From 0be97436bf249503b2c5898e7459744962b70f15 Mon Sep 17 00:00:00 2001 From: Sunil Khatri Date: Tue, 12 May 2026 16:00:18 +0530 Subject: [PATCH] drm/amdgpu/userq: update the vm task info during signal ioctl MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Pagefaults does not have process information correctly populated as vm->task is not set during vm_init but should be updated while real submission. So setting that up during signal_ioctl to get the correct submission process details.
