2011-01-10Blackfin: bf533: merge fio_flag back into normal mach headersMike Frysinger2-55/+41
We don't want the BF533 to be different in terms of its MMR headers, so merge the FIO_FLAG helpers back into the normal place. To avoid circular dependencies with headers, turn the inline C funcs into CPP defines. Not like there will be any code size differences. Signed-off-by: Mike Frysinger <[email protected]>
2011-01-10Blackfin: bf561-ezkit: add SMP defconfigMike Frysinger1-0/+113

Use the same naming convention for DMA traffic MMRs (most were legacy anyways) so we can avoid useless ifdef trees. Same goes for MDMA names -- this actually allows us to undo a bunch of ifdef redirects that existed for this purpose alone. Signed-off-by: Mike Frysinger <[email protected]>

2011-01-10Blackfin: bfin_serial.h: unify heavily duplicated serial codeMike Frysinger29-1024/+377
Each Blackfin port has been duplicating UART structures and defines when there really is no need for it. So start a new bfin_serial.h header to unify all these pieces and give ourselves a fresh start. Signed-off-by: Mike Frysinger <[email protected]>
2011-01-10net/irda: bfin_sir: pull in serial headers for definesMike Frysinger1-0/+5
We're in the process of cleaning up the global Blackfin namespace, so the bfin_sir driver needs to pull in the serial header explicitly now. This does add a little transitional cruft to keep things compiling, but a follow up patch in this series will cull that. Signed-off-by: Mike Frysinger <[email protected]>

2011-01-10x86, lapic-timer: Increase the max_delta to 31 bitsPierre Tardy1-1/+1
Latest atom socs(penwell) does not have hpet timer. As their local APIC timer is clocked at 400KHZ, and the current code limit their Initial Counter register to 23 bits, they cannot sleep more than 1.34 seconds which leads to ~2 spurious wakeup per second (1 per thread) These SOCs support 32bit timer so we change the max_delta to at least 31bits. So we can at least sleep for 300 seconds. We could not find any previous chip errata where lapic would only have 23 bit precision As powertop is suggesting to activate HPET to "sleep longer", this could mean this problem is already known. Problem is here since very first implementation of lapic timer as a clock event e9e2cdb [PATCH] clockevents: i386 drivers.

2011-01-09ixgbe: update ntuple filter configurationAlexander Duyck5-371/+250
This change fixes several issues found in ntuple filtering while I was doing the ATR refactor. Specifically I updated the masks to work correctly with the latest version of ethtool, I cleaned up the exception handling and added detailed error output when a filter is rejected, and corrected several bits that were set incorrectly in ixgbe_type.h. The previous version of this patch included a printk that was left over from me fixing the filter setup. This patch does not include that printk.

2011-01-09ixgbe: further flow director performance optimizationsAlexander Duyck4-44/+194
This change adds a compressed input type for atr signature hash computation. It also drops the use of the set functions when setting up the ATR input since we can then directly setup the hash input as two dwords that can be stored and passed as registers. With these changes the cost of computing the has is low enough that we can perform a hash computation on each TCP SYN flagged packet allowing us to drop the number of flow director misses considerably in tests such as netperf TCP_CRR.

This change cleans up the layout of the flow director data, and the algorithm used to calculate the hash resulting in a 35x / 3500% performance increase versus the old flow director hash computation. The overall effect is only a 1% increase in transactions per second though due to the fact that only 1 packet in 20 are actually hashed upon. TCP_RR before: Socket Size Request Resp. Elapsed Trans.

2011-01-09ixgbe: make sure per Rx queue is disabled before unmapping the receive bufferYi Zou3-7/+39
When disable the Rx logic globally, we would also want to disable the per Rx queue receive logic by per queue Rx control register RXDCTL so no more DMA is happening from the packet buffer to the receive buffer associated with the Rx ring, before we start unmapping Rx ring receive buffer. The hardware may take max of 100us before the corresponding Rx queue is really disabled. Added ixgbe_disable_rx_queue() for this purpose.

2011-01-09e1000e: power off PHY after reset when interface is downBruce Allan3-35/+53
Some Phys supported by the driver do not remain powered off across a reset of the device when the interface is down, e.g. on 82571, but not on 82574. This patch powers down (only when WoL is disabled) the PHY after a reset if the interface is down and the ethtool diagnostics are not currently running. The ethtool diagnostic function required a minor re-factor as a result, and the e1000_[get|put]_hw_control() functions are renamed since they are no longer static to netdev.c as they are needed by the ethtool diagnostics. A couple minor whitespace issues were cleaned up, too.

2011-01-09net offloading: Convert checksums to use centrally computed features.Jesse Gross1-28/+12
In order to compute the features for other offloads (primarily scatter/gather), we need to first check the ability of the NIC to offload the checksum for the packet. Since we have already computed this, we can directly use the result instead of figuring it out again. Signed-off-by: Jesse Gross <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2011-01-09net offloading: Convert skb_need_linearize() to use precomputed features.Jesse Gross1-15/+6
This switches skb_need_linearize() to use the features that have been centrally computed. In doing so, this fixes a problem where scatter/gather should not be used because the card does not support checksum offloading on that type of packet. On device registration we only check that some form of checksum offloading is available if scatter/gatther is enabled but we must also check at transmission time. Examples of this include IPv6 or vlan packets on a NIC that only supports IPv4 offloading. Signed-off-by: Jesse Gross <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2011-01-09net offloading: Convert dev_gso_segment() to use precomputed features.Jesse Gross1-5/+3
This switches dev_gso_segment() to use the device features computed by the centralized routine. In doing so, it fixes a problem where it would always use dev->features, instead of those appropriate to the number of vlan tags if any are present.

2011-01-09net offloading: Pass features into netif_needs_gso().Jesse Gross3-12/+10
Now that there is a single function that can compute the device features relevant to a packet, we don't want to run it for each offload. This converts netif_needs_gso() to take the features of the device, rather than computing them itself. Signed-off-by: Jesse Gross <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2011-01-09net offloading: Generalize netif_get_vlan_features().Jesse Gross2-10/+29
netif_get_vlan_features() is currently only used by netif_needs_gso(), so it only concerns itself with GSO features. However, several other places also should take into account the contents of the packet when deciding whether to offload to hardware. This generalizes the function to return features about all of the various forms of offloading. Since offloads tend to be linked together, this avoids duplicating the logic in each location (i.e. the scatter/gather code also needs the checksum logic).

2011-01-09net offloading: Accept NETIF_F_HW_CSUM for all protocols.Jesse Gross1-1/+1
We currently only have software fallback for one type of checksum: the TCP/UDP one's complement. This means that a protocol that uses hardware offloading for a different type of checksum (FCoE, SCTP) must directly check the device's features and do the right thing ahead of time. By the time we get to dev_can_checksum(), we're only deciding whether to apply the one algorithm in software or hardware. NETIF_F_HW_CSUM has the same capabilities as the software version, so we should always use it if present. The primary advantage of this is multiply tagged vlans can use hardware checksumming.

2011-01-10nilfs2: unfold nilfs_dat_inode functionRyusuke Konishi7-30/+19
nilfs_dat_inode function was a wrapper to switch between normal dat inode and gcdat, a clone of the dat inode for garbage collection.

2011-01-10nilfs2: fiemap supportRyusuke Konishi6-0/+222
This adds fiemap to nilfs. Two new functions, nilfs_fiemap and nilfs_find_uncommitted_extent are added. nilfs_fiemap() implements the fiemap inode operation, and nilfs_find_uncommitted_extent() helps to get a range of data blocks whose physical location has not been determined. nilfs_fiemap() collects extent information by looping through nilfs_bmap_lookup_contig and nilfs_find_uncommitted_extent routines.

2011-01-10nilfs2: mark buffer heads as delayed until the data is written to diskRyusuke Konishi2-0/+3
Nilfs does not allocate new blocks on disk until they are actually written to. To implement fiemap, we need to deal with such blocks. To allow successive fiemap patch to distinguish mapped but unallocated regions, this marks buffer heads of those new blocks as delayed and clears the flag after the blocks are written to disk.

2011-01-10drm/radeon/kms: disable underscan by defaultAlex Deucher1-3/+3
Lots of HDMI TVs overscan the incoming image by default. The underscan option was added as a way to compensate for that by underscanning the image so that the edges would not be cut off on an overscanning TV. However, the TV provides no way of knowing whether it is overscanning or not. If the user has disabled overscan on their TV or has a TV that does not overscan, you will get black bars around the edges of your screen. Prior to the patch we got complaints and bug reports from users with overscanning TVs, now with the patch, we get lots of complaints and bug reports from users with non-overscanning TVs. There's no good default, but on average there have been more users complaining about it being on by default than off, so change it to off. This will probably result in a new deluge of overscanning TV user complaints. There's no winning. Signed-off-by: Alex Deucher <[email protected]> Signed-off-by: Dave Airlie <[email protected]>
