Hi,<div><br></div><div>I have updated slides for CMA and DMA_Buffer.</div><div>I hope it will make more clear why DMA_Buffer is needed.</div><div><br></div><div>Yes CMA grab memory at boot time, mark it with MIGRATE_CMA and give it back to the system.</div>
<div><br></div><div>I don&#39;t know what happen when the system don&#39;t have enough space to allocate unmovable pages but from the patches comments it is clear that CMA memory can&#39;t be used for unmovable allocations. Maybe Marek can answer to this question ?</div>
<div><br></div><div>Additional question:</div><div>- where can we found git tree with CMA, DMA_Buf and DMA IOMMU ?</div><div><br></div><div><br></div><div>Regards,</div><div>Benjamin</div><div><div class="gmail_quote"><br>
