| * [TG3]: Fix performance regression on 5705.Michael Chan2007-10-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A performance regression was introduced by the following commit: commit ee6a99b539a50b4e9398938a0a6d37f8bf911550 Author: Michael Chan <mchan@broadcom.com> Date: Wed Jul 18 21:49:10 2007 -0700 [TG3]: Fix msi issue with kexec/kdump. In making that change, the PCI latency timer and cache line size registers were not restored after chip reset. On the 5705, the latency timer gets reset to 0 during chip reset and this causes very poor performance. Update version to 3.84.

* [TG3]: Refine napi poll loop.Michael Chan2007-10-12
| | | | | | | | | | | | | | Need to read and store sblk->status_tag before checking for more work. The status tag is later written back to the hardware when enabling interrupts to acknowledge how much work has been processed. If the order is reversed, we can end up acknowledging work we haven't processed. When we detect tx error, it is more correct to return the rx work_done so far instead of 0.

* [NET]: Fix NAPI completion handling in some drivers.David S. Miller2007-10-11
| | | | | | | | | | | | | | | | | | | | | In order for the list handling in net_rx_action() to be correct, drivers must follow certain rules as stated by this comment in net_rx_action(): /* Drivers must not modify the NAPI state if they * consume the entire weight. In such cases this code * still "owns" the NAPI instance and therefore can * move the instance around on the list at-will. */ A few drivers do not do this because they mix the budget checks with reading hardware state, resulting in crashes like the one reported by takano@axe-inc.co.jp.

Honor the advertisement bitmask from ethtool. We used to always advertise the full capability when autoneg was set to on. changed things around so that ethtool speed settings were strictly followed. Unfortunately ethtool doesn't seem to set ADVERTISED_Autoneg in the advertising field (and maybe it shouldn't have to). I'd vote that it should be fixed there, but it should also be added here just in case someone using ethtool ioctls in their own application gets what they want. Adding that flag in tg3_set_settings seemed like the most logical place since the driver works fine on boot. This is just an issue when re-enabling autonegotiation, so we should probably nip it there.

* [NET]: Make NAPI polling independent of struct net_device objects.Stephen Hemminger2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several devices have multiple independant RX queues per net device, and some have a single interrupt doorbell for several queues. In either case, it's easier to support layouts like that if the structure representing the poll is independant from the net device itself. The signature of the ->poll() call back goes from: int foo_poll(struct net_device *dev, int *budget) to int foo_poll(struct napi_struct *napi, int budget) The caller is returned the number of RX packets processed (or the number of "NAPI credits" consumed if you want to get abstract). The callee no longer messes around bumping dev->quota, *budget, etc. because that is all handled in the caller upon return. The napi_struct is to be embedded in the device driver private data structures. Furthermore, it is the driver's responsibility to disable all NAPI instances in it's ->stop() device close handler. Since the napi_struct is privatized into the driver's private data structures, only the driver knows how to get at all of the napi_struct instances it may have per-device.

* [TG3]: Workaround MSI bug on 5714/5780.Michael Chan2007-09-11
| | | | | | | | | | | | | | | | | | | | A hardware bug was revealed after a recent PCI MSI patch was made to always disable legacy INTX when enabling MSI. The 5714/5780 chips will not generate MSI when INTX is disabled, causing MSI failure messages to be reported, and another patch was made to workaround the problem by disabling MSI on ServerWorks HT1000 bridge chips commonly found with the 5714. We workaround this chip bug by enabling INTX after we enable MSI and after we resume from suspend. Update version to 3.81. This problem was discovered by David Miller.

| | | | | | | | | | | | | | Joachim Deguara <joachim.deguara@amd.com> reported that tg3 devices would not resume properly if the device was shutdown before the system was suspended. In such scenario where the netif_running state is 0, tg3_suspend() would not save the PCI state and so the memory enable bit and bus master enable bit would be lost. We fix this by always saving and restoring the PCI state in tg3_suspend() and tg3_resume() regardless of netif_running() state.

* [TG3]: Fix msi issue with kexec/kdump.Michael Chan2007-07-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tina Yang <tina.yang@oracle.com> discovered an MSI related problem when doing kdump. The problem is that the kexec kernel is booted without going through system reset, and as a result, MSI may already be enabled when tg3_init_one() is called. tg3_init_one() calls pci_save_state() which will save the stale MSI state. Later on in tg3_open(), we call pci_enable_msi() to reconfigure MSI on the chip before we reset the chip. After chip reset, we call pci_restore_state() which will put the stale MSI address/data back onto the chip. This is no longer a problem in the latest kernel because pci_restore_state() has been changed to restore MSI state from internal data structures which will guarantee restoring the proper MSI state. But I think we should still fix it. Our save and restore sequence can still cause very subtle problems down the road. The fix is to have our own functions save and restore precisely what we need. We also change it to save and restore state inside tg3_chip_reset() in a more straight forward way. Thanks to Tina for helping to test and debug the problem.

This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For most pre-5705 devices, multiple link interrupts were being generated for a single physical link change. The source of the interrupts was determined to be unnecessary toggling of the MAC link polarity bit. This patch changes the way the link polarity bit gets configured. Where possible, code that dynamically configures the bit in response to link changes has been replaced by code that configures the bit once during initialization time and then leaves the bit alone. For correctness, this patch also limits the use of the bit to those devices where it is defined, namely devices before the 5705. This patch also corrects the link polarity configurations for 5700 devices when paired against a bcm5411 phy.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Gagan Arneja <gaagaan@gmail.com> pointed out that tg3_reset_task() could potentially race with another thread calling tg3_full_lock() such as the ethtool_set_xxx() functions. This may trigger the BUG_ON() in tg3_irq_quiesce() or cause the irq_sync flag to be out- of-sync. I think the easiest way to fix this is to get the tp->lock first before setting the irq_sync flag. This is safe to do because the tp->lock is never grabbed by the irq handler. This change will guarantee that the irq_sync flag updates will be serialized. We also have to change one spot to call tg3_netif_start() (which clears the irq_sync flag) before releasing the tp->lock. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

* [TG3]: Fix link problem on Dell's onboard 5906.Michael Chan2007-06-03
| | | | | | | | | | | | | | | | | | | The bug is caused by code that always set (TG3_FLAG_USE_MI_INTERRUPT | TG3_FLAG_USE_LINKCHG_REG) on all Dell's onboard devices. With these 2 flags set, the link status is polled by tg3_timer() and will only work when the PHY is set up to interrupt the MAC on link changes. This breaks 5906 because the 5906 PHY does not support TG3_FLAG_USE_MI_INTERRUPT the same as other PHYs. For correctness, only Dell's onboard 5701 needs these 2 flags to be set. This change will fix the 5906 problem and will change other Dell devices except 5700 and 5701 to use the more efficient interrupt-driven link changes. Update version to 3.77.

As a result, the IRQ may remain asserted after the IRQ handler exits, causing spurious interrupts. Flush the interrupt mailbox in non-MSI handlers to de-assert the IRQ immediately. This seems to be the most straight forward approach after discussion with Jeff Garzik and David Miller. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

* [TG3]: Add TG3_FLAG_SUPPORT_MSI flag.Michael Chan2007-05-05
| | | | | | | | | | And fix up the code to always allow MSI on 5714 A2. Call tg3_find_peer() earlier because we need that information before we can determine whether we can set TG3_FLAG_SUPPORT_MSI or not.

| | | | | | | | | | | This patch removes the use of the TG3_FLAG_5701_REG_WRITE_BUG flag. It's logic is only used to set a function pointer and thus the logic can be collapsed and the flag removed.

* [TG3]: Remove reset during MAC address changes.Michael Chan2007-05-05
| | | | | | | | | | | | | | | | | | The reset was added a while back so that ASF could re-init whatever MAC address it wanted to use after the MAC address was changed. Instead of resetting, we can just keep MAC address 1 unchanged during MAC address changes if MAC address 1 is different from MAC address 0. This fixes 2 problems: 1. Bonding calls set_mac_address in contexts that cannot sleep. It no longer sleeps with the chip reset removed. 2. When ASF shares the same MAC address as the NIC, it needs to always do that even when the MAC address is changed. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

* [TG3]: Improve NVRAM sizing.Matt Carlson2007-05-05
| | | | | | | | | | | | | | This patch changes the NVRAM sizing procedure so that the driver can take advantage of devices with 1:1 NVRAM strapping configurations. This is useful in cases where the traditional NVRAM sizing method fails. In the event that the flash size cannot be determined, the largest known NVRAM size is used. The patch also removes support for 5755 NVRAM devices that are not supported by Broadcom and adds explicit sizing for this device.

* [TG3]: Fix TSO bugs.Matt Carlson2007-05-05
| | | | | | | | | | | | | | | 1. Remove the check for skb->len greater than MTU when doing TSO. When the destination has a smaller MSS than the source, a TSO packet may be smaller than the MTU and we still need to process it as a TSO packet. 2. On 5705A3 devices with TSO enabled, the DMA engine can hang due to a hardware bug. This patch avoids the hanging condition by reducing the DMA burst size.
