Pinned pages are not properly accounted particularly when mapping error occurs on IOTLB update. Clean up dangling pinned pages for the error path. As the inflight pinned pages, specifically for memory region that strides across multiple chunks, would need more than one free page for book keeping and accounting. For simplicity, pin pages for all memory in the IOVA range in one go rather than have

Hi David, Why this patch doesn't get picked in the last 4 months? Maybe the subject is not clear, but this is an iproute2 patch. Would it be possible to merge at your earliest convenience? PS, adding my R-b to the patch. Thanks, -Siwei On Sat, May 13, 2023 at 12:42?AM Shannon Nelson <shannon.nelson at amd.com> wrote: > > From: Allen Hubbe <allen.hubbe at amd.com>

When I repeated restarting VM or define and undefined VM during my recently test, memory leakage of xend is detected. Our elementary conclusion is that the python memory management mechanism causes this problem, but I do not know how to further locate the exact lines. Can anybody here give me any suggestions? Thx.

Hi, Was this ever resolved? I'm curious, I'm also in a situation where there may be many (very many) JITted functions over the history of an application (which may be running for many days) Thanks On Mar 20, 2009, at 7:34 AM, George Giorgidze wrote: > Hi, > > In my application I am JITing thousands of functions, though I am > doing it sequantially and running only
