Either you did not describe the problem accurately, or the proposed solution is wrong. My answer to your original question would be, use "MapIoMem" from driver or "map_io_mem" from inside kernel. An example can be found in drivers that use memory mapped I/O such as i8254x network...

"hdaudio" is ok for me, driver works on many chips of different brands
"ac97" is a problem for me, this driver works only on intel chips with AC97, not on VIA AC97 just to give an example. maybe "intel97" ?

I think that need modify a scheduler algorithm - it need to switch to user threads with waiting sockets just after system threads is ends Hmm, not sure, any idea about how much time we currently 'lose' ? My driver no downloads foreign packets (multicast/broadcast/promiscuous recive is disabled). Al...

Yes, it's a known issue. Some reasons: 1. TCP implementation is unfinished. "At the same time, download freezes are observed in the download progress in Dl." for example is an effect of the congestion control algorithm. 2. Nothing is really optimized or "tuned" for performance so...

hidnplayr , Can I choose card? Or KolibriOS use first detected card? KolibriOS will use all available cards by default. Only IPv4 routing is not so smart and may prefer first detected one to contact router (eg to the internet) If you remove "NETCFG A" from autorun.dat, you can load driver...

Maybe I should implement working with all ahci controllers, not only first one.

I too would appreciate that :D

I have for example some PCI add-on cards that would otherwise give trouble, and probably some untested hardware with multiple AHCI controllers as well ;)

Thank you for testing. As far as I understand problem is that this controller at first initialized as IDE and then as AHCI, right? Btw, does it work properly after that? I'm not sure why this controller doesn't behave as the others (except that it's quite old :) ) I tried all different related sett...

I tested on some systems I have laying around, every time with the same hard drive. (And sometimes more..) Tested by reading a PDF from the drive every time. All but one good so far! It appears the ICH6 SATA controller is a sheep in wolves clothes: "8086 2651 00 1f 02 03 01 01 8f 02 09 Intel Co...

Yes, Attansic seems to have been bought by Atheros which seems to have been bought by Qualcomm.
But I don't care about the brand name when making a driver, more about the architecture of the chip ;)

Anyway, it seems architecturally different enough to put in a separate driver.

It seems I made a typing error :) 1969:2048 it is indeed.
Anyway, I asked to check if it is possible to add support in AR81XX driver, but it's not so easy for this device, sorry.
