However, theSwitchtec device advertises a special management endpoint with a separatePCI function address and class code. This endpoint enables some additionalfunctionality which includes: * Packet and Byte Counters * Switch Firmware Upgrades * Event and Error logs * Querying port link status * Custom user firmware commandsAdd a switchtec kernel module which provides PCI driver that exposes a chardevice. The char device provides userspace access to this interfacethrough read, write and (optionally) poll calls.A userspace tool and library which utilizes this interface is availableat [1]. This tool takes inspiration (and borrows some code) fromnvme-cli [2]. The tool is largely complete at this time but additionalfeatures may be added in the future.[1] https://github.com/sbates130272/switchtec-user[2] https://github.com/linux-nvme/nvme-cli[Dan Carpenter <dan.carpenter@oracle.com>: don't invert error codes][Christophe JAILLET <christophe.jaillet@wanadoo.fr>: fixswitchtec_dev_open() error handling]Tested-by: Krishna Dhulipala <krishnad@fb.com>Signed-off-by: Logan Gunthorpe <logang@deltatee.com>Signed-off-by: Stephen Bates <stephen.bates@microsemi.com>Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>Reviewed-by: Wei Zhang <wzhang@fb.com>Reviewed-by: Jens Axboe <axboe@fb.com>Reviewed-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> List of files: /linux-6.15/drivers/pci/switch/Makefile Tue, 07 Mar 2017 00:30:54 +0000 Logan Gunthorpe <logang@deltatee.com>
