    Code:
    Section "Device"
        Identifier "HD4350"
        Driver "radeon"
        Option "ClockGating"
        Option "DynamicPM"
        Option "ForceLowPowerMode"
    EndSection
    ...just don't let X crash or your card's going to fry again. Happened to me once already...

    The average Windows user doesn't.
    Define an average Windows user? I have been using Linux for the past 9 years and I still don't care about the ideology. For me, it is all about the best tool for the job, where the job in my definition is a secure OS where I can do the most basic tasks like web browsing, word processing, spreadsheeting and yes, watching videos and listening to music easily. The reason I use Linux is because I personally feel that it has lower cost of ownership than windows and is a lot more customisable.

    On the other hand my parents also use Linux but they simply use it because I installed it (as it was easier for me to maintain remotely) and they don't even know what Linux or Windows is. For them everything is the "computer" and they take everything else for granted.

    And with distributions like Ubuntu, you bet that the number of users who care more about usability rather than ideology are only going to increase. So don't make assumptions about the average Linux user nowadays.

    Does this work with the driver from Ubuntu 9.10 ?
    Thanks.

    This is hardly average.

    And just because you don't care about the ideology doesn't mean that others don't. Shoving closed drivers down everyone's throats so your CPU runs a bit cooler is not what everyone wants.

    I didn't, you did.

    Please provide some sources/data which would suggest your claim is true. To me, and apparently others, "average Linux user cares more about opensource than his hardware working" just doesn't pass the laugh test. It might have been true in the days of yore when no one bothered to offer pre-compiled packages because everyone using linux was either a coder or had no issue compiling programs on their own. Those days are, thankfully, long gone.

    I know the plural of anecdote isn't 'data', but count me in the "cares about using hardware features first, about opensource second" crowd. The number of nvidia users (see Phoronix Graphics survey) is also telling. Or are you saying all those nvidia users are windows users who just switched to Linux and haven't changed their hardware?

    Shoving? You got the docs, you got the free drivers (crippled as they are) what do you care what happens in the closed source driver? Are you using it at a gunpoint?

    Not with KMS in my experience. Check your /var/log/Xorg.0.log. Mine shows:
    (WW) RADEON(0): Option "DynamicPM" is not used
    (WW) RADEON(0): Option "ForceLowPowerMode" is not used

    I'm running 2.6.32-rc5 and drm/mesa/xf86-video-ati git master.

    I was clearly referring to this:

    To be fair, an average end user doesn't care about the ideology behind open source vs. closed source as long as we can get a working driver that delivers the advertised features. So can we please get something that works and have a open source vs. closed source DRM debate on the side?
    So I didn't start the debate on what the average linux user wants, I just said that I don't want the excellent work that AMD is putting into open-source drivers shouldn't be sabotaged so we can get add DRM to the binary blob faster.

    I care about open infrastructure, and there are many others who do, too. I don't want somebody else deciding that linux should be half-open and half-closed in the name of the mythical "average user".

    The number of nvidia users (see Phoronix Graphics survey) is also telling.
    Yes.

    It is telling that AMD hardware only got the ability to play videos properly on Linux a couple of months ago and that nVidia was the only option in the past.

    It is not telling that people don't want open-source drivers.

    AMD are not sabotaging open source driver work in favour of binary blobs. AMD are putting more work than was originally intended into the open source drivers.
    It was the community who said "just give us the documentation, we'll do the rest". AMD has done that, and has given extra support to help in the development of the drivers. If anything, AMD has lessened work on fglrx to help with open source stuff (though, I would point out that in doing so AMD does not have to support older video cards in fglrx).

    However, they haven't given the documentation to exploit UVD in open source drivers and reading Bridgman's comments in many threads, it is reasonable to assume that they probably never would (after a detailed study where the senior management is more than likely to veto the idea of releasing the specs if that would increase the likelihood of AMD's DRM to be broken, but only benefits a miniscule proportion of their user base).

    That is where my rant started really, that can we have the open source vs. closed source debate on the side and give top priority of getting something working out first, be it closed source or open source. As I said, according to me an average user probably doesn't care about where the driver is coming from, be it AMD or the community, as long as it works. And if your post is correct that AMD is prioritising open source over closed source, it does give me some reason to be concerned as for reasons I mentioned above, AMD are highly unlikely to release the specs for the UVD Asic to the community, but the increased focus on open source driver would probaly delay the availability of those features in their closed source driver as well. I certinaly hope it doesn't happen but can we continue having this open source vs closed source debate with AMD but without letting the users hang in the mean time?

    That's what is happening today. Other than having everything happen instantly what would you like to see changed ? I have said (about 20 times) that UVD support is likely to come out in the closed driver before the open driver, and that is still our thinking.

    In the meantime, the open source work is starting to shift focus to Gallium3D, which is a practical pre-requisite for decode acceleration *without* relying on UVD.

    I think all the things you want are happening.

    At the risk of offending everyone here, I guess I should make it clear that we are *not* waiting to see what decisions come out of the discussion on Phoronix before doing any work on open or closed drivers
