Hi Yogesh: http://oorja.iind.intel.com/mediawiki/index.php/Flatland can you also try the flatland on this page. For AOSP flatland, yes, the EGL patch may solve the issue. However, I met one case that the batch buffer is empty just at the swapbuffer (glfush is just called before that), then

This can be dropped. I'm running with egl patch alone and things seem fine. Zhongmin, please comment if you don’t think so. > -Original Message- > From: mesa-dev [mailto:mesa-dev-boun...@lists.freedesktop.org] On Behalf > Of Marathe, Yogesh > Sent: Friday, August 4, 2017 9:18 PM > >

Hi Zhongmin, Is the issue resolved by the EGL patch alone? Worth sticking with that for now? I think this patch will cause some noticeable overhead - see below for details. On 21 July 2017 at 04:08, Zhongmin Wu wrote: > Always save the last fence in the brw context when

Always save the last fence in the brw context when flushing buffer. If the buffer is nothing to be flushed, then return the last fence when asked for. Change-Id: Ic47035bcd1a27e402609afd9e2d1e3972548b97d Signed-off-by: Zhongmin Wu ---
