<Gooberpatrol66>luckyluke: nice!
<youpi>luckyluke: you can use addr2line on ext2fs.static to bulk-translate addresses
<youpi>luckyluke: "linking at the upper 2G would require adding L4 support to pmap" ... why ?
<luckyluke>As far as I understand it, to build the initial mapping, it seems currently the page tables only handle the first 8G
<youpi>with the 4-entries L3 we have 4G addressing
<youpi>I don't remember what I had set up for 64bit
<youpi>but that would largely cover 4G, wouldn't it?
<youpi>(I don't remember the details)
<luckyluke>If we link the kernel below 8G in theory yes, but in practice that fails to link above 1G. I was thinking about linking the kernel at 0xffffffff80000000, and that would need some adjustments in pmap bootstrap(), to add another entry lo L4 table and then to L3 and so on. I think that the current pmap module can't handle addresses above 8G on general.
