2019-08-30net: sgi: ioc3-eth: use dma-direct for dma allocationsThomas Bogendoerfer1-33/+113

2019-08-30net: sgi: ioc3-eth: refactor rx buffer allocationThomas Bogendoerfer1-50/+45
Move common code for rx buffer setup into ioc3_alloc_skb and deal with allocation failures. Also clean up allocation size calculation. Signed-off-by: Thomas Bogendoerfer <tbogendoerfer@suse.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-08-30net: sgi: ioc3-eth: split ring cleaning/freeing and allocationThomas Bogendoerfer1-15/+13
Do tx ring cleaning and freeing of rx buffers, when chip is shutdown and allocate buffers before bringing chip up. Signed-off-by: Thomas Bogendoerfer <tbogendoerfer@suse.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-08-30net: sgi: ioc3-eth: introduce chip start functionThomas Bogendoerfer1-20/+29
ioc3_init did everything from reset to init rings to starting the chip. This change move out chip start into a new function as preparation for easier handling of receive buffer allocation failures.

2019-08-30net: sgi: ioc3-eth: separate tx and rx ring handlingThomas Bogendoerfer1-12/+8
After allocation of descriptor memory is now done once in probe handling of tx ring is completely done by ioc3_clean_tx_ring. So we remove the remaining tx ring actions out of ioc3_alloc_rings and ioc3_free_rings and rename it to ioc3_[alloc|free]_rx_bufs to better describe what they are doing.

2019-08-30net: sgi: ioc3-eth: get rid of ioc3_clean_rx_ring()Thomas Bogendoerfer1-21/+1
Move clearing of the descriptor valid bit into ioc3_alloc_rings. This makes ioc3_clean_rx_ring obsolete. Signed-off-by: Thomas Bogendoerfer <tbogendoerfer@suse.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-08-30net: sgi: ioc3-eth: allocate space for desc rings only onceThomas Bogendoerfer1-53/+52
Memory for descriptor rings are allocated/freed, when interface is brought up/down. Since the size of the rings is not changeable by hardware, we now allocate rings now during probe and free it, when device is removed.

2019-08-30net: sgi: ioc3-eth: use defines for constants dealing with desc ringsThomas Bogendoerfer1-18/+24
Descriptor ring sizes of the IOC3 are more or less fixed size. To make clearer where there is a relation to ring sizes use defines.

2019-08-30MIPS: SGI-IP27: restructure ioc3 register accessThomas Bogendoerfer1-233/+185
Break up the big ioc3 register struct into functional pieces to make use in sub-function drivers more straightforward. And while doing that get rid of all volatile access by using readX/writeX.

2019-02-14net: sgi: replace dev_kfree_skb_irq by dev_consume_skb_irq for drop profilesYang Wei1-1/+1
dev_consume_skb_irq() should be called when skb xmit done. It makes drop profiles(dropwatch, perf) more friendly. Signed-off-by: Yang Wei <yang.wei9@zte.com.cn> Signed-off-by: David S. Miller <davem@davemloft.net>

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t', which is a typedef for an enum type, so make sure the implementation in this driver has returns 'netdev_tx_t' value, and change the function return type to netdev_tx_t.

2017-07-15ioc3-eth: store pointer to net_device for priviate areaJason A. Donenfeld1-9/+5
Computing the alignment manually for going from priv to pub is probably not such a good idea, and in general the assumption that going from priv to pub is possible trivially could change, so rather than relying on that, we change things to just store a pointer to pub.

2017-02-22lib/show_mem.c: teach show_mem to work with the given nodemaskMichal Hocko1-1/+1
show_mem() allows to filter out node specific data which is irrelevant to the allocation request via SHOW_MEM_FILTER_NODES. The filtering is done in skip_free_areas_node which skips all nodes which are not in the mems_allowed of the current process. This works most of the time as expected because the nodemask shouldn't be outside of the allocating task but there are some exceptions. E.g. memory hotplug might want to request allocations from outside of the allowed nodes (see new_node_page). Get rid of this hardcoded behavior and push the allocation mask down the show_mem path and use it instead of cpuset_current_mems_allowed. NULL nodemask is interpreted as cpuset_current_mems_allowed.

2016-10-13net: deprecate eth_change_mtu, remove usageJarod Wilson1-1/+0
With centralized MTU checking, there's nothing productive done by eth_change_mtu that isn't already done in dev_set_mtu, so mark it as deprecated and remove all usage of it in the kernel. All callers have been audited for calls to alloc_etherdev* or ether_setup directly, which means they all have a valid dev->min_mtu and dev->max_mtu. Now eth_change_mtu prints out a netdev_warn about being deprecated, for the benefit of out-of-tree drivers that might be utilizing it. Of note, dvb_net.c actually had dev->mtu = 4096, while using eth_change_mtu, meaning that if you ever tried changing it's mtu, you couldn't set it above 1500 anymore. It's now getting dev->max_mtu also set to 4096 to remedy that. v2: fix up lantiq_etop, missed breakage due to drive not compiling on x86 CC: netdev@vger.kernel.org Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: David S.

A simplified version of the semantic patch that makes this change is as follows (http://coccinelle.lip6.fr/): // <smpl> @@ identifier i; declarer name DEFINE_PCI_DEVICE_TABLE; initializer z; @@ - DEFINE_PCI_DEVICE_TABLE(i) + const struct pci_device_id i[] = z; // </smpl> [bhelgaas: add semantic patch] Signed-off-by: Benoit Taine <benoit.taine@lip6.fr> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2014-01-16drivers/net: delete non-required instances of include <linux/init.h>Paul Gortmaker1-1/+0
None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

2012-06-06ethernet: Remove casts to same typeJoe Perches1-2/+2
Adding casts of objects to the same type is unnecessary and confusing for a human reader. For example, this cast: int y; int *p = (int *)&y; I used the coccinelle script below to find and remove these unnecessary casts. I manually removed the conversions this script produces of casts with __force, __iomem and __user. @@ type T; T *p; @@ - (T *)p + p A function in atl1e_main.c was passed a const pointer when it actually modified elements of the structure. Change the argument to a non-const pointer. A function in stmmac needed a __force to avoid a sparse warning. Added it. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S.
