<div>Hi All, </div> <div> </div> <div> I have sent an invitation for 3pm UTC Monday 7th March to have a discussion on things that can be explored/worked upon in Linaro related to v4l2 support.The idea is to come out with concrete activities that can be targeted in Linaro MM WG to address this topic.</div> <div> </div> <div>If any body is unhappy with time please let me know.I tried to take care of US,Europe and India time zones.</div> <div>Also please forward the invitation to anybody I have missed out on</div> <div> </div> <div>Thanks</div> <div>Sachin<br><br></div> <div class="gmail_quote">On Tue, Mar 1, 2011 at 4:21 PM, Marek Szyprowski <span dir="ltr"><<a href="mailto:m.szyprowski@samsung.com">m.szyprowski@samsung.com</a>></span> wrote:<br> <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">Hello,<br> <div class="im"><br>On Tuesday, March 01, 2011 11:26 AM Edward Hervey wrote:<br><br>> On Mon, 2011-02-28 at 09:50 +0100, Marek Szyprowski wrote:<br>> > Hello,<br>> [...]<br>> ><br>> > I'm not sure that highmem is the right solution.
