2011-10-24target: remove transport_generic_removeChristoph Hellwig1-29/+15
All callers that never have the session_reinstatement flag set can trivially be converted to transport_put_cmd. Opencode the session reinstatement code in transport_generic_free_cmd, which was the only caller ever asking for it.

2011-10-24target: simplify transport_put_cmdChristoph Hellwig1-41/+20
Inline two simple functions only used by it, and replace a goto with a simple if else construct. Note that the code moved from transport_dec_and_check seems fairly buggy - the atomic_read check on a variable where we'd do an atomic_dec_and_test looks racy if we'll ever get someone increment it without the lock held around them (which it looks like we do), and not decrementing the second counter if the first one doesn't hit zero also at least needs an explanation.

2011-10-24target: simplify transport_generic_removeChristoph Hellwig1-19/+14
Instead of duplicating the code from transport_release_fe_cmd re-use it by allowing transport_release_fe_cmd to return wether it actually freed the command or not. Also rename transport_release_fe_cmd to transport_put_cmd and add a kerneldoc comment for it to make the use case more obvious.

2011-10-24target: Prevent transport_send_task_abort when CHECK_CONDITION statusNicholas Bellinger1-0/+9
This patch fixes a bug where transport_send_task_abort() could be called during LUN_RESET to return SAM_STAT_TASK_ABORTED + tfo->queue_status(), when SCF_SENT_CHECK_CONDITION -> tfo->queue_status() has already been sent from within another context via transport_send_check_condition_and_sense().

2011-10-24target: Fix transport_cmd_finish_abort queue removal bugNicholas Bellinger1-2/+3
This patch fixes a bug in LUN_RESET operation with transport_cmd_finish_abort() where transport_remove_cmd_from_queue() was incorrectly being called, causing descriptors with t_state == TRANSPORT_FREE_CMD_INTR to be incorrectly removed from qobj->qobj_list during process context release. This change ensures the descriptor is only removed via transport_remove_cmd_from_queue() when doing a direct release via transport_generic_remove().

2011-10-24target: Prevent TRANSPORT_FREE_CMD_INTR processing in core_tmr_drain_cmd_listNicholas Bellinger1-0/+10
This patch contains a bugfix for TMR LUN_RESET related to TRANSPORT_FREE_CMD_INTR operation, where core_tmr_drain_cmd_list() will now skip processing for this case to prevent an ABORT_TASK status from being returned for descriptors that are already queued up to be released by processing thread context.

2011-10-24target: Re-org of core_tmr_lun_resetNicholas Bellinger1-72/+125
This patch is a re-orginzation of core_tmr_lun_reset() logic to properly scan the active tmr_list, dev->state_task_list and qobj->qobj_list w/ the relivent locks held, and performing a list_move_tail onto seperate local scope lists before performing the full drain. This involves breaking out the code into three seperate list specific functions: core_tmr_drain_tmr_list(), core_tmr_drain_task_list() and core_tmr_drain_cmd_list().

2011-10-24target: Prevent cmd->se_queue_node double addRoland Dreier2-17/+16
This patch addresses a bug with the lio-core-2.6.git conversion of transport_add_cmd_to_queue() to use a single embedded list_head, instead of individual struct se_queue_req allocations allowing a single se_cmd to be added to the queue mulitple times. This was changed in the following: commit 2a9e4d5ca5d99f4c600578d6285d45142e7e5208 Author: Andy Grover <agrover@redhat.com> Date: Tue Apr 26 17:45:51 2011 -0700 target: Embed qr in struct se_cmd The problem is that some target code still assumes performing multiple adds is allowed via transport_add_cmd_to_queue(), which ends up causing list corruption in qobj->qobj_list code. This patch addresses this by removing an existing struct se_cmd from the list before the add, and removes an unnecessary list walk in transport_remove_cmd_from_queue() It also changes cmd->t_transport_queue_active to use explict sets intead of increment/decrement to prevent confusion during exception path handling.

2011-10-10MAINTAINERS: Update tegra maintainer informationOlof Johansson1-2/+2
A couple of changes to the Tegra maintainership setup: I'm very glad to bring on Stephen Warren on board as a maintainer. The work he has done so far is excellent, and the fact that he works for Nvidia means he has long-term interest in the platform. Erik Gilling did an astounding amount of work on getting things up and running but has been a silent partner on the maintainership side for a while, and is stepping down. Thanks for your contributions so far, Erik. Finally, update the git URL since I'll take over running the main repo for a while. Overall maintainership model isn't changing much at this time: We'll all three review patches as appropriate, and one of us will collect the main repo (me at this time).

2011-10-06x86/PCI: use host bridge _CRS info on ASUS M2V-MX SEPaul Menzel1-0/+11
In summary, this DMI quirk uses the _CRS info by default for the ASUS M2V-MX SE by turning on `pci=use_crs` and is similar to the quirk added by commit 2491762cfb47 ("x86/PCI: use host bridge _CRS info on ASRock ALiveSATA2-GLAN") whose commit message should be read for further information.

2011-10-04tcp: properly update lost_cnt_hint during shiftingYan, Zheng1-3/+1
lost_skb_hint is used by tcp_mark_head_lost() to mark the first unhandled skb. lost_cnt_hint is the number of packets or sacked packets before the lost_skb_hint; When shifting a skb that is before the lost_skb_hint, if tcp_is_fack() is ture, the skb has already been counted in the lost_cnt_hint; if tcp_is_fack() is false, tcp_sacktag_one() will increase the lost_cnt_hint. So tcp_shifted_skb() does not need to adjust the lost_cnt_hint by itself. When shifting a skb that is equal to lost_skb_hint, the shifted packets will not be counted by tcp_mark_head_lost(). So tcp_shifted_skb() should adjust the lost_cnt_hint even tcp_is_fack(tp) is true. Signed-off-by: Zheng Yan <zheng.z.yan@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Packets should always be forwarded to the lowerdev using dev_forward_skb. vlan->forward is for packets being forwarded directly to another macvlan/ macvtap device (used for multicast in bridge mode).

2011-10-04PCI: Disable MPS configuration by defaultJon Mason3-3/+20
Add the ability to disable PCI-E MPS turning and using the BIOS configured MPS defaults. Due to the number of issues recently discovered on some x86 chipsets, make this the default behavior. Also, add the option for peer to peer DMA MPS configuration. Peer to peer DMA is outside the scope of this patch, but MPS configuration could prevent it from working by having the MPS on one root port different than the MPS on another. To work around this, simply make the system wide MPS the smallest possible value (128B).

2011-10-04drm/radeon/kms: fix channel_remap setup (v2)Alex Deucher3-127/+0
Most asics just use the hw default value which requires no explicit programming. For those that need a different value, the vbios will program it properly. As such, there's no need to program these registers explicitly in the driver. Changing MC_SHARED_CHREMAP requires a reload of all data in vram otherwise its contents will be scambled. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=40103 v2: drop now unused channel_remap functions.

2011-10-04spi-topcliff-pch: Fix overrun issueTomoya MORINAGA1-5/+23
We found that adding load, Rx data sometimes drops.(with DMA transfer mode) The cause is that before starting Rx-DMA processing, Tx-DMA processing starts. This causes FIFO overrun occurs. This patch fixes the issue by modifying FIFO tx-threshold and DMA descriptor size like below. Current this patch Rx-descriptor 4Byte+12Byte*341 --> 12Byte*340-4Byte-12Byte Rx-threshold (Not modified) Tx-descriptor 4Byte+12Byte*341 --> 16Byte-12Byte*340 Rx-threshold 12Byte --> 2Byte Signed-off-by: Tomoya MORINAGA <tomoya-linux@dsn.okisemi.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
