2009-05-27i915: Set object to gtt domain when faulting it back inKristian Høgsberg
When a GEM object is evicted from the GTT we set it to the CPU domain, as it might get swapped in and out or ever mmapped regularly. If the object is mmapped through the GTT it can still get evicted in this way by other objects requiring GTT space. When the GTT mapping is touched again we fault it back into the GTT, but fail to set it back to the GTT domain. This means we fail to flush any cached CPU writes to the pages backing the object which will then happen "eventually", typically after we write to the page through the uncached GTT mapping. [anholt: Note that userland does do a set_domain(GTT, GTT) when starting to access the GTT mapping. That covers getting the existing mapping of the object synchronized if it's bound to the GTT. But set_domain(GTT, GTT) doesn't do anything if the object is currently unbound. This fix covers the transition to being bound for GTT mapping.] Fixes glyph and other pixmap corruption during swapping. fd.o bug #21790 Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Eric Anholt <eric@anholt.net>
2009-05-26drm/i915: Apply a big hammer to 865 GEM object CPU cache flushing.Eric Anholt
On the 865, but not the 855, the clflush we do appears to not actually make it out to the hardware all the time. An easy way to safely reproduce was X -retro, which would show that some of the blits involved in drawing the lovely root weave didn't make it out to the hardware. Those blits are 32 bytes each, and 1-2 would be missing at various points around the screen. Other experimentation (doing more clflush, doing more AGP chipset flush, poking at some more device registers to maybe trigger more flushing) didn't help. krh came up with the wbinvd as a way to successfully get all those blits to appear.

2009-05-26drm/i915: Fix tiling pitch handling on 8xx.Eric Anholt
The pitch field is an exponent on pre-965, so we were rejecting buffers on 8xx that we shouldn't have. 915 got lucky in that the largest legal value happened to match (8KB / 512 = 0x10), but 8xx has a smaller tile width. Additionally, we programmed that bad value into the register on 8xx, so the only pitch that would work correctly was 4096 (512-1023 pixels), while others would probably give bad rendering or hangs.

The rwlock seems to be taken around the whole call to cpufreq_governor_dbs(), when it should be only taken around accesses to the locked data, and especially *not* around the call to dbs_timer_exit(). Reverting my fix attempt would put the teardown race back in place (replacing the cancel_delayed_work_sync by cancel_delayed_work). Instead, a proper fix would imply modifying this critical section : cpufreq.c: __cpufreq_remove_dev() ... if (cpufreq_driver->target) __cpufreq_governor(data, CPUFREQ_GOV_STOP); unlock_policy_rwsem_write(cpu); To make sure the __cpufreq_governor() callback is not called with rwsem held. This would allow execution of cancel_delayed_work_sync() without being nested within the rwsem. Applies on top of the 2.6.30-rc5 tree. Required to remove circular dep in teardown of both conservative and ondemande governors so they can use cancel_delayed_work_sync(). CPUFREQ_GOV_STOP does not modify the policy, therefore this locking seemed unneeded.

2009-05-25r8169: avoid losing MSI interruptsDavid Dillow
The 8169 chip only generates MSI interrupts when all enabled event sources are quiescent and one or more sources transition to active. If not all of the active events are acknowledged, or a new event becomes active while the existing ones are cleared in the handler, we will not see a new interrupt. The current interrupt handler masks off the Rx and Tx events once the NAPI handler has been scheduled, which opens a race window in which we can get another Rx or Tx event and never ACK'ing it, stopping all activity until the link is reset (ifconfig down/up). Fix this by always ACK'ing all event sources, and loop in the handler until we have all sources quiescent.

2009-05-26md: don't update curr_resync_completed without also updating reshape_position.NeilBrown
In order for the metadata to always be consistent, we mustn't updated curr_resync_completed without also updating reshape_position. The reshape code updates both at the same time. However since commit 97e4f42d62badb0f9fbc27c013e89bc1336a03bc the common md_do_sync will sometimes update curr_resync_completed but is not in a position to update reshape_position. So if MD_RECOVERY_RESHAPE is set (indicating that a reshape is happening, so reshape_position might change), don't update curr_resync_completed in md_do_sync, leave it to the per-personality reshape code.

2009-05-25gianfar: fix BUG under load after introduction of skb recyclingLennert Buytenhek
Since commit 0fd56bb5be6455d0d42241e65aed057244665e5e ("gianfar: Add support for skb recycling"), gianfar puts skbuffs that are in the rx ring back onto the recycle list as-is in case there was a receive error, but this breaks the following invariant: that all skbuffs on the recycle list have skb->data = skb->head + NET_SKB_PAD. The RXBUF_ALIGNMENT realignment done in gfar_new_skb() will be done twice on skbuffs recycled in this way, causing there not to be enough room in the skb anymore to receive a full packet, eventually leading to an skb_over_panic from gfar_clean_rx_ring() -> skb_put(). Resetting the skb->data pointer to skb->head + NET_SKB_PAD before putting the skb back onto the recycle list restores the mentioned invariant, and should fix this issue.

2009-05-24PM: Do not hold dpm_list_mtx while disabling/enabling nonboot CPUsRafael J. Wysocki
We shouldn't hold dpm_list_mtx while executing [disable|enable]_nonboot_cpus(), because theoretically this may lead to a deadlock as shown by the following example (provided by Johannes Berg): CPU 3 CPU 2 CPU 1 suspend/hibernate something: rtnl_lock() device_pm_lock() -> mutex_lock(&dpm_list_mtx) mutex_lock(&dpm_list_mtx) linkwatch_work -> rtnl_lock() disable_nonboot_cpus() -> flush CPU 3 workqueue Fortunately, device drivers are supposed to stop any activities that might lead to the registration of new device objects way before disable_nonboot_cpus() is called, so it shouldn't be necessary to hold dpm_list_mtx over the entire late part of device suspend and early part of device resume. Thus, during the late suspend and the early resume of devices acquire dpm_list_mtx only when dpm_list is going to be traversed and release it right after that.

2009-05-22drm/i915: Use an I2C algo to do the flip to SDVO DDC bus.Ma Ling
Previously, we would set the control bus switch before calls were made to request EDID information over DDC. But recently the DDC code started doing multiple I2C transfers to get the EDID extensions as well. This tripped up SDVO, because the control bus switch is only in effect until the next STOP after a START. By doing our own algo, we can wrap each i2c transaction on the DDC I2C bus with the control bus switch it requires. freedesktop.org bug #21042 Signed-off-by: Ma Ling <ling.ma@intel.com> [anholt: Hand application for conflict, fixed error path] Signed-off-by: Eric Anholt <eric@anholt.net>
2009-05-22drm/i915: Determine type before initialising connectorJonas Bonn
drm_connector_init sets both the connector type and the connector type_id on the newly initialised connector. As the connector type_id is coupled to the connector type, the connector type cannot simply be modified on an initialised connector. This patch changes the order of operations on intel_sdvo_init so that the type is determined before the connector is intialised. This fixes a bug whereby the name card0-VGA-1 would be allocted to both a CRT and an SDVO connector since the SDVO connector would be initialised with type 'unknown' and hence have its type_id assigned from the wrong pool.

2009-05-22ipmi: fix ipmi_si modprobe hangCorey Minyard
Instead of queuing IPMB messages before channel initialization, just throw them away. Nobody will be listening for them at this point, anyway, and they will clog up the queue and nothing will be delivered if we queue them. Also set the current channel to the number of channels, as this value is used to tell if the channel information has been initialized.

It is possible for ide-cd to ignore ide_error()'s return value under some circumstances. Workaround it in ide_intr() and ide_timer_expiry() by checking if there is a device/port reset pending currently.

2009-05-22ide: fix 40-wire cable detection for TSST SH-S202* ATAPI devices (v2)Bartlomiej Zolnierkiewicz
Since 2.6.26 we support UDMA66 on ATAPI devices requiring IVB quirk: commit 8588a2b732928b343233af9b1855705b8286bed4 ("ide: add SH-S202J to ivb_list[]") We also later added support for more such devices in: commit e97564f362a93f8c248246c19828895950341252 ("ide: More TSST drives with broken cable detection") and in: commit 3ced5c49bd2d1f2c7f769e3a54385883de63a652 ("ide: add TSSTcorp CDDVDW SH-S202H to ivb_list[]") It turns out that such devices lack cable detection altogether (which in turn results in incorrect detection of 40-wire cables by our current cable detection strategy) so always handle them by trusting host-side cable detection only. v2: Model detection fixup from Martin.

2009-05-22wimax/i2400m: usb: fix device reset on autosuspend while not yet idleInaky Perez-Gonzalez
When the i2400m is connected to a network, the host interface (USB) cannot be suspended. For that to happen, the device has to have negotiated with the basestation to put the link on IDLE state. If the host tries to put the device in standby while it is connected but not idle, the device resets, as the driver should not do that. To avoid triggering that, when the USB susbsytem requires the driver to autosuspend the device, the driver checks if the device is not yet idle. If it is not, the request is rejected (will be retried again later on after the autosuspend timeout). At some point the device will enter idle and the request will succeed (unless of course, there is network traffic, but at that point, there is no idle neither in the link or the host interface).

The second argument of the probe method points to the amba_id structure, so it's better passed with the correct type. None of the current in-tree drivers uses the pointer, so they have only been checked for a clean compile. Change suggested by Russell King.
