X Census (for 1.10)

February 28, 2011

Following is the census of 1.10 window for all X infrastructure – raw numbers here. I did it in a similar way as the previous version. Worth to mention that there’s almost no relation between the cycles of development from each of the components listed below, which can lead to some misunderstanding. Anyway, still a nice indicative to see and evaluate how the free desktop community behaved.

Numbers for X implementation (xserver, proto, lib and xcb repositories):

About Nokia and Microsoft alliance? I was deeply shocked yes, but well, I guess I’m cool and over it now. I’m sure MeeGo is not dead by any chance though… Nevertheless, Nokia’s contribution to X11 development will be obviously diminishing. It’s sad. Our Graphics Team were just feeling the first effects of the new introduced culture for pushing whatever work (well the ones we are allowed) to upstream and now all was cracked down. So, unfortunately this won’t happen with the same volume anymore and the collected numbers of 1.10 is definitely a mark for Nokia.

late Christmas gift: freedesktop’s Xorg for MeeGo

December 29, 2010

Moikka.

If you follow here [0] you will see a set of Debian packages that Graphics team at Nokia are continuously working to deploy a X11 implementation for MeeGo-Harmattan, where we target embedded systems only. Feel free to use it!


At this point, we are very proud of ourselves because 99% of the content on these repositories are based on the ones at X main-stream of development. IWO we are directly fetching the X code-base from freedesktop.org. More important, we are shaping freedesktop implementation for embedded devices. So at this moment, we are pretty much aligned with X version 1.9.2, plus a few of other commits from master branch; the rest of components, like client side libraries, are mostly what we have on freedesktop master also.

We are quite happy because it follows exactly what we’ve planned some time ago when we strategically decided to contribute to X at freedesktop community, centralizing the development there and not ignoring it. So, no-no for kdrive, no-no for massively code-drop on the top of freedesktop’s, no-no for a proprietary X implementation, no-no for major hacks or anything like that. Aside from the video driver stack, everything was dumped at freedesktop.

Next, the plan pretty much fits with MeeGo-MeeGo cause we just needs to get the work we’ve been doing straight from freedesktop, avoiding any cross fetching between down-streams of development. Hyvää!

[0] yeah, the name of the repository is not trivial at all – and probably we will change it in a near future. So poke me if you need this later on.

X Census (for 1.9)

September 2, 2010

Topic’s name is a funny (and friendly) devotion to GNOME Census. So let’s take a look at some numbers from the time Xorg 1.9 was in development – raw data is here.

Would be unfair to measure only the work that happened e.g. in X server or in the drivers being developed and come up with the statistics about “who developed X”. X and X development community are quite extensive and don’t concern only “graphics” related, i.e., pixel information that appears on your display screen. This is a very common mistake.


X does input device event processing, device keys mapping (e.g. keyboard), pixel rasterization, output and input devices hotplug and configuration, devices and user session pairing, (different) 2D/3D graphics implementation, frame-buffer content management, X application and session security, application memory resources testing, analysis and debugging and etc. So it’s far from just pixel showing up on screen.

X is a generic graphical system. I prefer to see X as an implementation that doesn’t handle (or should not) system-level resources like memory or frame-buffer content. Other people see a bit differently. Given so, I divided all X development in the following groups, that you’ll see below as bold. Statistics were generated from the time people were working on 1.9 Xorg (02 Apr to 20 Aug):

The proto set of repositories represents the X11 core protocol description together with its extensions. The implementation of X11 and extensions to be used by clients are inside lib and xcb. lib also contains some few libraries to be used within xserver. xserver contains the server implementation of X. So here are the numbers for X implementation (xserver, proto, lib and xcb repositories):

Nothing or close to nothing was done in the old font scheme (font repo), bitmap and cursor data. Also, from the total of 85 X traditional applications (apps), only 180 changesets were made and mostly concerning autoconf clean up.

Of course lines of code and changeset are far from being a good metric to see actually how the development happened. But still, it does represents something. For sure, there’s also a lot of other inaccurate information that I’m missing from this all. For instance, companies like Collabora does X development but sometimes get the merits for Nokia. Is that fair? I don’t know. And I don’t want to discuss this either :)

PS: Canonical, where are you here? Hint hint hint.

Customization and true modularization of Xorg

January 23, 2010

For the first time in life, Xorg is being used in a single platform and for a given device only (other devices have used an X11 implementation but using other non-canonical servers, such kdrive’s based – Tiny-X).

Previously Xorg was being packed to run in a huge amount of OSes – mostly Linux and Unix-like distributions – with the characteristic of be architecture portable and able to run on a huge set of video and input devices. In terms of software, this means an extensive amount of code able to cover all of this mentioned. But this is far from the needs of a small and single platform device.

Some days ago, at #xorg-devel, Alan mentioned the following:


06:59 < alanc> vignatti: the whole point of Xorg is to drive video output - where else would you possibly sanely put that code?
07:00 < alanc> I think you're going overboard in the drive to remove all code from Xorg

Alan was referring about my previous comment to remove some code of video memory mapping from server… I understand (and respect a lot) his concerns but lemme put this right here: it’s not about removal of code; I don’t even care if the code is in xserver or not; what I do care is about the customization – or more fancy, the true modularization [0] – of Xorg.

As discussed on the last X conference, we’re aiming to optionalize [1] lot of components inside Xorg: distros would build all components, satisfying all supported devices and drivers, whereas constrained environments (such as maemo + n900) would use a restrict set only.

So recently I’ve been confusing people’s mind trying to in fact optionalize several components of the server. There are some straightforward modifications on the code like turn off libdrm, vgahw or libxdmcp, but there’s also other more challenger like all the old-school mechanism to initialise cards, to remove cursor support or even to choose if we want or not all bus subsystem. Sometimes we’ll have to be careful to not run out of the protocol. But the truth is: the currently the code is _very_ tied all over the server. It’s not trivial to “get there”.

IMHO the plan traced at XDC looks perfectly clear and while other display systems seems not suitable enough for us yet, I’ll be keep digging on this direction.

[0] the modularization that happened in the version 1.0 was related with drivers going outside the server.

[1] what would be a good word here?

Portland, OR

I was so proud for the forth time be part of the X crew, this time in Portland. Really amazing the city. I had the opportunity to play tourist and visit some nice places.

My X conferences

BTW, I just collect the photos of all four X conferences that I’ve attended. It’s not much photos but there’s some funny things :)

X on embedded

The cool thing of the work that I’m doing at Nokia is that I can publish and discuss mostly all X fun with the open source communities. “Mostly” because, for the last device – the N-shiny-and-awesome-900 – for instance, the video driver is closed (provided by Imagination), so we cannot comment much regarding such driver stack :( C’est la vie.

So we’ve been using Xorg for our small devices (FWIW the development of kdrive based servers is dead! Period). Therefore, myself and Oliver brought to XDC some discussions that we had about X server for tiny systems. Xorg DDX is still too fat. There’s a lot of code that we can cut off and that was the whole idea of our talk, more concerned about Xorg’s memory footprint.

Life is beautiful

6 months living in Helsinki: hosted 4 visits of friends, 5 new European countries visited and an average of 2 pints per day :) Lot of fun and no time at all for opensource pet projects. Even so, I’m enjoying! Besides, I bought an skate board and I’m speaking the first Finnish words already. I’m happy also that I’m (finally) finding time again to appreciate a good music (but didn’t get a guitar yet for me here). Let’s see what will be my next musical project… Nähdään!

Nokia, FI…
