From 741ddae6c4c19bf2212ca318777320ae4f76c714 Mon Sep 17 00:00:00 2001 From: Frederic Barrat Date: Tue, 23 Jan 2018 12:31:46 +0100 Subject: [PATCH] cxl: Remove support for "Processing accelerators" class The cxl driver currently declares in its table of supported PCI devices the class "Processing accelerators". Therefore it may be called to probe for opencapi devices, which generates errors, as the config space of a cxl device is not compatible with opencapi. So remove support for the generic class, as we now have (at least) two drivers for devices of the same class. Most cxl devices are FPGAs with a PSL which will show a known device ID of 0x477. Other devices are really supported by the cxlflash driver and are already listed in the table. So removing the class is expected to go unnoticed.
