The radeon driver should have the correct bits for indirect MC access on RS690/740 and RS600. Note that RS690/740 and RS600 are different WRT MC setup. See: RADEONINMC() RADEONOUTMC() radeon_get_mc_idle() in radeon_driver.c for the relevant regs and bits.

Alex, What about the difference between MMIO register space used by radeon driver, and PCIe register space used by radeonhd? Is there any way to convert from the first to the second and vice-versa? Is it relevant at all?
best regards,
Dariem
Forget the previous message, now I'm seeing radeonhd source code and I can see _RHDWriteMC() uses RHDRegWrite() to write MC for RS600, which is an alias for MMIO_OUT32() with some level of indirection ;-) . Thanks anyway.

Dariem, I'm not a programmer, but I have a laptop with the RS690M and I'm happy to test patches, etc. if you need help there. -- David C. Rankin, J.D.,P.E.
