2008-10-13sky2: Fix WOL regressionRafael J. Wysocki1-14/+5
Since dev->power.should_wakeup bit is used by the PCI core to decide whether the device should wake up the system from sleep states, set/unset this bit whenever WOL is enabled/disabled using sky2_set_wol(). Remove an open-coded reference to the standard PCI PM registers that is not used any more. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-09-03sky2: EEPROM read/write bug fixesStephen Hemminger1-42/+55
Cleanup and harden the routines accessing the EEPROM. 1. Prevent spin forever waiting for the TWSI bus 2. Fix write eeprom to write full words rather than only 16 bits Luckly the vendor doesn't provide EEPROM in Linux format so it must never have been used. 3. Don't allow partial eeprom writes, not needed, not safe. These are non-urgent bug fixes. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-08-14sky2: Fix suspend/hibernation/shutdown regression with WOL enabled (rev. 2)Rafael J. Wysocki1-1/+6
On my test box with the Asus M3A32-MVP main board there is a regression from 2.6.26 related to suspend, hibernation and shutdown. Namely, if Wake-on-LAN is enabled with 'ethtool -s eth0 wol g', the box hangs solid during all of these operations, while executing either sky2_suspend(), or sky2_shutdown(). This patch fixes it for me. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-01-29sky2: rx allocation threshold changeStephen Hemminger1-19/+9
When using larger MTU's sky2 driver changes from allocating one data area, to using multiple pages. The threshold for this was based on a heuristic where the cost of a single allocation is bigger than one page. Since the allocator has changed, this heuristic is now incorrect; instead just make the threshold be when the total size of the allocation is greater than one page.

This reverts commit 84cd2dfb04d23a961c5f537baa243fa54d0987ac. Some BIOS's break if Wake On Lan is enabled, and the machine can't boot.

2008-01-13sky2: remove check for PCI wakeup setting from BIOSStephen Hemminger1-19/+5
The driver checks status of PCI power management to mark default setting of Wake On Lan. On some systems this works, but often it reports a that WOL is disabled when it isn't.

2008-01-09[NET]: Fix drivers to handle napi_disable() disabling interrupts.David S. Miller1-0/+3
When we add the generic napi_disable_pending() breakout logic to net_rx_action() it means that napi_disable() can cause NAPI poll interrupt events to be disabled. And this is exactly what we want. If a napi_disable() is pending, and we are looping in the ->poll(), we want ->poll() event interrupts to stay disabled and we want to complete the NAPI poll ASAP. When ->poll() break out during device down was being handled on a per-driver basis, often these drivers would turn interrupts back on when '!netif_running()' was detected. And this would just cause a reschedule of the NAPI ->poll() in the interrupt handler before the napi_disable() could get in there and grab the NAPI_STATE_SCHED bit. The vast majority of drivers don't care if napi_disable() might have the side effect of disabling NAPI ->poll() event interrupts. In all such cases, when a napi_disable() is performed, the driver just disabled interrupts or is about to. However there were three exceptions to this in PCNET32, R8169, and SKY2. To fix those cases, at the subsequent napi_enable() points, I added code to ensure that the ->poll() interrupt events are enabled in the hardware. Signed-off-by: David S. Miller <davem@davemloft.net> Acked-by: Don Fry <pcnet32@verizon.net>
2007-12-14sky2: RX lockup fixStephen Hemminger1-2/+7
I'm using a Marvell 88E8062 on a custom PPC64 blade and ran into RX lockups while validating the sky2 driver. The receive MAC FIFO would become stuck during testing with high traffic. One port of the 88E8062 would lockup, while the other port remained functional. Re-inserting the sky2 module would not fix the problem - only a power cycle would. I looked over Marvell's most recent sk98lin driver and it looks like they had a "workaround" for the Yukon XL that the sky2 doesn't have yet. The sk98lin driver disables the RX MAC FIFO flush feature for all revisions of the Yukon XL. According to skgeinit.c of the sk98lin driver, "Flushing must be enabled (needed for ASF see dev. #4.29), but the flushing mask should be disabled (see dev. #4.115)". Nice. I implemented this same change in the sky2 driver and verified that the RX lockup I was seeing was resolved.

2007-12-04sky2: recovery deadlock fixStephen Hemminger1-4/+2
Prevent deadlock in sky2 recovery logic. sky2_down calls napi_synchronize which gets stuck if napi was already disabled. Fix by rearranging slightly and not calling napi_disable until after both ports are stopped. The napi_disable probably is being overly paranoid, but it is safe now.
