I'd like to see your changes posted here as a diff before they're committed. I expect that there are both platform-specific and generic powerpc parts to the changes. Is this correct?
Actually, I believe it's all generic ppc-code. Of course if we ever need more than 512MB, we will have a problem on macppc. The issue is that the kernel KVA space starts to invade device register space above 0x8000000 (USER_SR becomes 0xc so 0xc0000000). The proper way to fix this is switch macppc to the common ppc bus_space/bus_dma code and use bus_space everywhere. -- Matt Thomas Internet: matt%3am-software.com@localhost 3am Software Foundry WWW URL: http://www.3am-software.com/bio/matt/ Cupertino, CA Disclaimer: I avow all knowledge of this message
