| 2020-09-29 | net: e100: Remove in_interrupt() usage and pointless GFP_ATOMIC allocation | Sebastian Andrzej Siewior | |
| e100_hw_init() invokes e100_self_test() only if in_interrupt() returns false as e100_self_test() uses msleep() which requires sleepable task context. The in_interrupt() check is incomplete because in_interrupt() cannot catch callers from contexts which have just preemption or interrupts disabled. e100_hw_init() is invoked from: - e100_loopback_test() which clearly is sleepable task context as the function uses msleep() itself. - e100_up() which clearly is sleepable task context as well because it invokes e100_alloc_cbs() abd request_irq() which both require sleepable task context due to GFP_KERNEL allocations and mutex_lock() operations. Remove the pointless in_interrupt() check. As a side effect of this analysis it turned out that e100_rx_alloc_list() which is only invoked from e100_loopback_test() and e100_up() pointlessly uses a GFP_ATOMIC allocation. The next invoked function e100_alloc_cbs() is using GFP_KERNEL already. Change the allocation mode in e100_rx_alloc_list() to GFP_KERNEL as well.

| 2020-09-25 | intel: handle unused assignments | Jesse Brandeburg | |
| Remove variables that were storing a return value from a register read or other read, where the return value wasn't used. Those conversions to remove the lvalue of the assignment should be safe because the readl memory mapped reads are marked volatile and should not be optimized out without an lvalue (I suspect a very long time ago this wasn't guaranteed as it is today). These changes are part of a separate patch to make it easier to review.

| 2020-09-25 | intel-ethernet: clean up W=1 warnings in kdoc | Jesse Brandeburg | |
| This takes care of all of the trivial W=1 fixes in the Intel Ethernet drivers, which allows developers and maintainers to build more of the networking tree with more complete warning checks. There are three classes of kdoc warnings fixed: - cannot understand function prototype: 'x' - Excess function parameter 'x' description in 'y' - Function parameter or member 'x' not described in 'y' All of the changes were trivial comment updates on function headers. Inspired by Lee Jones' series of wireless work to do the same.

| 2020-07-30 | e100: use generic power management | Vaibhav Gupta | |
| With legacy PM hooks, it was the responsibility of a driver to manage PCI states and also the device's power state. The generic approach is to let PCI core handle the work. e100_suspend() calls __e100_shutdown() to perform intermediate tasks. __e100_shutdown() calls pci_save_state() which is not recommended. e100_suspend() also calls __e100_power_off() which is calling PCI helper functions, pci_prepare_to_sleep(), pci_set_power_state(), along with pci_wake_from_d3(...,false). Hence, the functin call is removed and wol is disabled as earlier using device_wakeup_disable(). Compile-tested only.

| 2020-06-25 | net/intel: remove driver versions from Intel drivers | Jeff Kirsher | |
| As with other networking drivers, remove the unnecessary driver version from the Intel drivers. The ethtool driver information and module version will then report the kernel version instead. For ixgbe, i40e and ice drivers, the driver passes the driver version to the firmware to confirm that we are up and running. So we now pass the value of UTS_RELEASE to the firmware. This adminq call is required per the HAS document. The Device then sends an indication to the BMC that the PF driver is present. This is done using Host NC Driver Status Indication in NC-SI Get Link command or via the Host Network Controller Driver Status Change AEN. What the BMC may do with this information is implementation-dependent, but this is a standard NC-SI 1.1 command we honor per the HAS.

| 2018-11-21 | ethernet/intel: consolidate NAPI and NAPI exit | Jesse Brandeburg | |
| While reviewing code, I noticed that Eric Dumazet recommends that drivers check the return code of napi_complete_done, and use that to decide to enable interrupts or not when exiting poll. One of the Intel drivers was already fixed (ixgbe). Upon looking at the Intel drivers as a whole, we are handling our polling and NAPI exit in a few different ways based on whether we have multiqueue and whether we have Tx cleanup included. Several drivers had the bug of exiting NAPI with return 0, which appears to mess up the accounting in the stack. Consolidate all the NAPI routines to do best known way of exiting and to just mostly look like each other. 1) check return code of napi_complete_done to control interrupt enable 2) return the actual amount of work done. 3) return budget immediately if need NAPI poll again Tested the changes on e1000e with a high interrupt rate set, and it shows about an 8% reduction in the CPU utilization when busy polling because we aren't re-enabling interrupts when we're about to be polled.

| The __dev* removal patches for the network drivers ended up messing up the function prototypes for a bunch of drivers. This patch fixes all of them back up to be properly aligned. Bonus is that this almost removes 100 lines of code, always a nice surprise. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: David S. Miller <davem@davemloft.net> | |||

| 2012-07-19 | net: e100: ucode is optional in some cases | Bjørn Mork | |
| commit 9ac32e1b firmware: convert e100 driver to request_firmware() did a straight conversion of the in-driver ucode to external files. This introduced the possibility of the driver failing to enable an interface due to missing ucode. There was no evaluation of the importance of the ucode at the time. Based on comments in earlier versions of this driver, and in the source code for the FreeBSD fxp driver, we can assume that the ucode implements the "CPU Cycle Saver" feature on supported adapters. Although generally wanted, this is an optional feature. The ucode source is not available, preventing it from being included in free distributions. This creates unnecessary problems for the end users. Doing a network install based on a free distribution installer requires the user to download and insert the ucode into the installer. Making the ucode optional when possible | |||
