Subject: Re: [PATCH v17 02/12] PCI/TPH: Fix tph_enabled concurrent update race by bitfield packing
Date: Tue, 16 Jun 2026 10:55:33 +0000 [thread overview]
Message-ID: <20260616105534.241301F000E9@smtp.kernel.org> (raw)
In-Reply-To: <20260616104621.41915-3-fengchengwen@huawei.com>
> Split tph_enabled from shared pci_dev bitfield into spare bit of tph_cap's
> u16: tph_cap is immutable post-enumeration (15 bits for offset), remaining
> 1 bit stores tph_enabled. Removes cross-bitfield concurrent write hazards
> highlighted by Sashiko after VFIO TPH exposure. No functional changes.
