7-order allocation failed (gfp=0x21/0) ***kernel: ndiswrapper (NdisMAllocateSharedMemory:896): failed to allocate DMA coherent memory; Windows driver requested 409600 bytes of un-cached memory ***kernel: ndiswrapper (miniport_init:227): couldn't initialize device: C0000001 My system : VGA compatible controller: Intel Corp. 82815 CGC [Chipset Graphics Controller] (rev 04) 00:1e.0 PCI bridge: Intel Corp. 82801 PCI Bridge (rev 05) 00:1f.0 ISA bridge: Intel Corp. 82801BA ISA Bridge (LPC) (rev 05) 00:1f.1 IDE interface: Intel Corp. 82801BA IDE U100 (rev 05) 00:1f.2 USB Controller: Intel Corp. 82801BA/BAM USB (Hub #1) (rev 05) 00:1f.3 SMBus: Intel Corp. 82801BA/BAM SMBus (rev 05) 00:1f.4 USB Controller: Intel Corp. 82801BA/BAM USB (Hub #2) (rev 05) 01:08.0 Ethernet controller: Intel Corp. 82801BA/BAM/CA/CAM Ethernet Controller (rev 03) 01:0c.0 PCI bridge: Hint Corp HiNT HB4 PCI-PCI Bridge (PCI6150) (rev 04) 01:0d.0 CardBus bridge: ENE Technology Inc CB1410 Cardbus Controller Kernel: 2.4.28 Directfb: 0.9.21 ( i810 gfx driver ) ( Please do not advise to upgrade if you are not sure the upgrade can fix this particular problem ) # cat /proc/sys/kernel/shm* 134217728 134217728 4096 Thanks in advance -- Alexey Chalimov Chief Software Architect & Team Leader SerVision Ltd. http://www.servision.net 11 Hartom St. Harhotzvim, P.O.B 45205 Jerusalem, 91450 Israel Tel: +972-2-5350014 Fax: +972-2-5868683 _______________________________________________ directfb-users mailing list [email protected] http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-users
