AJFISH	d4f167a92a	Missed a fix in the Cpu Driver. Added some more debug for Execption handling and clean up some uncached stuff. ... git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9789 6f19259b-4bc3-4df7-8a09-765794883524	2010-01-17 02:54:31 +00:00
AJFISH	f659880bfa	Added support for L2 (4K) page tables and made the CPU driver change cachability attributes on request. Also got the DebugUncache infrastructure working for the first time. Looks like it works for the simple case. Checking in so we can get more eyes looking at the code. ... git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9734 6f19259b-4bc3-4df7-8a09-765794883524	2010-01-14 03:25:08 +00:00
AJFISH	965626c940	Adding a Debug version of the UncachedMemoryAllocationLib that will make the PCI DMA address not match the CPU C address for a DMA buffer. The PCI DMA address will generate a page fault if accessed from the CPU. This should make it easy to debug EFI DMA code to make sure it is following the correct rules for which pointer to use. ... git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9725 6f19259b-4bc3-4df7-8a09-765794883524	2010-01-13 15:18:34 +00:00
