[Openchrome-users] Unknown Card-Ids

Mon Jun 26 22:55:58 PDT 2006

Sorry, let me be clearer.  The CN700 is being recognised as 1106/3344 
(which is the same as my chipset, i.e. Unichrome Pro), however 
recognition of the type of chipset is *not* sufficient.

Elsewhere in the code there is a bandwidth calculation for the memory to 
see what resolutions can be supported... it is here that you need to fix 
it so something higher than 640x480/16bit is allowed as a setting.

Specifically this occurs in the via_mode.c code... in this routine:

	CARD32 ViaGetMemoryBandwidth(ScrnInfoPtr pScrn)

The table you need to fix is in via_mode.h, in the section headed 
"Bandwidth", because the routine above is getting a value that is not 
defined in the ViaBandwidthTable.

P.

I have patched my code to make this all work well for my MythTV HTPC, 
but have not produced patches for folks as yet. Since I did the code, 
the Unichrome code has moved and *some* of my patches are no longer 
required.  Just don't have the time to poke at it right now, sorry. In 
the meantime here's a snip from my via_mode.h for reference:

/*
  * Bandwidth
  *
  */
/* used for impossible entries: allow a minimum bandwidth in case
    this does happen */
#define VIA_BW_MIN 74000000 /* > 640x480 at 60Hz at 32bpp */

/* index to table */
#define VIA_BW_CLE266A  0
#define VIA_BW_CLE266C  1
#define VIA_BW_KM400    2
#define VIA_BW_KM400A   3
#define VIA_BW_K8M800   4
#define VIA_BW_PM800    5
#define VIA_BW_VM800    6
#define VIA_BW_P4M800   7    /* My entry for the P4M800CE chipset */
#define VIA_BW_ALL      8

/*
  * 393216000 is for SDR133 in via_refresh.h
  * 460800000 is for DDR266
  * 921600000 is for DDR533 - a rough guess for the BW_MAX for P4M800CE
  * maybe we need 2x that for DDR2/533???
