Updating rd_offset prematurely can lead to the host accessing an uninitialized or incomplete element, resulting in data corruption. Invoke the buffer write before updating rd_offset to ensure the element is fully written before signaling its availability.

RE: Patch "EDAC/igen6: Skip absent memory controllers" has been added to the 6.15-stable tree

by Zhuo, Qiuxu

Hi Sasha, > From: Sasha Levin <sashal(a)kernel.org> > [...] > Subject: Patch "EDAC/igen6: Skip absent memory controllers" has been added > to the 6.15-stable tree > This patch fixes the issue of the igen6_edac driver mistakenly enumerating the absent memory controllers, but it may also trigger a panic. So, please either do not backport this patch or backport it together with the patch [1], which has been queued in the RAS edac-drivers branch.

But if the error occurs in the first frames, before setup the capture queue, there is no chance to schedule device_run(), and there may be no capture to mark error. So we need to drop this buffer with error flag, and make the decoding can continue.
