anarsoul: done
<anarsoul>
thanks
<anarsoul>
MoeIcenowy: btw I think this weird texture format for depth reload has something to do with precision
<anarsoul>
we have only fp16 in PP but depth is 24 bit
<anarsoul>
fp16 is not enough to represent 0..1 in 24 bit
<MoeIcenowy>
anarsoul: so it has a larger precision?
<MoeIcenowy>
when directly used
<MoeIcenowy>
(like when directly use a varying in sampler

<anarsoul>
MoeIcenowy: maybe? try sampling from it and saving it into gl_FragColor?
<MoeIcenowy>
we have only 8-bit at gl_FragColor, right?

<anarsoul>
MoeIcenowy: but one per channel?
<anarsoul>
it may use several components to store 24-bit of depth
<anarsoul>
MoeIcenowy: it uses the same shader as for color reload, right?
<MoeIcenowy>
yes
<MoeIcenowy>
but from my experiment R/G channels are not very meaningful
<MoeIcenowy>
oops
<MoeIcenowy>
CI timeout
<anarsoul>
MoeIcenowy: so it's only z channel?
<MoeIcenowy>
anarsoul: seems that Z at B and S at W
<MoeIcenowy>
s/W/A/
<anarsoul>
I see
<anarsoul>
interesting
<anarsoul>
let's try assigning it to marge once again...
<anarsoul>
there's no runners for arm_build and arm_test :(

anarsoul: will it be possible to merge bypass CI?
<MoeIcenowy>
because this commit had been tested when CI is ok

"The pipeline for this merge request failed. Please retry the job or push a new commit to fix the failure"

oh the whole mesa has no new commit
<MoeIcenowy>
anarsoul: do we support derivation now?
<MoeIcenowy>
I met `extension `GL_OES_standard_derivatives' unsupported in fragment shader` in newest plasma-mobile
<anarsoul>
MoeIcenowy: I think we do
<anarsoul>
rellla implemented it quite a while ago
<MoeIcenowy>
maybe we forgot to expose it?
<anarsoul>
yeah
<anarsoul>
see PIPE_CAP_FRAGMENT_SHADER_DERIVATIVES
<MoeIcenowy>
lemme try
<MoeIcenowy>
it works, but seems that it suffers from low resolution in PP
<anarsoul>
well, we can't do anything about it
<anarsoul>
IIRC chromium workarounds it
<MoeIcenowy>
how?
<anarsoul>
I'm not sure which one but either dfdx or dfdy has lower precision than other
<MoeIcenowy>
maybe I should try to disable derivation in the shader
<MoeIcenowy>
icons are cursedly blurred when derivatives are enabled
<anarsoul>
why does it need derivatives in first place?
<MoeIcenowy>
fwidth
<anarsoul>
what is fwidth?
<MoeIcenowy>
anarsoul: Available only in the fragment shader, these functions return the sum of the absolute derivatives in xx and yy using local differencing for the input argument p. fwidth is equivalent to abs(dFdx(p)) + abs(dFdy(p)) .
<anarsoul>
MoeIcenowy: and what do they use it for in plasma?
