| * bnx2x: Casting page alignmentEilon Greenstein2009-03-10
| | | | | | | | | | | | | | | | | | | | | | | | Adding a proper cast to the argument of PAGE_ALIGN macro so that the output won't depend on its original type. Without this cast aligned value will be truncated to the size of the argument type.

* bnx2x: Using system page size for SGEEilon Greenstein2009-01-15
| | | | | | | | | | | | When the page size is not 4KB, the FW must be programmed to work with the right SGE boundaries and fragment list length. To avoid confusion with the BCM_PAGE_SIZE which is set to 4KB for the FW sake, another alias for the system page size was added to explicitly indicate that it is meant for the SGE Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* bnx2x: Using singlethread work queueEilon Greenstein2009-01-15
| | | | | | | | | | | | | Since slow-path events, including link update, are handled in work-queue, a race condition was introduced in the self-test that sometimes caused the link status to fail: the self-test was running under RTNL lock, and if the link-watch was scheduled it stoped the shared work-queue (waiting for the RTNL lock) and so the link update event was not handled until the self-test ended (releasing the RTNL lock) with failure (since the link status was not updated) Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* bnx2x: Accessing un-mapped pageEilon Greenstein2008-09-03
| | | | | | | | | | | | | | | | The allocated RX buffer size was 64 bytes bigger than the PCI mapped size with no good reason. If the packet was actually using the buffer up to its limit and if the last 64 bytes of the buffer crossed 4KB boundary then an unmapped PCI page was accessed. The fix is to use only one parameter for the buffer size - there is no need to differentiate between the buffer size and the PCI mapping size since the extra 64 bytes can actually be used by the FW to align the Ethernet payload to 64 bytes. Also updating the driver version and date Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* bnx2x: Rx work checkEilon Greenstein2008-08-25
| | | | | | | | | | | | The has Rx work check was wrong: when the FW was at the end of the page, the driver was already at the beginning of the next page. Since the check only validated that both driver and FW are pointing to the same place, it concluded that there is still work to be done. This caused some serious issues including long latency results on ping-pong test and lockups while unloading the driver in that condition.

| | | | | | | | | | | | | | | | | | | | | | | Load/Unload under traffic Few issues were found when loading and unloading under traffic: - When receiving Tx interrupt call netif_wake_queue if the queue is stopped but the state is open - Check that interrupts are enabled before doing anything else on the msix_fp_int function - In nic_load, enable the interrupts only when needed and ready for it - Function stop_leading returns status since it can fail - Add 1ms delay when unloading the driver to validate that there are no open transactions that already started by the FW - Splitting the "has work" function into Tx and Rx so the same function will be used on unload and interrupts - Do not request for WoL if only resetting the device (save the time that it takes the FW to set the link after reset) - Fixing the device reset after iSCSI boot and before driver load - all internal buffers must be cleared before the driver is loaded Signed-off-by: Vladislav Zolotarov <vladz@broadcom.com> Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S.

* bnx2x: Add TPA, Broadcoms HW LROVladislav Zolotarov2008-06-23
| | | | | | | | | | | | | | | | | The TPA stands for Transparent Packet Aggregation. When enabled, the FW aggregate in-order TCP packets according to the 4-tuple match and sends 1 big packet to the driver. This packet is stored on an SGL in which each SGE is 1 page. The FW also implements a timeout algorithm and it honors all TCP flag, including the push flag as a trigger to halt aggregation. After receiving Ben Hutchings comments, we also added ethtool support, so now, thanks to Ben's patch, when forwarding is enabled, our aggregation is turned off using the LRO flags.

* bnx2x: Add support for BCM57711 HWEilon Greenstein2008-06-23
| | | | | | | | | | | | | | | Supporting the 57711 and 57711E - refers to in the code as E1H. The 57710 is referred to as E1. To support the new members in the family, the bnx2x structure was divided to 3 parts: common, port and function. These changes caused some rearrangement in the bnx2x.h file. A set of accessories macros were added to make access to the bnx2x structure more readable Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* bnx2x: New init infrastructureEilon Greenstein2008-06-23
| | | | | | | | | | | | | | | | | | | This new initialization code supports the 57711 HW. It also supports the emulation and FPGA for the 57711 and 57710 initializations values (very small amount of code which is very helpful in the lab - less than 30 lines). The initialization is done via DMAE after the DMAE block is ready - before it is ready, some of the initialization is done via PCI configuration transactions (referred to as indirect write). A mutex to protect the DMAE from being overlapped was added. There are few new registers which needs to be initialized by SW - the full comment for those registers is added to the register file. A place holder for the 57711 (referred to as E1H) microcode was added- the microcode itself is too big and it is split over the following 4 patches Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S.

* bnx2x: New link codeYaniv Rosner2008-06-23
| | | | | | | | | | | | | | | | | | | | | | | | New Link code: Moving all the link related code (including the calculations, the initialization of the MAC and PHY and the external PHY's code) into a separated file. The changes from the code that used to be part of bnx2x.c (now called bnx2x_main.c) are: - Using separate structures for link inputs and link outputs to clearly identify what was configured and what is the outcome - Adding code to read external PHY FW version and print it as part of ethtool -i - Adding code to upgrade external PHY FW from ethtool -E with special magic number - Changing the link down indication to ERR level - Adding a lock on all PHY access to prevent an interrupt and setting changes to overlap - Adding support for emulation and FPGA (small chunk of code that really helps in the lab) - Adding support for 1G on BCM8706 PHY - Adding clear debug print incase of fan failure (the PHY type is now "failure") Signed-off-by: Yaniv Rosner <yanivr@broadcom.com> Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S.

Use GPIO to clear all previous configurations before changing link parameters. Shut down the external PHY in case of fan failure. Reducing the MDC/MDIO clock to 2.5MHz due to problems with some devices. Resolve the flow control response according to autoneg with external PHY. Unmasking all PHY interrupts in single write to prevent a race in the interrupts order. LASI indication fixes to work with peculiarities of PHYs. Disable MAC RX to avoid a HW bug when closing the MAC under traffic. Disable parallel detection on HiGig due to HW limitation. Updating the shared memory structure to work with the current bootcode.
