Hello All,<div>I am able to fix the 3M memory leak. 1M as explained already and the other 2M was because of my mistake -one extra thread that I had launched and was not getting freed.</div><div>However, I still see few kBs ~132kB of memory leaked in every 2-3 iterations of Init-Term Xserver. Note: In some iterations of Init-TermX there is 0 memory leak and some there is a chunk of 132kB. </div>
<div>Also, I am still stuck with failure(Device or resource busy) is ioctl(fd, DISALLOCATE, vtno) in LinuxFini(). I doubt this for the 132kB leak. Can anyone help me out with this? Note: This ioctl failure happens only on target board (ARM) and not on x86.</div>
<div>Any inputs related to above would be very useful to me.</div><div>Thanks again,</div><div>Vrushali</div><div><br><div class="gmail_quote">On Tue, Nov 2, 2010 at 9:48 AM, vrushali shinde <span dir="ltr"><<a href="mailto:vrushali1201@gmail.com">vrushali1201@gmail.com</a>></span> wrote:<br>

<div>Also I did get some success in freeing 1M out of 3M memory that was leaked. This is achieved by calling mieqFini() at termination of Xserver. This function internally calls FreeEventlist() which frees the 1M memory allocated in InitEventList().</div>

</div>Kdrive development is practically dead. We just have some few people working<br>
on Xephyr backend and the other hw servers are due to be extinct. To<br>
substitute kdrive + fbdev you can try Xorg + fbdev driver which should be all<br>
the work you need.<br>
