in the driver (r300) i really would like to test all texture format, so is there a way to ask mesa to send me texture in a specific order (REV or not)
No. The <format> parameter describes the incoming format of the user's texture image. It may or may not have any bearing on which hardware format is chosen by the driver. More typically, the <internalFormat> parameter is used by the driver to choose the hardware texture format.
Not all the MESA_FORMAT_* texture formats are supported by all drivers.
I see. Brian, would you know - do we *have* to use _dri_texformat_xxx formats for hardware formats ?
The reason I am asking is that R300 appears to support all (or almost all)
GL texture formats and it would not be too difficult to add this support,
but we are using R200 switch() due to lack of understanding of Mesa->driver interface.
thank you !
