| | * | | | | | | | | | | ath9k_htc: introduce support for different fw versionsOleksij Rempel2015-09-18

Which is ok so far we have only one fw version (1.3). After we realised new fw 1.4, we faced compatibility problem which was decided to solve by firmware name and location: - new firmware is located now in firmware/ath9k_htc/htc_[9271|7010]-1.4.0.fw - old version 1.3 should be on old place, so old kernel have no issues with it. - new kernels including this patch should be able to try different supported (min..max) fw version. - new kernel should be able to support old fw location too. At least for now. At same time this patch will add new module option which should allow user to play with development fw version without replacing stable one. If user will set “ath9k_htc use_dev_fw=1” module will try to find firmware/ath9k_htc/htc_[9271|7010]-1.dev.0.fw first and if it fails, use stable version: for example...1.4.0.fw.

Also, there is no need to make this driver user selectable, because it is already selected by all drivers that need it. This changes the Kconfig file to select the correct library, and to make the option silent.

In this case, the reboot is not detected by the loop on efx_mcdi_poll_reboot(), so prepare for recovery from an MC reboot anyway. When this codepath is run, the MC has always just rebooted, so this recovery is valid. The loop on efx_mcdi_poll_reboot() is still required for other MC reboot cases, so that actions in response to an MC reboot are performed, such as clearing locally calculated statistics. Siena NICs are unaffected by this change as the above scenario does not apply. Signed-off-by: Shradha Shah <sshah@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

We remove the locking for irq resources by enable/disable irq and allocate directly some heap buffer at isr. We have still a enable/disable irq path but this is for level-triggered irq's which need to be disabled until spi_async clear the irq line. There is usually a little race condition between "irq line cleared" and "enable_irq". When in this time a edge triggered irq arrived, we will not recognize this interrupt. This case can't happend at at86rf230. The reason is that we unmask TRX_END irq's only which indicates a transmit or receive completion, which depends on the current state. On Transmit: TRX_END arrived and transceiver is in TX_ARET_ON state again, in this state no other TRX_END can happen until we leave the state. On Receive: This is protected with the RX_SAFE_MODE bit which leaves the transceiver in RX_AACK_BUSY until we readed the framebuffer. In this state no other TRX_END can happen. Tested with RPi where I first detected issues between edge/level irq's. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

Lets remove the couple traces of modularity so that when reading the driver there is no doubt it is builtin-only. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

It's entirely too easy to miss a reset because none of the bits are sticky. By the time the VF driver reads the register, the reset may have been processed and cleaned up by the PF driver, leaving the register in the same state that it was before the reset. Instead, detect a reset with the VF_ARQLEN register. When the VF is reset, the enable bit in this register is cleared, and it stays cleared until the VF driver processes the reset and re-enables the admin queue. Because we now deal with multiple registers in the reset and watchdog tasks, rename the rstat_val variable to reg_val.
