| * [POWERPC] qe: miscellaneous code improvements and fixes to the QE libraryTimur Tabi2007-10-081-1/+1

Remove struct ucc_common and merge ucc_init_guemr() into ucc_set_type() (every caller of ucc_init_guemr() also calls ucc_set_type()). Modify all callers of ucc_set_type() accordingly. 2. Remove the unused enum ucc_pram_initial_offset. 3. Refactor qe_setbrg(), also implement work-around for errata QE_General4. 4. Several printk() calls were missing the terminating \n. 5. Add __iomem where needed, and change u16 to __be16 and u32 to __be32 where appropriate. 6. In ucc_slow_init() the RBASE and TBASE registers in the PRAM were programmed with the wrong value. 7. Add the protocol type to struct us_info and updated ucc_slow_init() to use it, instead of always programming QE_CR_PROTOCOL_UNSPECIFIED. 8. Rename ucc_slow_restart_x() to ucc_slow_restart_tx() 9. Add several macros in qe.h (mostly for slow UCC support, but also to standardize some naming convention) and remove several unused macros. 10. Update ucc_geth.c to use the new macros. 11. Add ucc_slow_info.protocol to specify which QE_CR_PROTOCOL_xxx protcol to use when initializing the UCC in ucc_slow_init(). 12. Rename ucc_slow_pram.rfcr to rbmr and ucc_slow_pram.tfcr to tbmr, since these are the real names of the registers. 13. Use the setbits, clrbits, and clrsetbits where appropriate. 14. Refactor ucc_set_qe_mux_rxtx(). 15. Remove all instances of 'volatile'. 16. Simplify get_cmxucr_reg(); 17. Replace qe_mux.cmxucrX with qe_mux.cmxucr[]. 18. Updated struct ucc_geth because struct ucc_fast is not padded any more. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* | [NET]: Make NAPI polling independent of struct net_device objects.Stephen Hemminger2007-10-101-31/+33
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [POWERPC] Change rheap functions to use ulongs instead of pointersTimur Tabi2007-05-091-15/+15
| | | | | | | | | | | | | | | | | | | | The rheap allocation functions return a pointer, but the actual value is based on how the heap was initialized, and so it can be anything, e.g. an offset into a buffer. A ulong is a better representation of the value returned by the allocation functions. This patch changes all of the relevant rheap functions to use a unsigned long integers instead of a pointer. In case of an error, the value returned is a negative error code that has been cast to an unsigned long. The caller can use the IS_ERR_VALUE() macro to check for this. All code which calls the rheap functions is updated accordingly. Macros IS_MURAM_ERR() and IS_DPERR(), have been deleted in favor of IS_ERR_VALUE(). Also added error checking to rh_attach_region().

The current code doesn't check if p_tx_bd_ring[i] is null, generating a kernel panic when trying to free the associated socket buffers. The function can also fail when accessing the uninitialized list_head structures ugeth->group_hash_q and ugeth->ind_hash_q. In the current implementation the list heads are initialized only when maxGroupAddrInHash and maxIndAddrInHash are positive values, although I think it's better to always initialize them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | migrate ucc_geth to use the common phylib code.

Note that 'interface' property is still honoured if max-speed or interface-type are not present (backward compatible). o compile-time CONFIG_UGETH_HAS_GIGA is eliminated in favour of probe time speed derivation logic. o adjust_link streamlined to only operate on maccfg2 and upsmr.r10m, instead of reapplying static initial values related to the interface-type. o Addition of UEC MDIO of_platform driver requires platform code add 'mdio' type to id list prior to calling of_platform_bus_probe (separate patch). o ucc_struct_init introduced to reduce ucc_geth_startup complexity.

* Revert "ucc_geth: returns NETDEV_TX_BUSY when BD ring is full"Li Yang2007-03-231-2/+1
| | | | | | | | | | | | | | This reverts commit 18babd38547a042a4bfd4154a014d1ad33373eb0. Michael Barkowski points out that it's wrong, and I agree. The patch causes a problem rather than fixes one after another patch "ucc_geth: Fix BD processing" was applied. Before that patch, current packet should be blocked. However after the patch current packet is ok and we only need to block next.

* Update ucc_geth.c for new workqueue structureTimur Tabi2007-01-181-5/+7
| | | | | | | | | | | | | | The workqueue interface changed with David Howell's patch on 11/22/2006 (SHA 65f27f38446e1976cc98fd3004b110fedcddd189). Several drivers were updated with that patch to handle the new interface, but ucc_geth.c was not one of them. This patch updates ucc_geth.c to support the new model. A compiler warning in set_mac_addr() was also fixed. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
