Re: Does linux-linaro support kernel page size bigger than 4K?

2013-09-09 Thread Subash Patel
Hi Xu, Qiang, I doubt if it has anything todo with linaro kernel. ARM linux code is programming the page sizes as 4K. >From my experience playing with the page tables, you will have to fiddle with the section size and page size programming in the ARM mmu initialization. Depending on kernel split,

2012-04-12 Thread Subash Patel
Hello, I am interested to know if anyone from Linaro has attempted using Flyswatter2 on origen board. I am trying to use openocd for origen board, and found issues as early as in reading tapid. Any pointers/help on this is appreciated. Note: I saw some discussion on this in irc-logs, but I c

No. We dont have this AFAIK. Is there a specific need to have a separate branch for exynos4? Regards, Subash Samsung - SISO On 09/22/2011 12:21 AM, Zach Pfeffer wrote: Mike asked me about this in IRC. Figured I'd spin up a thread. ___ linaro-dev m

2011-02-08 Thread Subash Patel
In the reference architecture in ppt, we can directly wait for the RSZ interrupt, if we configure the hardware pipe. It was my mis-understanding as each of those hardware blocks can deliver interrupts too. In that way ARM needs to just work at finished frame, like forward it to the display or co
