Radeon DRM Gets New Information Ioctl Queries

[Awesomeness]

How on earth do they get any development done without a proper patch submit and review tool? Sending patches to mailing lists is so 1990s?

the main difference between windows and linux in this aspect, is that manufacturers include their crappy modifications in their crappy drivers where in linux devs have to figure out ...

That point is sadly so true.
Vendor specific extensions and such nonsense. This is also why a lot of chipmakers tell W32 users to go to the laptop / mobo website and get drivers from there. Of course those drivers are rarely updated and often limited to Windows and then even a specific Windows version. Don't want Vista on your laptop? Bad luck.
And that was also a problem for many complaints towards some HW on Linux that would just run flawed.
But also generally some chipmakes (without any vendor mods) can hide workarounds for HW bugs in their blob drivers while people then start to blame Linux for not running well on a HW. But this way a lot of nasty bugs was discovered... (e.g. some AS Media PCIe to PCI bridge some time ago. looked like they never actually tested that thing in action before soldering it to thousands of mainboards)

And then you still have those chips from normally okay chipmanufacturers that are custom made for one series of mainboards/laptops. Nobody seems to feel responsible for these chips. Sucks.

On topic: Thumbs up for the code addition. Maybe in the future this could be exposed via proc or sysfs as Michael mentioned? Would be very nice.

They're generated from branches by git-send-email in a standard format, and the commits in question can be pulled, examined and fiddled with using whatever review tool you like.
Very different from just mailing random patches about like the '90s; the commits already belong to a properly organised repo elsewhere. The list is just a place to comment on patches, not the sole method of organising and obtaining them.
