"not designed for upstream linux"
<
anarsoul>
what does it mean?
<
alyssa>
proper mainline upstream GNU/Linux
<
alyssa>
as opposed to downstream/vendor forks and Android
<
nhp>
AKA good Linux vs boring Linux :)
<
nhp>
being stuck on 4.4 is boring
<
alyssa>
nhp: okay what about being stuck on 3.14 :p
<
nhp>
At least it's pi :)

Half-tau but yes.

It occured to me overnight how to deal with vecN stuff properly
<
alyssa>
Namely, ingesting nir_op_vecN but immediately lowering to moves with writemasks in the backend.
<
alyssa>
and then those moves can get copypropped away before sched.
<
alyssa>
(possibly could also be coalesced but that's harder to get right due to sched happening first)
<
HdkR>
Sounds reasonable
<
HdkR>
Pretty sure LLVM's vector width narrowing pass does extract + combines in the IR that then get optimized away later :P
<
alyssa>
I don't want to do explicit combines in the IR
<
alyssa>
but getting combines from NIR is probably sane
<

alyssa: can you check please if x11 hits sw fallback for you in glamor with x11perf -shmgetxy500 on panfrost?
<
anarsoul>
perf top -p `pidof Xorg`
<
anarsoul>
while x11perf is running
<
alyssa>
anarsoul: dominated by fbBltPlane
<
anarsoul>
looks like you're also hitting glamor_copy_bail()
<
anarsoul>
not really OK
<
anarsoul>
*sigh* so it's something generic I guess
<
anarsoul>
I'll try to debug it, it should be faster if blits are done on GPU
<
anarsoul>
also blits on GPU wouldn't flush pending jobs for FBO

Oh, groan, but my copyprop is failing here
