* [TG3]: Convert to non-LLTXMichael Chan2006-06-18
| | | | | | | | | | | | | | | | | | Herbert Xu pointed out that it is unsafe to call netif_tx_disable() from LLTX drivers because it uses dev->xmit_lock to synchronize whereas LLTX drivers use private locks. Convert tg3 to non-LLTX to fix this issue. tg3 is a lockless driver where hard_start_xmit and tx completion handling can run concurrently under normal conditions. A tx_lock is only needed to prevent netif_stop_queue and netif_wake_queue race condtions when the queue is full. So whether we use LLTX or non-LLTX, it makes practically no difference.

* [TG3]: Remove unnecessary tx_lockMichael Chan2006-06-18
| | | | | | | | | | Remove tx_lock where it is unnecessary. tg3 runs lockless and so it requires interrupts to be disabled and sync'ed, netif_queue and NAPI poll to be stopped before the device can be reconfigured. After stopping everything, it is no longer necessary to get the tx_lock. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* [TG3]: Add recovery logic when MMIOs are re-orderedMichael Chan2006-06-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add recovery logic when we suspect that the system is re-ordering MMIOs. Re-ordered MMIOs to the send mailbox can cause bogus tx completions and hit BUG_ON() in the tx completion path. tg3 already has logic to handle re-ordered MMIOs by flushing the MMIOs that must be strictly ordered (such as the send mailbox). Determining when to enable the flush is currently a manual process of adding known chipsets to a list. The new code replaces the BUG_ON() in the tx completion path with the call to tg3_tx_recover(). It will set the TG3_FLAG_MBOX_WRITE_REORDER flag and reset the chip later in the workqueue to recover and start flushing MMIOs to the mailbox. A message to report the problem will be printed. We will then decide whether or not to add the host bridge to the list of chipsets that do re-ordering. We may add some additional code later to print the host bridge's ID so that the user can report it more easily. The assumption that re-ordering can only happen on x86 systems is also removed.

* [TG3]: Handle Sun onboard tg3 chips more correctly.David S. Miller2006-06-09
| | | | | | | | | | | | | | | | | | | | | Get rid of all the SUN_570X logic and instead: 1) Make sure MEMARB_ENABLE is set when we probe the SRAM for config information. If that is off we will get timeouts. 2) Always try to sync with the firmware, if there is no firmware running do not treat it as an error and instead just report it the first time we notice this condition. 3) If there is no valid SRAM signature, assume the device is onboard by setting TG3_FLAG_EEPROM_WRITE_PROT. Update driver version and release date. With help from Michael Chan and Fabio Massimo Di Nitto. Signed-off-by: David S. Miller <davem@davemloft.net>

* [TG3]: Fix possible NULL deref in tg3_run_loopback().Jesper Juhl2006-05-10
| | | | | | | | | | | | tg3_run_loopback doesn't check that dev_alloc_skb() returns anything useful. Even if dev_alloc_skb() fails to return an skb to us we'll happily go on and assume it did, so we risk dereferencing a NULL pointer.

* [TG3]: Add reset_phy parameter to chip reset functionsGary Zambrano2006-04-29
| | | | | | | | | | | | Add a reset_phy parameter to tg3_reset_hw() and tg3_init_hw(). With the full chip reset during MAC address change, the automatic PHY reset during chip reset will cause a link down and bonding will not work properly as a result. With this reset_phy parameter, we can do a chip reset without link down when changing MAC address or MTU.

* [TG3]: Speed up SRAM access (2nd version)Michael Chan2006-04-10
| | | | | | | | | | | | | | | | | | | | | | | | Speed up SRAM read and write functions if possible by using MMIO instead of config. cycles. With this change, the post reset signature done at the end of D3 power change must now be moved before the D3 power change. IBM reported a problem on powerpc blades during ethtool self test that was caused by the memory test taking excessively long. Config. cycles are very slow on powerpc and the memory test can take more than 10 seconds to complete using config. cycles. David Miller informed me that an earlier version of the patch caused problems on sparc64 systems with built-in tg3 chips. This version fixes the problem by excluding all SUN built-in tg3 chips from doing MMIO SRAM access. TG3_FLAG_EEPROM_WRITE_PROT is also set unconditionally when TG3_FLG2_SUN_570X is set. This should be sane as all SUN chips are built-in and do not require Vaux switching. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | Move the netif_carrier_off() call from tg3_init_one()-> tg3_init_link_config() to tg3_open() as is the convention for most other network drivers. I was getting a panic after a tg3 device failed to initialize due to DMA failure. The oops pointed to the link watch queue with spinlock debugging enabled. Without spinlock debugging, the Oops didn't occur. I suspect that the link event was getting queued but not executed until after the DMA test had failed and the device was freed. The link event was then operating on freed memory, which could contain anything. With this patch applied, the Oops no longer occurs.
