Does anyone have a URL? I beleive it has been available for quite some time: ftp://ftp.netbsd.org/pub/NetBSD/misc/dec-docs/index.html#dsc-chip-21030 However, there is already a volunteer working on a TGA driver as we speak. He has made substantial progress, however there are a few remaining issues to tackle (primarily the finer points of syscons integration & X server interaction). > On a totally separate issue, has anyone looked at implementing hooks > to use the performance monitoring facilities in the CPUs?
