* cxgb4: Fix MC1 memory offset calculationHariprasad Shenai2015-04-29
| | | | | | | | | | | | Commit 6559a7e8296002b4 ("cxgb4: Cleanup macros so they follow the same style and look consistent") introduced a regression where reading MC1 memory in adapters where MC0 isn't present or MC0 size is not equal to MC1 size caused the adapter to crash due to incorrect computation of memoffset. Fix is to read the size of MC0 instead of MC1 for offset calculation Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Hariprasad Shenai <hariprasad@chelsio.com> Signed-off-by: David S.

* | cxgb4: drop __GFP_NOFAIL allocationMichal Hocko2015-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | set_filter_wr is requesting __GFP_NOFAIL allocation although it can return ENOMEM without any problems obviously (t4_l2t_set_switching does that already). So the non-failing requirement is too strong without any obvious reason. Drop __GFP_NOFAIL and reorganize the code to have the failure paths easier. The same applies to _c4iw_write_mem_dma_aligned which uses __GFP_NOFAIL and then checks the return value and returns -ENOMEM on failure. This doesn't make any sense what so ever. Either the allocation cannot fail or it can. del_filter_wr seems to be safe as well because the filter entry is not marked as pending and the return value is propagated up the stack up to c4iw_destroy_listen.

| * cxgb4: Fix to dump devlog, even if FW is crashedHariprasad Shenai2015-04-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new Common Code routines to retrieve Firmware Device Log parameters from PCIE_FW_PF[7]. The firmware initializes its Device Log very early on and stores the parameters for its location/size in that register. Using the parameters from the register allows us to access the Firmware Device Log even when the firmware crashes very early on or we're not attached to the firmware Based on original work by Casey Leedom <leedom@chelsio.com> Signed-off-by: Hariprasad Shenai <hariprasad@chelsio.com> Signed-off-by: David S.

| * cxgb4: Allocate dynamic mem. for egress and ingress queue mapsHariprasad Shenai2015-03-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | QIDs (egress/ingress) from firmware in FW_*_CMD.alloc command can be anywhere in the range from EQ(IQFLINT)_START to EQ(IQFLINT)_END. For eg, in the first load eqid can be from 100 to 300. In the next load it can be from 301 to 500 (assume eq_start is 100 and eq_end is 1000). The driver was assuming them to always start from EQ(IQFLINT)_START till MAX_EGRQ(INGQ). This was causing stack overflow and subsequent crash. Fixed it by dynamically allocating memory (of qsize (x_END - x_START + 1)) for these structures.

The conflict hunks generated by GIT were very unhelpful, to say the least. It split functions in half and moved them around, when the real actual conflict only existed solely inside of one function, that being be_map_pci_bars(). So instead, to resolve this, I checked out be_main.c from the top of net-next, then I applied the be_main.c changes from 'net' since the last time I merged. And this worked beautifully. The inet_diag.c and sysctl_net_core.c conflicts were simple overlapping changes, and were easily to resolve. Signed-off-by: David S. Miller <davem@davemloft.net>

* | cxgb4: Delete an unnecessary check before the function call "release_firmware"Markus Elfring2015-02-05
| | | | | | | | | | | | | | | | | | | | The release_firmware() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: David S. Miller <davem@davemloft.net>
* | cxgb4: Add low latency socket busy_poll supportHariprasad Shenai2015-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cxgb_busy_poll, corresponding to ndo_busy_poll, gets called by the socket waiting for data. With busy_poll enabled, improvement is seen in latency numbers as observed by collecting netperf TCP_RR numbers. Below are latency number, with and without busy-poll, in a switched environment for a particular msg size: netperf command: netperf -4 -H <ip> -l 30 -t TCP_RR -- -r1,1 Latency without busy-poll: ~16.25 us Latency with busy-poll : ~08.79 us Based on original work by Kumar Sanghvi <kumaras@chelsio.com> Signed-off-by: Hariprasad Shenai <hariprasad@chelsio.com> Signed-off-by: David S.

* | cxgb4: Remove preprocessor check for CONFIG_CXGB4_DCBHariprasad Shenai2015-02-02
| | | | | | | | | | | | | | | | | | | | | | | | | | In commit dc9daab226aa ("cxgb4: Added support in debugfs to dump sge_qinfo") a preprocessor check for CONFIG_CXGB4_DCB got added, which should have been CONFIG_CHELSIO_T4_DCB. After adding the right preprocessor, build fails due to missing function ethqset2pinfo. Fixing that as well.
