AmigaOS 4.1: Grafikkartentreiber RadeonHD V5.20 für Sam460
Die RadeonHD-Treibersoftware ist ein Grafiktreiber für RadeonHD-Grafikkarten für AmigaOS 4.1 (amiga-news.de berichtete). Die Version 5 unterstützt nur noch "Southern Islands"-Karten (HD7000-Serie), bietet aber hardwarebeschleunigte Videodekodierung (Enhancer Software 2.2 erforderlich). Für den Sam460 wurde nun die neue Version 5.20 veröffentlicht. Die Änderungen:
- Fixed a potential crash in the find card code when the card is already in
use
- Fixed an infinite loop in code to get PCIe speed capabilities, which would
trigger if the parent PCIe device isn't the root controller
- Disabled GART for the Sam460 again (was accidentally enabled)
- The usleep() threshold for using the timer device was broken a while ago.
FIXED
- Rewrote usleep() so it no longer needs to open/close the timer device
every time there's a longer delay (lowers overhead)
- Now skips attempting to initialize the card altogether if the card is
already in use
- Fixed a potential crash if initializing the driver failed
- Enabled the UVD interrupt (trap handler)
- Fixed interrupt handling for the Sam460. Caching on PCIe reads from VRAM
was causing the interrupt handler to read stale data, resulting in missed
interrupts which, in turn, causes a complete freeze. Added fallback and
workaround code
