From 23a5b8bb022c1e071ca91b1a9c10f0ad6a0966e9 Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Thu, 27 Apr 2023 00:33:36 -0500 Subject: x86/amd_nb: Add PCI ID for family 19h model 78h Commit 310e782a99c7 ("platform/x86/amd: pmc: Utilize SMN index 0 for driver probe") switched to using amd_smn_read() which relies upon the misc PCI ID used by DF function 3 being included in a table. The ID for model 78h is missing in that table, so amd_smn_read() doesn't work. Add the missing ID into amd_nb, restoring s2idle on this system.

We may need to free the ctxt as well. As freeing the ctxt is all that ->xpo_release_rqst() does, we repurpose it to explicit do that even when the ctxt is not stored in an rqst. So we now have ->xpo_release_ctxt() which is given an xprt and a ctxt, which may have been taken either from an rqst or from a dreq. The caller is now responsible for clearing that pointer after the call to ->xpo_release_ctxt. We also clear dr->xprt_ctxt when the ctxt is moved into a new rqst when revisiting a deferred request. This ensures there is only one pointer to the ctxt, so the risk of double freeing in future is reduced. The new code in svc_xprt_release which releases both the ctxt and any rq_deferred depends on this.
