| | | | | | | | | | | | | | | | | | | | | | | | | | Skge devices installed on some Gigabyte motherboards are not able to perform 64 dma correctly due to board PCI implementation, so limit DMA to 32bit if such boards are detected.

| * include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+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.

* skge: use unique IRQ nameMichal Schmidt2009-10-021-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most network drivers request their IRQ when the interface is activated. skge does it in ->probe() instead, because it can work with two-port cards where the two net_devices use the same IRQ. This works fine most of the time, except in some situations when the interface gets renamed. Consider this example: 1. modprobe skge The card is detected as eth0 and requests IRQ 17. Directory /proc/irq/17/eth0 is created. 2. There is an udev rule which says this interface should be called eth1, so udev renames eth0 -> eth1. 3. modprobe 8139too The Realtek card is detected as eth0. It will be using IRQ 17 too. 4. ip link set eth0 up Now 8139too requests IRQ 17. The result is: WARNING: at fs/proc/generic.c:590 proc_register ... proc_dir_entry '17/eth0' already registered ... And "ls /proc/irq/17" shows two subdirectories, both called eth0. Fix it by using a unique name for skge's IRQ, based on the PCI address. The naming from the example then looks like this: $ grep skge /proc/interrupts 17: 169 IO-APIC-fasteoi skge@pci:0000:00:0a.0, eth0 irqbalance daemon will have to be taught to recognize "skge@" as an Ethernet interrupt. This will be a one-liner addition in classify.c. I will send a patch to irqbalance if this change is accepted.

* skge: fix occasional BUG during MTU changeMichal Schmidt2009-04-151-2/+2
| | | | | | | | | | | | | | | | | | The BUG_ON(skge->tx_ring.to_use != skge->tx_ring.to_clean) in skge_up() was sometimes observed when setting MTU. skge_down() disables the TX queue, but then reenables it by mistake via skge_tx_clean(). Fix it by moving the waking of the queue from skge_tx_clean() to the other caller. And to make sure start_xmit is not in progress on another CPU, skge_down() should call netif_tx_disable(). The bug was reported to me by Jiri Jilek whose Debian system sometimes failed to boot. He tested the patch and the bug did not happen anymore.

| | | | | | | | | | | | | | | | | | | | According to: Documentation/networking/netdevices.txt: <cite> napi->poll: .......... Context: softirq will be called with interrupts disabled by netconsole. </cite> napi->poll() could be called either with interrupts enabled (in softirq context) or disabled (by netconsole), so the irq flag should be preserved.

* skge: MTU changing fixStephen Hemminger2007-12-011-33/+2Star
| | | | | | | | | | The code to change MTU doesn't correctly handle all the chip variations and requirements for restarting. On Genesis chips changing MTU would just cause receiver to hang. Use a simpler approach of just taking link down/up if needed. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>

* skge: fiber link up/down fixStephen Hemminger2007-12-011-7/+12
| | | | | | | | | | | The driver would not work over fibre if other end when down then came back up (would require reloading driver). The correct way to manage the link the same way for both TP and fibre.

* skge: FIFO Ram calculation errorStephen Hemminger2007-12-011-2/+2
| | | | | | | | | | The calculation of usable FIFO RAM is wrong in the skge driver. First, is doesn't take into account the reserved area on the original SysKonnect Genesis boards. Second it has an off-by-one error because hw->ports is either 1 or 2. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* Revert "skge: fix ram buffer size calculation"Linus Torvalds2007-11-151-24/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 7fb7ac241162dc51ec0f7644d4a97b2855213c32. Heikki Orsila reports that it causes a regression: "Doing nc host port < /dev/zero on a sending machine (not skge) to an skge machine that is receiving: nc -l -p port >/dev/null with ~60 MiB/s speed, causes the interface go malfunct. A slow transfer doesn't cause a problem." See http://bugzilla.kernel.org/show_bug.cgi?id=9321 for some more information. There is a workaround (also reported by Heikki): "After some fiddling, I noticed that not changing the register write order on patch: + skge_write32(hw, RB_ADDR(q, RB_END), end); skge_write32(hw, RB_ADDR(q, RB_WP), start); skge_write32(hw, RB_ADDR(q, RB_RP), start); - skge_write32(hw, RB_ADDR(q, RB_END), end); fixes the visible effect.. Possibly not the root cause of the problem, but changing the order back fixes networking here." but that has yet to be ack'ed or tested more widely, so the whole problem-causing commit gets reverted until this is resolved properly.
