<hellekin> so, when I meet with the guys from CEITEC, the chip fab in Brazil, what should I tell them to convince them to build free hardware?
<wpwrak> hellekin: "it's fun" ? :-)
<wpwrak> hellekin: what kind of chips do you have in mind ?
<hellekin> wpwrak: I think the best compromise would be some router stuff. They do have radio engineers, but mostly to produce RFID, so it's probably not the same as proper RF or WiFi
<hellekin> but in general, I'd like that they think about producing public infrastructure, so cheap mesh networking would be best
<wpwrak> shall we move it to #qi-hardware ?
<hellekin> as a fallback, PBX chips could be interesting. I don't see any of non-leaders building consumer nanoware anytime soon. A smartphone is very unlikely, although Brazil does have some local production (e.g., gradiente)
<hellekin> could be

<Fallenou> I think I know why adding the rcsr to the itlb miss handler made it work, and removing it made it go in endless loop
<Fallenou> somehow the value (modulo 16) of the address of instruction doing the eret is important
antgreen has joined #milkymist
<Fallenou> because if you have a icache miss while doing eret, you are going to tlb miss during itlb handler
<Fallenou> because icache miss is delaying the pipeline movement
<Fallenou> so if eret address is a multiple of 0x10 then you lose (or something like that)

<mwalle> Fallenou: athough you can do ops with vaddr now in one operations, you still need one more instruction for the or ;)
<mwalle> Fallenou: how many bits are unused in the VADDR register?
<Fallenou> hum I would say something like 11
<Fallenou> depends on your page size though :)
<Fallenou> for 4 kB pages, you have 12 unused bits, one you have to keep for TLB selection
kilae has quit [Quit: ChatZilla 0.9.88.2 [Firefox 14.0.1/20120713134347]]
<mwalle> and we encode the operation in that free bits, now?
<mwalle> except for update, which is implcitly done with writes to paddr
hypermodern has quit [Remote host closed the connection]
<Fallenou> yes that's what we agreed on :)
sh4rm4 has quit [Ping timeout: 276 seconds]
<mwalle> update is not atomic, but i guess thats ok
<Fallenou> update should run only in miss handler with no exceptions
<mwalle> Fallenou: wheres the valid bit?
<mwalle> eg if i want to read back a TLB entry

<Fallenou> mwalle: wy do you want to read back a tlb entry ?
<Fallenou> why*
<Fallenou> you have the page tables in the OS
<Fallenou> tlb can be updated or invalidated
<Fallenou> but I didn't think the OS needed to be able to read the content
<Fallenou> as of now there is no read back feature

<Fallenou> gn8!
