Hi, all. Below is a link to a brief document describing some changes in NVIDIA Falcon processors ("fuc", in Nouveau-speak, IIUC) that happened in Maxwell: certain aspects of the chip will only be available to Falcon firmware images signed by NVIDIA. So far, the set of restricted things is pretty small, but I expect this list will slowly grow over future hardware generations.

Hello, I've been debugging a few different tessellation shader issues with nouveau, but let's start small. I see this issue on my GK208 with high frequency, and I *think* I've seen it once or twice on my GF108, but it's exceedingly rare, if it does happen. I don't have a GK10x to test on, unfortunately, but I assume it'll have the same issue as the GK208. The issue is

One additional observation that I just made is that on GK208, the blob apparently doesn't use the result of S2R Rx, SR_INVOCATION_ID wholesale in TCS. It either passes it through a I2I.S32.S32 Rx, |Rx| (i.e. absolute value), or even more paradoxically, shl 2; shr 2; which removes the top *2* bits, rather than just the top 1. However I see no such behaviour on GF108. I'm going to test out

Hello, One of my GPU (GK107/NVE7) fails to properly fetch its vbios from PROM at boot time but, if I blacklist the module and load it myself later on, it always succeeds. To make things weirder, the same card works great on another computer. Here is the relevant code in Nouveau to fetch the vbios from PROM:

Hi, The VBIOS on GM20x GPUs uses a slightly updated version of the DCB. I've posted an updated DCB spec here: ftp://download.nvidia.com/open-gpu-doc/DCB/2/DCB-4.x-Specification.html You can diff it against the previous version: ftp://download.nvidia.com/open-gpu-doc/DCB/1/DCB-4.0-Specification.html to see what changed (sorry for having to diff html files). The biggest differences are

Hi all, Huge thanks again to the entire team from Intel, for their great work organizing XDC 2020, our first virtual conference! As usual we're looking for feedback on both XDC itself, and the CFP process and program selection. Both about what was great and should be kept for next year's edition, and where there's room for improvement. The board does keep some notes, for those

Hi, In the last meeting, X.Org Foundation board has decided that XDC 2020 will be a virtual conference, given the uncertain COVID-19 situation in Europe by September, including the possibility of a second wave, outbreaks and travel restrictions, either in Poland or in other countries. XDC 2020 organization team agrees on this decision and it volunteered to organize our first virtual XDC! We

Hello! Registration & Call for Proposals are now open for XDC 2020, which will take place at the Gda?sk University of Technology in Gda?sk, Poland on September 16-18, 2020. Thanks to LWN.net for hosting the website again this year! https://xdc2020.x.org As usual, the conference is free of charge and open to the general public. If you plan on attending, please make sure to register

Riley (CCed) and I will be at Plumbers in a couple weeks. There is a session on sync planned in the Android track, and of course we'll be available to chat.

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 =

Hello! Registration & Call for Proposals are now open for XDC 2023, which will take place on October 17-19, 2023. https://xdc2023.x.org As usual, the conference is free of charge and open to the general public. If you plan on attending, please make sure to register as early as possible! In order to register as attendee, you will therefore need to register via the XDC website.

Hi Nouveau developers, NVIDIA is releasing public documentation on certain aspects of our GPUs, with the intent to address areas that impact the out-of-the-box usability of NVIDIA GPUs with Nouveau. We intend to provide more documentation over time, and guidance in additional areas as we are able. As a first step towards that, we've posted a document here:

(Including a bunch more emails in the To: that got missed the first time) Hello everyone! The X.org board is soliciting proposals to host XDC in 2021. Since XDC2020 is being held virtually this year, we've decided to host in either North America or Europe. However, the board is open to other locations, especially if there's an interesting co-location with another conference. Of course
