Hi all,
We had a discussion yesterday regarding ways in which linaro can assist
V4L2 development. One topic was that of sorting out memory providers like
GEM and HWMEM.
Today I learned of yet another one: UMP from ARM.

There are comments for your System MMU driver below.
Please take into account that this was an initial version of our SYSMMU

Dear Jonghun,
It's also helpful to explain what's the original purpose of UMP (for
GPU, MALI) and what's the goal of UMP usage for multimedia stack.
Especially, what's the final goal of UMP from LSI.
Also consider the previous GPU memory management program, e.g., SGX.
Thank you,

user wants fixed 'da' or not. At the same time, it doesn't disallow address

Currently IOVMM driver sets IOVMF_DA_FIXED/IOVMF_DA_ANON flags according
to input 'da' address when mapping memory:
da == 0: IOVMF_DA_ANON
da != 0: IOVMF_DA_FIXED
It prevents IOMMU to map first page with fixed 'da'. To avoid such
issue, IOVMM will not automatically set IOVMF_DA_FIXED. It should

hi!
i was able to find an antenna position/orientation that allows good quality for
7 stations with SNR above 0x78... *wag tail*
up to 4 stations with just one stick at the same time... *w00t*
so it is not as urgent as before that the analog audio part works...
thx...

Hi,
Can anyone pls confirm this is fixed in the latest v4l driver? I am using the

My feeling is that tuning is not working properly because of this error.
