* qla3xxx: Kernic Panic on pSeries under stress conditionsBenjamin Li2007-02-271-18/+46
| | | | | | | | | | | | | | | | | | | | To reproduce this panic consistently, we run an intensive network application like 'netperf'. After waiting for a couple of seconds, you will see a stack trace and a kernel panic where we are calling pci_unmap_single() in ql_poll(). Changes: 1) Check the flags on the Response MAC IO Control block to check for errors 2) Ensure that if we are on the 4022 we only use one segment 3) Before, we were reading the memory mapped producer index register everytime we iterated in the loop when clearing the queue. We should only be iterating to a known point, not as the producer index is being updated.

* qla3xxx: bugfix tx reset after stress conditions.Ron Mercer2007-02-271-28/+41
| | | | | | | | | | | | | | | | | To Reproduce the Problem: To reproduce this panic consistently, we run an intensive network application like 'netperf' and then switch to a different console. After waiting for a couple of seconds, you will see a tx reset has occured. Reason: We enable interrupts even if we were not running. Solution: Now we will enable interrupts only after we are ready to give up the poll routine. Signed-off-by: Ron Mercer <ron.mercer@qlogic.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* qla3xxx: Check return code from pci_map_single() in ↵Benjamin Li2007-02-271-7/+107
| | | | | | | | | | | | ql_release_to_lrg_buf_free_list(), ql_populate_free_queue(), ql_alloc_large_buffers(), and ql3xxx_send() pci_map_single() could fail. We need to properly check the return code from pci_map_single(). If we can not properly map this address, then we should cleanup and return the proper return code.

* qla3xxx: Dynamically size the rx buffer queue based on the MTU.Ron Mercer2007-02-271-13/+28
| | | | | | | | | This change removes use of constants for rx buffer queue size and instead calculates the queue length based on what he MTU is set to. Signed-off-by: Ron Mercer <ron.mercer@qlogic.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* qla3xxx: Remove API to change MTU.Ron Mercer2007-02-271-22/+2
| | | | | | | | | | | | | This network device driver shares the same hardware as the qla4xxx iSCSI driver. Changing the MTU via the device interface will cause qla4xxx to crash as there is no way to make notification. Users wishing to change the MTU must do so using an iSCSI utility such as Qlogic SanSurfer. This forces the user to unload/reload this network device driver after the MTU value has been changed in flash.

* qla3xxx: Remove unnecessary memset() in qla3xxx_send()Benjamin Li2007-02-271-1/+0
| | | | | | | | | | | | We do not need to zero out the 64 byte MAC request I/O control block. By zeroing out the control block and setting it to proper fields is redundant work. This is because in the qla3xxx_send() function we will already set the proper fields in this structure. The unused fields are not looked at by the hardware and do not need to be zeroed out.

* qla3xxx: Return proper error codes when the 4022/4032 is being probedBenjamin Li2007-02-271-1/+7
| | | | | | | | | | | | The return code was not properly set when when allocating memory or mapping memory failed. Depending on the stack, the return code would sometimes return 0, which indicates everything was ok, when in fact there was an error. This would cause trouble when the module was removed. Now, we will pass back the proper return code when an error occurs during the PCI probe.

* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

This is a complementary network driver for our ISP4XXX parts. There is a concurrent effort underway to get the iSCSI driver (qla4xxx) integrated upstream as well. I have been through several iterations with the linux-netdev list and have had much response from Stephen Hemminger. - Built and tested using kernel 2.6.17-rc4. - The chip supports two ethernet and two iSCSI functions. - The functions ql_sem_lock, ql_sem_spinlock, ql_sem_unlock, and ql_wait_for_drvr_lock are used to protect resources that are shared across the network and iSCSI functions. This protection is mostly during chip initialization and resets, but also include link management. - The PHY/MII are not exported through ethtool due to the fact that the iSCSI function will control the common link at least 50% of the time. This driver has been through several iterations on the netdev list and we feel this driver is ready for inclusion in the upstream kernel. It has been built and tested on x86 and PPC64 platforms.
