2010-09-07VFS: Sanity check mount flags passed to change_mnt_propagation()Valerie Aurora1-1/+22
Sanity check the flags passed to change_mnt_propagation(). Exactly one flag should be set. Return EINVAL otherwise. Userspace can pass in arbitrary combinations of MS_* flags to mount(). do_change_type() is called if any of MS_SHARED, MS_PRIVATE, MS_SLAVE, or MS_UNBINDABLE is set. do_change_type() clears MS_REC and then calls change_mnt_propagation() with the rest of the user-supplied flags. change_mnt_propagation() clearly assumes only one flag is set but do_change_type() does not check that this is true. For example, mount() with flags MS_SHARED | MS_RDONLY does not actually make the mount shared or read-only but does clear MNT_UNBINDABLE.

2010-09-07drm/i915: Avoid pageflipping freeze when we miss the flip prepare interruptSimon Farnsworth4-12/+113
When we miss the flip prepare interrupt, we never get into the software state needed to restart userspace, resulting in a freeze of a full-screen OpenGL application (such as a compositor). Work around this by checking DSPxSURF/DSPxBASE to see if the page flip has actually happened. If it has, do the work we would have done when the flip prepare interrupt comes in. Also, add debugfs information to tell us what's going on (based on the patch from Chris Wilson attached to bugs.fdo bug #29798).

2010-09-07drm/i915: Tightly scope intel_encoder to prevent invalid useChris Wilson1-13/+12
We reset intel_encoder for every matching encoder whilst iterating over the encoders attached to this crtc when changing mode. As such in a cloned configuration intel_encoder may not correspond to the correct is_edp encoder. By scoping intel_encoder to the loop, not only is the compiler able to spot this mistake, we also improve readiability for ourselves.

2010-09-06drm/i915: overlay on gen2 can't address above 1GDaniel Vetter1-0/+4
So set the coherent dma mask accordingly. This dma mask is only used for physical objects, so it won't really matter allocation-wise. Now this never really surfaced because sane 32bit kernels only have 1G of lowmem. But some eager testers (distros?) still carry around the patch to adjust lowmem via a kconfig option. And the kernel seems to favour high allocations on boot-up, hence the overlay blowing up reliably. Because the patch is tiny and nicely shows how broken gen2 is it's imho worth to merge despite the fact that mucking around with the lowmem/ highmem division is (no longer) supported.

2010-09-07drm: Do not force 1024x768 modes on unknown connectorsChris Wilson1-4/+3
Only fallback to a set of default modes on a connector iff that connector is known to be connected. The issue occurs that with limited hardware which cannot probe a connector and so reports the connector status as unknown will then attempt to retrieve the modes for it during drm_helper_probe_single_connector_modes(). Should that fail, the helper then generates a default set which fools the fb_helper and causes havoc with the console and beyond.

2010-09-07drm/kms: Add a module parameter to disable pollingChris Wilson1-2/+15
Polling for a VGA device on an old system can be quite expensive, causing latencies on the order of 600ms. As we hold the mode mutex for this time and also need the same mutex to move the cursor, we trigger a user-visible stall. The real solution would involve improving the granulatity of the locking and so perhaps performing some of the probing not under the lock or some other updates can be done under different locks. Also reducing the cost of probing for a non-existent monitor would be worthwhile. However, exposing a parameter to disable polling is a simple workaround in the meantime. In order to accommodate users turning polling on and off at runtime, the polling is potentially re-enabled on every probe. This is coupled to the user calling xrandr, which seems to be a vaild time to reset the polling timeout since the information on the connection has just been updated. (The presumption being that all connections are probed in a single xrandr pass, which is currently valid.)

If the ACM driver is forced to probe all interfaces on a device the a NULL pointer dereference will occur when the ACM driver attempts to use the endpoint of the alternative settings. One way to get the ACM driver to probe all the interfaces is by using the /sys/bus/usb/drivers/cdc_acm/new_id interface.

2010-09-03usb: allow drivers to use allocated bandwidth until unboundThadeu Lima de Souza Cascardo1-11/+11
When using the remove sysfs file, the device configuration is set to -1 (unconfigured). This eventually unbind drivers with the bandwidth_mutex held. Some drivers may call functions that hold said mutex, like usb_reset_device. This is the case for rtl8187, for example. This will lead to the same process holding the mutex twice, which deadlocks. Besides, according to Alan Stern: "The deadlock problem probably could be handled somehow, but there's a separate issue: Until the usb_disable_device call finishes unbinding the drivers, the drivers are free to continue using their allocated bandwidth. We musn't change the bandwidth allocations until after the unbinding is done. So this patch is indeed necessary." Unbinding the driver before holding the bandwidth_mutex solves the problem. If any operation after that fails, drivers are not bound again. But that would be a problem anyway that the user may solve resetting the device configuration to one that works, just like he would need to do in most other failure cases.

2010-09-03USB: cp210x usb driver: add USB_DEVICE for Pirelli DP-L10 mobile.A E Lawrence1-0/+1
The Pirelli DP-L10 mobile is sold under various brand names. One, already supported by cp210x, is the T-COM TC300. Here is the lsusb for that version: ------------------------------------------------------------------- Bus 001 Device 002: ID 0489:e000 Foxconn / Hon Hai T-Com TC 300 Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.10 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0x0489 Foxconn / Hon Hai idProduct 0xe000 T-Com TC 300 bcdDevice 1.00 iManufacturer 1 Silicon Labs iProduct 2 TC 300 iSerial 3 0001 [snip] --------------------------------------------------------------------------- However the native Pirelli DP-L10 is not supported: ------------------------------------------------------------------ Bus 001 Device 003: ID 0489:e003 Foxconn / Hon Hai Pirelli DP-L10 Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.10 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0x0489 Foxconn / Hon Hai idProduct 0xe003 Pirelli DP-L10 bcdDevice 1.00 iManufacturer 1 Silicon Labs iProduct 2 DP-L10 iSerial 3 0001 [snip] ------------------------------------------------------------------------- All that is required is an extra USB_DEVICE entry: { USB_DEVICE(0x0489, 0xE003) }, /* Pirelli Broadband S.p.A, DP-L10 SIP/GSM +Mobile */ The patch adds that entry.
