I have no skill to do it +09:07 < wsa> shimoday: I assume UFS needs a ufs-renesas.c file, too.

The latter is easy (did it myself, too) +09:09 < shimoday> this is because the ufs-renesas uses ufshcd-pltfrm.c +09:09 < moriperi> wsa: interesting! +09:10 < wsa> shimoday: cool, that sounds good. I was a little afraid of another SDHI-size driver on top of the UFS generic one +09:10 < wsa> geertu: real oak +09:11 < wsa> I think it would also be easy if the rooms were somewhat rectangular ;) +09:11 < shimoday> wsa: i see.

Gotcha. I was briefly wonder if it was some sort of Tensor Processor Unit +09:24 < wsa> marex: didn't you say "wants to try the aforementioned PCIe fix on Gen3 without ATF L1 link state workaround"? +09:25 < marex> wsa: that means un-patching ATF, since on Gen3, that workaround is part of ATF upstream +09:26 < wsa> I see +09:26 < geertu> marex: I assume you also want to (or already did) test the new Linux fix with the old fix in ATF? +09:27 -!- damm [~damm@m90-129-222-36.cust.tele2.se] has quit Ping timeout: 256 seconds +09:27 < marex> geertu: yes, there isn't much reason for collision, one is ARM32 only, the other is generic +09:28 -!- damm [~damm@m90-129-222-36.cust.tele2.se] has joined #periperi +09:30 -!- damm [~damm@m90-129-222-36.cust.tele2.se] has quit Remote host closed the connection +09:30 < wsa> time to core! +09:30 < wsa> geertu: enjoy! |
