2011-12-23dma: mxs-dma: Always leave mxs_dma_init() with the clock disabled.Lothar Waßmann1-5/+2
There is no need to have the clock enabled all the time the driver is loaded. It will be enabled anyway in mxs_dma_alloc_chan_resources() when a channel is actually going to be used. Signed-off-by: Lothar Waßmann <LW@KARO-electronics.de> Signed-off-by: Vinod Koul <vinod.koul@linux.intel.com>

2011-12-08DMA: PL330: Remove pm_runtime_xxx calls from pl330 probe/removeTushar Behera1-15/+2
amba_probe() now calls pm_runtime_get_noresume() and pm_runtime_enable() for the devices before the device probe is called. Hence we don't need to call pm_runtime_get_xxx and pm_runtime_enable() in device probe again. In the same way, since amba_remove() calls the respective pm_runtime functions, those functions need not be called from device remove.

2011-12-08video i.MX IPU: Fix display connectionsSascha Hauer2-39/+37
The IPU internally works on 32bit colors. It can arbitrarily map between pixel formats and internal representation and also between internal representation and the physical connection to the display. The driver used to change the mapping between internal representation and display connection depending on the user selected bpp which is wrong. Instead, the mapping is specified by the hardware, so an additional field in platform data is added to describe the connection between i.MX and the display. The default for this field is RGB666 which seems to be the only configuration which works without this patch, so I assumed that all in Kernel boards are connected this way. This patch has been tested on a RGB666 connected display and a RGB888 connected display in both 16bpp and 32bpp modes.

2011-12-08i.MX IPU DMA: Fix wrong burstsize settingsSascha Hauer1-24/+1
The burstsize (npb in struct chan_param_mem) is set in ipu_ch_param_set_size() once. The number of allowed pixels in a burst depend on the pixel format and the rotation mode. For 16bit formats 16 pixels are allowed whereas for 32bit formats only 8 pixels are allowed. Set these values correctly in ipu_ch_param_set_size() and do not overwrite them afterwards. We do not support rotation right now, so ignore this case. This patch fixes the wrong burstsize setting of 16 pixels for 32bpp. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Vinod Koul <vinod.koul@linux.intel.com>

2011-12-05IMX/SDMA : save the real count for one DMA transaction.Huang Shijie1-2/+9
When we use the SDMA in the UART driver(such as imx6q), we will meet one situation: Assume we set 64 bytes for the RX DMA buffer. The RX DMA buffer has received some data, but not full. An Aging DMA request will be received by the SDMA controller if we enable the IDDMAEN(UCR4[6]) in this case. So the UART driver needs to know the count of the real received bytes, and push them to upper layer. Add two new fields to sdmac, and update the `residue` in sdma_tx_status().

2011-11-28dmaengine/dw_dmac: Reconfigure interrupt and chan_cfg register on resumeViresh Kumar2-28/+42
In S2R all DMA registers are reset by hardware and thus they are required to be reprogrammed. The channels which aren't reprogrammed are channel configuration and interrupt enable registers, which are currently programmed at chan_alloc time. This patch creates another routine to initialize a channel. It will try to initialize channel on every dwc_dostart() call. If channel is already initialised then it simply returns, otherwise it configures registers. This routine will also initialize registers on wakeup from S2R, as we mark channels as uninitialized on suspend.

2011-11-18DMAEngine: Define interleaved transfer request apiJassi Brar3-5/+85
Define a new api that could be used for doing fancy data transfers like interleaved to contiguous copy and vice-versa. Traditional SG_list based transfers tend to be very inefficient in such cases as where the interleave and chunk are only a few bytes, which call for a very condensed api to convey pattern of the transfer. This api supports all 4 variants of scatter-gather and contiguous transfer. Of course, neither can this api help transfers that don't lend to DMA by nature, i.e, scattered tiny read/writes with no periodic pattern. Also since now we support SLAVE channels that might not provide device_prep_slave_sg callback but device_prep_interleaved_dma, remove the BUG_ON check.

2011-11-08VFS: we need to set LOOKUP_JUMPED on mountpoint crossingAl Viro1-1/+15
Mountpoint crossing is similar to following procfs symlinks - we do not get ->d_revalidate() called for dentry we have arrived at, with unpleasant consequences for NFS4. Simple way to reproduce the problem in mainline: cat >/tmp/a.c <<'EOF' #include <unistd.h> #include <fcntl.h> #include <stdio.h> main() { struct flock fl = {.l_type = F_RDLCK, .l_whence = SEEK_SET, .l_len = 1}; if (fcntl(0, F_SETLK, &fl)) perror("setlk"); } EOF cc /tmp/a.c -o /tmp/test then on nfs4: mount --bind file1 file2 /tmp/test < file1 # ok /tmp/test < file2 # spews "setlk: No locks available"... What happens is the missing call of ->d_revalidate() after mountpoint crossing and that's where NFS4 would issue OPEN request to server. The fix is simple - treat mountpoint crossing the same way we deal with following procfs-style symlinks. I.e. set LOOKUP_JUMPED...

2011-11-07forcedeth: Improve stats countersMandeep Baines1-0/+4
Rx byte count was off; instead use the hardware's count. Tx packet count was counting pre-TSO packets; instead count on-the-wire packets. Report hardware dropped frame count as rx_fifo_errors. - The count of transmitted packets reported by the forcedeth driver reports pre-TSO (TCP Segmentation Offload) packet counts and not the count of the number of packets sent on the wire. This change fixes the forcedeth driver to report the correct count. Fixed the code by copying the count stored in the NIC H/W to the value reported by the driver. - Count rx_drop_frame errors as rx_fifo_errors: We see a lot of rx_drop_frame errors if we disable the rx bottom-halves for too long. Normally, rx_fifo_errors would be counted in this case. The rx_drop_frame error count is private to forcedeth and is not reported by ifconfig or sysfs. The rx_fifo_errors count is currently unused in the forcedeth driver. It is reported by ifconfig as overruns. This change reports rx_drop_frame errors as rx_fifo_errors.

2011-11-07forcedeth: remove unneeded stats updatesdavid decotigny1-34/+1
Function ndo_get_stats() updates most of the stats from hardware registers, making the manual updates un-needed. This change removes these manual updates. Main exception is rx_missed_errors which needs manual update. Another exception is rx_packets, still updated manually in this commit to make sure this patch doesn't change behavior of driver. This will be addressed by a future patch. Signed-off-by: David Decotigny <david.decotigny@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-11-07forcedeth: Acknowledge only interrupts that are being processedMike Ditto1-5/+8
This is to avoid a race, accidentally acknowledging an interrupt that we didn't notice and won't immediately process. This is based solely on code inspection; it is not known if there was an actual bug here. Signed-off-by: David Decotigny <david.decotigny@google.com> Signed-off-by: David S.

2011-11-07forcedeth: fix race when unloading moduledavid decotigny1-1/+1
When forcedeth module is unloaded, there exists a path that can lead to mod_timer() after del_timer_sync(), causing an oops. This patch short-circuits this unneeded path, which originates in nv_get_ethtool_stats(). Tested: x86_64 16-way + 3 ethtool -S infinite loops + 100Mbps incoming traffic + rmmod/modprobe/ifconfig in a loop Initial-Author: Salman Qazi <sqazi@google.com> Discussion: http://patchwork.ozlabs.org/patch/123548/ Signed-off-by: David Decotigny <david.decotigny@google.com> Signed-off-by: David S.

2011-11-07arm: Add export.h to recently added files for EXPORT_SYMBOLPaul Gortmaker2-0/+2
These files didn't exist at the time of the module.h split, and so were not fixed by the commits on that baseline. Since they use the EXPORT_SYMBOL and/or THIS_MODULE macros, they will need the new export.h file included that provides them.
