You found a bug, it isn't serious because the private part of the sarea isn't really manipulated in the ddx driver after initialization if I remember correctly. The client side driver will make sure there are sane values in there. The client side fyi uses the kernel defination (on the I810 anyhow).
Add the fields to the top of the user space declaration and you should still work correctly. -Jeff -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Jens Owen Sent: Tuesday, April 02, 2002 11:33 PM To: dri-devel Cc: Jeff Hartmann Subject: i810 sarea private offset question I have a question regarding the i810 sarea private declarations. Looking at the i810 driver's sarea, I see something strange. All the other drivers have identical definitions for both their user space declaration (<DRIVER>SAREAPrivRec) and their kernel space declaration (drm_<DRIVER>_sarea_t). However, the i810 driver has 4 large fields at the top of it's kernel declaration that are not present in the corresponding user space declaration: unsigned int ContextState[I810_CTX_SETUP_SIZE]; unsigned int BufferState[I810_DEST_SETUP_SIZE]; unsigned int TexState[2][I810_TEX_SETUP_SIZE]; unsigned int dirty; I'm guessing there has to be some adjustments made to the SAREA pointers to make the remaining fields line up, but I haven't found anything in the code. Has anyone (Jeff) seen an SAREA pointer adjustment that accounts for why this works? -- /\ Jens Owen / \/\ _ [EMAIL PROTECTED] / \ \ \ Steamboat Springs, Colorado _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
