AMD RadeonHD Version 1.0-RC4:
The RadeonHD graphics driver provides full 2D graphics acceleration for Radeon HD graphics cards. It supports everything from the Radeon HD 2000 series (R600 chipsets) through to the Radeon HD 7000 series. It also supports the older Radeon X1300-X1950 graphics cards (R500 chipsets), although these are not recommended. Apart from the usual improvements the update fixed a couple of pesky problems which were effecting some graphics cards.
Version 1.0-RC4 incorporates the following changes:
- Resolved an issue which could cause a deadlock when the RadeonHD_RM.resource's memory management was used (locked up RHDRMTest2)
- WaitIdle() now locks the command processor to ensure that it's idle and prevents a very rare infinite loop from occurring
- Now lower Evergreen+ clocks down to initial values for initialisation after a soft-reset (helps with some tricky RadeonHD cards)
- Fixed a bug in the code to get the graphics card's ROM
- Disabled compositing for 16-bit target bitmaps/screens with Radeon HD7xxx series cards (did not work correctly due to a hardware limitation of these cards)
