Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[PATCH] New PowerPC 4xx on-chip ethernet controller driver This patch replaces current PowerPC 4xx EMAC driver with new, re-written from the scratch version. This patch is quite big (~234K) because there is virtualy 0% of common code between old and new version. New driver uses NAPI, it solves stability problems under heavy packet load and low memory, corrects chip register access and fixes numerous small bugs I don't even remember now. This patch has been tested on all supported in 2.6 PPC 4xx boards. It's been used in production for almost a year now on custom 4xx hardware. PPC32 specific parts are already upstream. Patch was acked by the current EMAC driver maintainer (Matt Porter). I will be maintaining this new version.
