    and THIS is a PR disaster!
    Exactly. It really seems to me that the PR team has thought: "Whatever, they are the Linux users, they will take what we give them." And after they saw the outcry about that behavior they had to change something very fast.

    also why not tell the people something like this: there will be a latency driver update until the opensource driver radeon get some power managment fixes.
    then the people can use the catalyst and after the radeon driver gets usable on notebooks with power management they can switch to the radeon driver.
    Seems to me that you should ask for a job in their PR department. That would have been the right way to do it.

    the radeon driver is so close to be a good replacement for the catalyst on hd2000-hd4000 hardware but i can not unterstand why amd don't invest the money to get the last bits done to make it usefull also for notebooks.
    I disagree, it is not only the power management, but also things like video decoding and performance. Well, i don't care much about the performance on my laptop, it is not intended to be used for gaming, but the video decoding thing is definitely something that has to work.

    I would like to see support for the statement that there are people "who have been very angry" over this.
    Does anybody actually care?

    I sure don't.
    Blob be dead.

    Follow the link and you will see it. I am one of those people that are angry and care, since the radeon driver is unusable for me due to thermal problems that don't occur with Catalyst.

    This is slightly good news for HD 2000/3000/4000 series owners where the open-source AMD Radeon Linux driver just doesn't cut it yet due to poor performance, missing features (CrossFire, PowerPlay, etc), or bad battery life / thermal performance.

    There seems to be some good news on the performance front for the open source Radeon driver in the 3.5-rc1 kernel:

    and finally Alex and Jerome managed to track down a magic set of bits
    that on certain rv740 and evergreen cards allow the correct use of the
    complete set of render backends, this makes the cards operate
    correctly in a number of scenarios we had issues in before, it also
    manages to boost speed on benchmarks my large amounts on these
    specific gpus.

    Although this talks about the newer cards, there is this commit:

    drm/radeon: fixup tiling group size and backendmap on r6xx-r9xx (v4)

    Tiling group size is always 256bits on r6xx/r7xx/r8xx/9xx. Also fix and
    simplify render backend map. This now properly sets up the backend map
    on r6xx-9xx which should improve 3D performance.

    Vadim benchmarked also:
    Some benchmarks on juniper (5750), fullscreen 1920x1080,
    first result - kernel 3.4.0+ (fb21affa), second - with these patches:

    Lightsmark: 91 fps => 123 fps +35%
    Doom3: 74 fps => 101 fps +36%

    Signed-off-by: Alex Deucher
    Signed-off-by: Jerome Glisse

    Can Michael or someone benchmark the 3.5-rc1 kernel and an older kernel (perhaps 3.4) on one of the older cards that is going to be unsupported by Catalyst?

    Thumbs up

    Sorry no older card to test here. Just to confirm the performance boost on juniper (5750) with 3.5-rc1.

    Just ran the benchmark within FEAR @1400x1050 custom settings.

    kernel: 3.4 => 3.5-rc1
    -----------------------------------------
    min : 18 fps => 28 fps +55%
    avg : 32 fps => 49 fps +53%
    max: 69 fps => 109 fps +58%

    That's quite significant

    thats why : "Seems to me that you should ask for a job in their PR department." they can not promise stuff they can't deliver because they can't fix the "video decoding" problem because of the Copyprotection security DRM UVD blablabla also "performance" is not a criteria for latency support if you want performance you need to buy new hardware thats because ALL companys make money on "Performance".

    yo know 480p videos work well with XV in the radeon driver and if your vanity needs to run copy-protected DRM-Blue-ray shit you have to buy a new notebook its the same with a stand alone blue-ray player if your player DRM is hacked and is out of grantee time you have to buy a new one because he gets blacklisted from the blue-ray codes. in modern time you only rent a functionality for 2-3 years and after that you have to pay again for the same functionality!

    I am neither talking about 480p video (any simple dual-core, if not even single-core can decode that) nor about copy-protected BluRay stuff. Nowadays even the more simple video-cameras for home use produce HD stuff (1080i/p) and the HD3200 in my laptop should be able to play that without any problem. If the driver supports it.

    i'm sure you only use your 1080p video camera to warez kino movies and upload it to pirate bay ......

    this means supporting HD video withouer DRM is supporting pirates ........ and this can't be right

    LOL just kidding

    I have an older laptop that I'd love to throw linux on, and save my win7 license for a new machine. But it's got an mobility hd2600, and under linux its been terrible. Catalyst provides decent temps and battery life, but I've had issues with it (and now the hd2000 series isn't even properly supported anymore). The OSS driver is just a no-go. It has acceptable performance for compiz, but anything more than that it struggles. And worst of all the battery life and heat are unusable with the OSS drivers. It will overheat if you so much as look at it wrong, even with the profile forced to low. Dynpm hardly works and causes flickering, and forcing it to low profile noticeably impacts compiz performance.

    I ended up just saying "screw this", and buying a cheap intel laptop to use as my linux machine.
