2018-12-18mlxsw: core: Increase timeout during firmware flash processShalom Toledo1-0/+3
During the firmware flash process, some of the EMADs get timed out, which causes the driver to send them again with a limit of 5 retries. There are some situations in which 5 retries is not enough and the EMAD access fails. If the failed EMAD was related to the flashing process, the driver fails the flashing. The reason for these timeouts during firmware flashing is cache misses in the CPU running the firmware. In case the CPU needs to fetch instructions from the flash when a firmware is flashed, it needs to wait for the flashing to complete. Since flashing takes time, it is possible for pending EMADs to timeout. Fix by increasing EMADs' timeout while flashing firmware.

2018-12-03mlxsw: spectrum: Load firmware version based on devlink parameterShalom Toledo1-0/+2
Load firmware version based on 'fw_load_policy' devlink parameter. The driver supports these two options: * DEVLINK_PARAM_FW_LOAD_POLICY_VALUE_DRIVER (0) Default, load firmware version preferred by the driver * DEVLINK_PARAM_FW_LOAD_POLICY_VALUE_FLASH (1) Load firmware currently stored in flash The second option, 'flash', allow the device to run with different firmware version than preferred by the driver for testing and/or debugging purposes. For example, testing a firmware bug fix.

2018-10-17mlxsw: core: Fix use-after-free when flashing firmware during initIdo Schimmel1-0/+4
When the switch driver (e.g., mlxsw_spectrum) determines it needs to flash a new firmware version it resets the ASIC after the flashing process. The bus driver (e.g., mlxsw_pci) then registers itself again with mlxsw_core which means (among other things) that the device registers itself again with the hwmon subsystem again. Since the device was registered with the hwmon subsystem using devm_hwmon_device_register_with_groups(), then the old hwmon device (registered before the flashing) was never unregistered and was referencing stale data, resulting in a use-after free. Fix by removing reliance on device managed APIs in mlxsw_hwmon_init().

2018-05-29mlxsw: pci: Utilize MRSR register to perform FW resetJiri Pirko1-1/+1
So far, the PCI BAR0 register is used for triggering FW reset. However, that is a legacy attitude and it is recommended to use MRSR to perform reset instead. So do that. Move the reset into init() function as the cmd interface needs to be used. With that, IRQ initialization needs to be moved as well.

Note that we can't simply convert the current workqueue to be ordered, as EMADs re-transmissions are also processed in deferred work. Later on, we can migrate other work items to this workqueue, such as FDB notification processing and nexthop resolution, since they all take the same lock anyway.

So far, mlxsw_pci.ko is the module that registers PCI table for all drivers (spectrum and switchx2). That is problematic for example with dracut. Since mlxsw_spectrum.ko and mlxsw_switchx2.ko are loaded dynamically from within mlxsw_core.ko, dracut does not have track of them and avoids them from being included in initramfs. So make this in an ordinary way and define the PCI tables in individual driver modules, so it can be properly loaded and included in dracut initramfs image. As a side effect, this patch could remove no longer necessary driver "kind" strings which were used to link PCI ids with individual mlxsw drivers.
