Acked-by: Guchun Chen <guchun.chen@xxxxxxx> Regards, Guchun -----Original Message----- From: amd-gfx <amd-gfx-bounces@xxxxxxxxxxxxxxxxxxxxx> On Behalf Of Alex Deucher Sent: Wednesday, February 23, 2022 12:08 AM To: amd-gfx@xxxxxxxxxxxxxxxxxxxxx; bhelgaas@xxxxxxxxxx; linux-pci@xxxxxxxxxxxxxxx Cc: Deucher, Alexander <Alexander.Deucher@xxxxxxx> Subject: [PATCH] PCI: Apply quirk_amd_harvest_no_ats to all navi10 and 14 asics There are enough vbios escapes without the proper workaround that some users still hit this. MS never productized ATS on windows so OEM platforms that were windows only didn't always validate ATS. The advantages of ATS are not worth it compared to the potential instabilities on harvested boards. Just disable ATS on all navi10 and 14 boards.
