By default, if a device is in the denylist, the probe of vfio-pci fails. If a user wants to use a device in the denylist, he needs to disable the full denylist providing the option disable_denylist=1 at the load of vfio-pci or specifying that parameter in a config file in /etc/modprobe.d. This series also moves the device ids definitions present in the qat driver to linux/pci_ids.h since they will be shared between the vfio-pci and the qat drivers and replaces the custom ADF_SYSTEM_DEVICE macro with PCI_VDEVICE. The series is applicable to Herbert's tree. Patches 1 to 3 apply also to Alex's tree (next). Patches 4 and 5 are optional and can be applied at a later stage. Changes from v2: - Renamed blocklist in denylist - Patch #2: reworded module parameter description to clarify why a device is in the denylist - Patch #2: reworded warning that occurs when denylist is enabled and device is present in that list Changes from v1: - Reworked commit messages: Patches #1, #2 and #3: capitalized first character after column to comply to subject line convention Patch #3: Capitalized QAT acronym and added link and doc number for document "Intel® QuickAssist Technology (Intel® QAT) Software for Linux" Giovanni Cabiddu (5): PCI: Add Intel QuickAssist device IDs vfio/pci: Add device denylist vfio/pci: Add QAT devices to denylist crypto: qat - replace device ids defines crypto: qat - use PCI_VDEVICE drivers/crypto/qat/qat_c3xxx/adf_drv.c | 11 ++--- drivers/crypto/qat/qat_c3xxxvf/adf_drv.c | 11 ++--- drivers/crypto/qat/qat_c62x/adf_drv.c | 11 ++--- drivers/crypto/qat/qat_c62xvf/adf_drv.c | 11 ++--- .../crypto/qat/qat_common/adf_accel_devices.h | 6 --- drivers/crypto/qat/qat_common/qat_hal.c | 7 +-- drivers/crypto/qat/qat_common/qat_uclo.c | 9 ++-- drivers/crypto/qat/qat_dh895xcc/adf_drv.c | 11 ++--- drivers/crypto/qat/qat_dh895xccvf/adf_drv.c | 11 ++--- drivers/vfio/pci/vfio_pci.c | 48 +++++++++++++++++++ include/linux/pci_ids.h | 6 +++ 11 files changed, 87 insertions(+), 55 deletions(-) -- 2.26.2
