From 3936bbdf9a2e9233875f850c7576c79d06add261 Mon Sep 17 00:00:00 2001 From: Vincent Fu Date: Fri, 3 May 2024 13:50:04 -0400 Subject: [PATCH] hw/nvme: fix number of PIDs for FDP RUH update The number of PIDs is in the upper 16 bits of cdw10. So we need to right-shift by 16 bits instead of only a single bit.
