2011-06-12net: DM9000: Add support for byte EEPROM accessBen Dooks1-6/+20
Given many versions of ethtool's reluctance to do anything other than byte accesses to the EEPROM interface, it is easier to update the driver to support byte accesses so that all the ethtool versions that have been observed in Debian can write the EEPROM.

2011-06-02net: dm9000: Get the chip in a known good state before enabling interruptsMark Brown1-3/+3
Currently the DM9000 driver requests the primary interrupt before it resets the chip and puts it into a known good state. This means that if the chip is asserting interrupt for some reason we can end up with a screaming IRQ that the interrupt handler is unable to deal with. Avoid this by only requesting the interrupt after we've reset the chip so we know what state it's in. This started manifesting itself on one of my boards in the past month or so, I suspect as a result of some core infrastructure changes removing some form of mitigation against bad behaviour here, even when things boot it seems that the new code brings the interface up more quickly.

2011-02-24DM9000B: Fix PHY power for network down/upHenry Nestler1-3/+4
DM9000 revision B needs 1 ms delay after PHY power-on. PHY must be powered on by writing 0 into register DM9000_GPR before all other settings will change (see Davicom spec and example code). Remember, that register DM9000_GPR was not changed by reset sequence. Without this fix the FIFO is out of sync and sends wrong data after sequence of "ifconfig ethX down ; ifconfig ethX up".

dm9000_set_rx_csum and dm9000_hash_table are called from atomic context (in dm9000_init_dm9000), and from non-atomic context (via ethtool_ops and net_device_ops respectively).

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo1-0/+1
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

Add support for Wake on LAN (WOL) reception and waking the device up from this signal via the ethtool interface. Currently we are only supporting the magic-packet variant of wakeup. WOL is enabled by specifying a second interrupt resource to the driver which indicates where the interrupt for the WOL is being signalled. This then enables the necessary ethtool calls to leave the device in a state to receive WOL frames when going into suspend.

2009-03-23dm9000: locking bugfixDavid Brownell1-2/+4
This fixes a locking bug in the dm9000 driver. It calls request_irq() without setting IRQF_DISABLED ... which is correct for handlers that support IRQ sharing, since that behavior is not guaranteed for shared IRQs. However, its IRQ handler then wrongly assumes that IRQs are blocked. So the fix just uses the right spinlock primitives in the IRQ handler. NOTE: this is a classic example of the type of bug which lockdep currently masks by forcibly setting IRQF_DISABLED on IRQ handlers that did not request that flag.

2008-11-13netdevice: safe convert to netdev_priv() #part-2Wang Chen1-16/+16
We have some reasons to kill netdev->priv: 1. netdev->priv is equal to netdev_priv(). 2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously netdev_priv() is more flexible than netdev->priv. But we cann't kill netdev->priv, because so many drivers reference to it directly. This patch is a safe convert for netdev->priv to netdev_priv(netdev). Since all of the netdev->priv is only for read. But it is too big to be sent in one mail. I split it to 4 parts and make every part smaller than 100,000 bytes, which is max size allowed by vger.
