2009-02-18atmel_serial might lose modem status changeAtsushi Nemoto
I found a problem of handling of modem status of atmel_serial driver. With the commit 1ecc26 ("atmel_serial: split the interrupt handler"), handling of modem status signal was splitted into two parts. The atmel_tasklet_func() compares new status with irq_status_prev, but irq_status_prev is not correct if signal status was changed while the port is closed. Here is a sequence to cause problem: 1. Remote side sets CTS (and DSR). 2. Local side close the port. 3. Local side clears RTS and DTR. 4. Remote side clears CTS and DSR. 5. Local side reopen the port. hw_stopped becomes 1. 6. Local side sets RTS and DTR. 7. Remote side sets CTS and DSR. Then CTS change interrupt can be received, but since CTS bit in irq_status_prev and new status is same, uart_handle_cts_change() will not be called (so hw_stopped will not be cleared, i.e. cannot send any data). I suppose irq_status_prev should be initialized at somewhere in open sequence. Itai Levi pointed out that we need to initialize atmel_port->irq_status as well here. His analysis is as follows: > Regarding the second part of the patch (which resets irq_status_prev), > it turns out that both versions of the patch (mine and Atsushi's) > still leave enough room for faulty behavior when opening the port. > > This is because we are not resetting both irq_status_prev and > irq_status in atmel_startup() to CSR, which leads faulty behavior in > the following sequences: > > First case: > 1. closing the port while CTS line = 1 (TX not allowed) > 2. setting CTS line = 0 (TX allowed) > 3. opening the port > 4. transmitting one char > 5. Cannot transmit more chars, although CTS line is 0 > > Second case: > 1. closing the port while CTS line = 0 (TX allowed) > 2. setting CTS line = 1 (TX not allowed) > 3. opening the port > 4. receiving some chars > 5. Now we can transmit, although CTS line is 1 > > This reason for this is that the tasklet is scheduled as a result of > TX or RX interrupts (not a status change!), in steps 4 above. Inside > the tasklet, the atmel_port->irq_status (which holds the value from > the previous session) is compared to atmel_port->irq_status_prev. > Hence, a status-change of the CTS line is faultily detected. > > Both cases were verified on 9260 hardware.

2009-02-18atmel-mci: fix initialization of dma slave dataDan Williams
The conversion of atmel-mci to dma_request_channel missed the initialization of the channel dma_slave information. The filter_fn passed to dma_request_channel is responsible for initializing the channel's private data. This implementation has the additional benefit of enabling a generic client-channel data passing mechanism.

2009-02-18lis3lv02d: support both one- and two-byte sensorsGiuseppe Bilotta
Sensors responding with 0x3B to WHO_AM_I only have one data register per direction, thus returning a signed byte from the position which is occupied by the MSB in sensors responding with 0x3A. Since multiple sensors share the reply to WHO_AM_I, we rename the defines to better indicate what they identify (family of single and double precision sensors). We support both kind of sensors by checking for the sensor type on init and defining appropriate data-access routines and sensor limits (for the joystick) depending on what we find.

2009-02-17USB/PCI: Fix resume breakage of controllers behind cardbus bridgesRafael J. Wysocki
If a USB PCI controller is behind a cardbus bridge, we are trying to restore its configuration registers too early, before the cardbus bridge is operational. To fix this, call pci_restore_state() from usb_hcd_pci_resume() and remove usb_hcd_pci_resume_early() which is no longer necessary (the configuration spaces of USB controllers that are not behind cardbus bridges will be restored by the PCI PM core with interrupts disabled anyway). This patch fixes the regression from 2.6.28 tracked as http://bugzilla.kernel.org/show_bug.cgi?id=12659 [ Side note: the proper long-term fix is probably to just force the unplug event at suspend time instead of doing a plug/unplug at resume time, but this patch is fine regardless - Linus ] Signed-off-by: Rafael J.

2009-02-17Fix Intel IOMMU write-buffer flushingDavid Woodhouse
This is the cause of the DMA faults and disk corruption that people have been seeing. Some chipsets neglect to report the RWBF "capability" -- the flag which says that we need to flush the chipset write-buffer when changing the DMA page tables, to ensure that the change is visible to the IOMMU. Override that bit on the affected chipsets, and everything is happy again. Thanks to Chris and Bhavesh and others for helping to debug.

As reported by David Engel <david@istwok.net>, ATSC115 doesn't work fine with mythtv. This software opens both analog and dvb interfaces of saa7134. What happens is that some tuner commands are going to the wrong place, as shown at the logs: Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: using tuner params #0 (ntsc) Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: freq = 67.25 (1076), range = 0, config = 0xce, cb = 0x01 Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: Freq= 67.25 MHz, V_IF=45.75 MHz, Offset=0.00 MHz, div=1808 Feb 12 20:37:48 opus kernel: tuner 1-0061: tv freq set to 67.25 Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: using tuner params #0 (ntsc) Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: freq = 67.25 (1076), range = 0, config = 0xce, cb = 0x01 Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: Freq= 67.25 MHz, V_IF=45.75 MHz, Offset=0.00 MHz, div=1808 Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: tv 0x07 0x10 0xce 0x01 Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: tv 0x07 0x10 0xce 0x01 This happens due to a hack at TUV1236D analog setup, where it replaces tuner address, at 0x61 for 0x0a, in order to save a few memory bytes. The code assumes that nobody else would try to access the tuner during that setup, but the point is that there's no lock to protect such access. So, this opens the possibility of race conditions to happen. Instead of hacking tuner address, this patch uses a temporary var with the proper tuner value to be used during the setup. This should save the issue, although we should consider to write some analog/digital lock at saa7134 driver. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2009-02-16libata-sff: fix 32-bit PIO ATAPI regressionSergei Shtylyov
Commit 871af1210f13966ab911ed2166e4ab2ce775b99d (libata: Add 32bit PIO support) has caused all kinds of errors on the ATAPI devices, so it has been empirically proven that one shouldn't try to read/write an extra data word when a device is not expecting it already. "Don't do it then"; however, still use a chance to do 32-bit read/write one last time when there are exactly 3 trailing bytes. Oh, and stop pointlessly swapping the bytes to and fro on big-endian machines by using io*_rep() accessors which shouldn't byte-swap. This patch should fix the kernel.org bug #12609.

2009-02-14iommu: fix Intel IOMMU write-buffer flushingDavid Woodhouse
This is the cause of the DMA faults and disk corruption that people have been seeing. Some chipsets neglect to report the RWBF "capability" -- the flag which says that we need to flush the chipset write-buffer when changing the DMA page tables, to ensure that the change is visible to the IOMMU. Override that bit on the affected chipsets, and everything is happy again. Thanks to Chris and Bhavesh and others for helping to debug.
