I can't seem to get an external DVD drive to show up on an CentOS 7 server. Wondering if it's just missing a driver or if I'm missing something fundamental. It's an external USB device that works fine on my Fedora 21 Laptop, but I never get a /dev/ entry (EG: /dev/sr0) on the server. What can I do to make this thing work?

I have code like this: data <- read.csv("test1.csv", stringsAsFactors=FALSE, header=TRUE) # Graph myplot=ggplot(data, aes(fill=condition, y=value, x=condition)) + geom_bar(position="dodge", stat="identity", width=0.5) + scale_fill_manual(values=c("#7b3294", "#c2a5cf", "#a6dba0", "#008837"))+

The translation also needs to be inverted, and in bypass mode the state tracker incorrectly assumes that Y = 0 = TOP, so we need inversion there to; NDC clipping has to be deactivated explicitly. --- src/gallium/drivers/nv50/nv50_state_validate.c | 31 +++++++++++++++-------- 1 files changed, 20 insertions(+), 11 deletions(-) diff --git a/src/gallium/drivers/nv50/nv50_state_validate.c

We need to invert the viewport translate/scale parameters when the state tracker thinks we have Y_0_TOP. If these cases, we have do to bypass mode by setting an identity viewport transform for x, z and inversion for y, or p.e. clear_with_quad won't work correctly. Clipping for xy in NDC space needs to be disabled then. --- src/gallium/drivers/nv50/nv50_context.h | 1 +

Hello, I've recently run into an unknown bit in Tesla shaders, and was hoping you could shed some light on it. I believe they're related to clamping of some sort. Here are 2 examples (from diff shaders): a0000401 cc054780 cvt rpi f32 $r0 f32 $r2 [unknown: 00000000 00010000] a000060d 8c014780 cvt rni s32 $r3 f32 $r3 [unknown: 00000000 00010000] [This is intel-style syntax, cvt =

I am trying to do a tutorial improvement on the wiki but I am having some problems with the auto formatting. Using httdp.conf produces http://httpd.conf when filtered. Using *.so produces .so and bold text there after. Is there any shorthand for the user for making text appear as it should without the linking and re-writes? Or does the admin have to change the filters in Instiki? Tesla

Commit eb168e26aa63f11a47d70c4555cae30691a2cd57 changed the way pipe->clear works so I figured I'd try to make an updated version, so below is the diff - my concerns/uncertainties should be contained in the comments. Or maybe you want to do it the way NV40 does it, just calling surface_fill through a utility function (althoug this does currently seem to only clear one color buffer) .

Hi Ilia, sorry for the slow response. This isn't my area of expertise, but as I understand it: * You've correctly decoded both instructions: * The first is a float32-to-float32 conversion, applying ceil() * The second is a float32-to-signed-int32 conversion, rounding to the nearest even integer * For the {float,int}-to-{float,int} operations, bit 48 indicates whether the

This moves construction of the mapping between VP outputs and FP inputs into validation. The map also contains slots for special outputs like clip distance and point size, so we need to at least merge the VP related and FP related parts on validation if we want to support those. Now we match every single FP input component with results from the VP and leave those not read out of the map, or

Hello, We're seeing a very odd issue on many (all?) tesla chips (G8x, G9x, G200, GT21x) related to looping. People will have loops in glsl like for (i = 0; i < 200; i++) { ... if (cond) break; } And it seems like if it breaks out of the loop early, all's well, but eventually it peeters out (I haven't figured out exactly when though). See bug at

Hi Andy, Thanks for checking! I do see an issue on Tesla as well (at least G92, and I believe someone else reported on a GT215 or GT218). However I haven't confirmed that it's the identical issue to what I see on Fermi with quite as much certainty as what I've checked on a GF108. (For the G92, the texture buffer object test fails in the same way it does on Fermi, but there could be

This one maps textures to sampler units (or textures to texture units or whatever it's called), which wasn't done before. It should make the mesa demo "multiarb" work, at least with the shader patches I sent earlier. Of course, with this functionality one probably wouldn't have to setup the textures in NV50_TIC anew every time, but that can be optimized later.

Turns out we used a misaligned long instruction near the end, and the shader was getting killed after writing R, A components. This has gone unnoticed since the remaining G, B outputs aren't actually used. --- src/nv50_accel.c | 5 +++-- 1 files changed, 3 insertions(+), 2 deletions(-) diff --git a/src/nv50_accel.c b/src/nv50_accel.c index 5fa539c..1218e18 100644 --- a/src/nv50_accel.c

Hello, I hope this is an appropriate style of request for this forum. I added code to support video decoding on the tesla cards that have a similar-style video decoding engine to fermi cards (i.e. G98, GT21x, the IGP's -- the falcon-controlled decoding engines, rather than the xtensa-controlled ones), by using pretty much the same logic that we had for the fermi cards. This worked great for
