Changes in machdep.c http://nxr.netbsd.org/rss/src/sys/arch/evbppc/sam460ex/machdep.c en Copyright 2005 Java Fix PCI Express issues on Sam460ex.<br/>- Mapping memory region for DMA through bus_dma framework with coherency<br/> requested now causes the region to be uncached for 440 cores.<br/>- DMA inbound window mapping<br/>- Avoid configuration cycles that stall the bus<br/>- Board-specific interrupt mapping<br/><br/>Now mpt in PCI Express x4 slot does around 100MB/s to a spinning rust<br/>hard drive and is stable. /src/sys/arch/evbppc/sam460ex/machdep.c - 1.6 Mon Jun 22 00:34:19 UTC 2026 rkujawa L2 cache support on 460EX plus cache coherency fixes and USB workarounds. /src/sys/arch/evbppc/sam460ex/machdep.c - 1.5 Fri Jun 19 18:55:23 UTC 2026 rkujawa Fix up EHCI handoff from firmware on Sam460ex.<br/><br/>Sam460ex uses an external ULPI PHY. EHCI HCRESET resets only the on-chip<br/>core, never the external PHY, so it inherited the bad state. Workaround<br/>that. /src/sys/arch/evbppc/sam460ex/machdep.c - 1.4 Thu Jun 18 21:23:01 UTC 2026 rkujawa Improve console handling on Sam460ex.<br/><br/>While here: support prefetchable PCI window and fix configuration<br/>space accesses on PPC460EX. /src/sys/arch/evbppc/sam460ex/machdep.c - 1.3 Wed Jun 17 15:08:53 UTC 2026 rkujawa Make FDT parsing in Sam460ex port less bad.<br/><br/>Avoid messing directly with libfdt. /src/sys/arch/evbppc/sam460ex/machdep.c - 1.2 Tue Jun 16 23:37:49 UTC 2026 rkujawa Add support for Sam460ex by ACube Systems.<br/><br/>Still very much work in progress, but already bootable to multiuser<br/>and CPU support itself seems stable. /src/sys/arch/evbppc/sam460ex/machdep.c - 1.1 Tue Jun 16 21:51:20 UTC 2026 rkujawa
