<marta_> Adrinael, igt at tools_test@tools_test is 100% incomplete in drmtip runs
on fi-cnl-drrs, I did a new bug for this
https://bugs.freedesktop.org/show_bug.cgi?id=105663
<mlankhorst> vsyrjala: could we unify skl sprite mod supported and primary mod
supported?
* jsaa has quit (Quit: Leaving.)
<mlankhorst> the identical name probably gives a clue that they should be
unified
<vsyrjala> there is a patch for that on the list as well
<vsyrjala> though it needs a rebase after this one
-SaslServ- <Unknown user (via
SASL):host217-101-static.9-188-b.business.telecomitalia.it> failed to login to
marta.  There have been 334 failed login attempts since your last successful
login.

login to marta.  There have been 335 failed login attempts since your last
successful login.
* jeffmc (~jeff.mcge at 134.134.139.76) has joined
<mlankhorst> we should probably do that first
<Adrinael> marta_, when the machine is idle, can you sneak in and run these
commands:   intel_reg read 0x4030,   intel_reg dump
<Adrinael> That's all tools_test at tools_test is doing
<Adrinael> marta_, works on other cnls?
<marta_> Adrinael, yes only the drrs, so probably BIOS again...
<Adrinael> Executing those commands will tell whether the issue is real (or
test is f00ked), or fallout from other things
<marta_> Adrinael, I don't think I dare to do that tsa, might be mad if I hang
the machine...
<Adrinael> We can possibly convince tsa to do that himself :P
<vsyrjala> mlankhorst: i don't want to push all that to drm-misc-next, which is
where we need this thing to land
<marta_> Adrinael, yeah better ask tsa, maybe I don't know which machine it is
;)
<Adrinael> What register is 0x4030 anyway, is that kosher on cnl
<vsyrjala> why isn't elk included in bat runs?
* vsyrjala has probably asked before and forgot
<vsyrjala> oh because it is
* vsyrjala just cliked th wrong link
<mlankhorst> ah
<ickle> 0x4030 was replace by 0x4a08
<ickle> who know what now lies behind box 0x4030
<tsa> Adrinael: cnl-drrs: (0x00004030): 0x00004000
<tsa> ickle: (0x00004a08): 0x00000000
<Adrinael> So it didn't hang?
* Notify: jsaa is online (Ubuntu Servers (freenode))
* jsaa (~jsaa at 134.134.139.76) has joined
<Adrinael> What about dump?
* kumarmah (~mahesh at nat/intel/x-qhldvlnfzhfrbanj) has joined
<tsa> Adrinael: dump whatnow
<tsa> reg dump hangs, yes
<vsyrjala> hmm. whatis gdr?
* pekkari has quit (Quit: Konversation terminated!)
* krogovin (~kevin at 91-150-49-145.customer.karistelefon.fi) has joined
<Adrinael> If I read the output correctly, it reads PFC_CTL_1 successfully, and
hangs reading PFC_WIN_POS
* vbelgaum (Thunderbir at nat/intel/x-tdnndqaffrkqfnkc) has joined
<vsyrjala> those register offsets are bogus
<vsyrjala> hmm. or c, maybe not.
<vsyrjala> well, they are bogus for skl+
