2010-08-03OMAP: DSS2: OMAPFB: Add some locking debug checksVille Syrjälä
Trigger WARN_ON() messages from various places in the code in case the memory region is not currently locked. Signed-off-by: Ville Syrjälä <ville.syrjala@nokia.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>
2010-08-03OMAP: DSS2: OMAPFB: Make lockdep happyVille Syrjälä
When more than one memory region needs to be lockd at the same time use the memory region id to fix the order in which the locks are taken. Also one needs to use the _nested() versions of the locking primitives. The memory region id can serve as the lock class there as well.

2010-08-03OMAP: DSS2: OMAPFB: Convert the memory region locking to rwsemVille Syrjälä
R/W semaphore is a good fit for the memory region locking pattern. So use it. Signed-off-by: Ville Syrjälä <ville.syrjala@nokia.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>
2010-08-03OMAP: DSS2: OMAPFB: Add locking for memory regionsVille Syrjälä
Add locking to the memory regions to make sure the memory region size won't be changed while some other piece of code is performing some checks or setup based on that information. Signed-off-by: Ville Syrjälä <ville.syrjala@nokia.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>
2010-08-03OMAP: DSS2: OMAPFB: Add support for switching memory regionsVille Syrjälä
Separate the memory region from the framebuffer device a little bit. It's now possible to select the memory region used by the framebuffer device using the new mem_idx parameter of omapfb_plane_info. If the mem_idx is specified it will be interpreted as an index into the memory regions array, if it's not specified the framebuffer's index is used instead. So by default each framebuffer keeps using it's own memory region which preserves backwards compatibility. This allows cloning the same memory region to several overlays and yet each overlay can be controlled independently since they can be associated with separate framebuffer devices.

2010-08-03OMAP: DSS2: OMAPFB: Skip unnecessary set_overlay_info()Ville Syrjälä
In omapfb_enable_overlay() if the overlay state is already what we want skip the set_overlay_info(). Signed-off-by: Ville Syrjälä <ville.syrjala@nokia.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>
2010-08-03OMAP: DSS2: OMAPFB: Check var even if there isn't memoryVille Syrjälä
If video memory hasn't been allocate have check_fb_var() still check most of the settings, just skip the ones involving the size of the memory region. Also skip the memory address calculations in omapfb_setup_overlay() if there's no memory.

2010-08-03OMAP: DSS2: OMAPFB: Refactor overlay address calculationsVille Syrjälä
Split the overlay address calculations into their own function. Signed-off-by: Ville Syrjälä <ville.syrjala@nokia.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>
2010-08-03OMAP: DSS2: Fix update area calculations with multiple scaled overlaysTomi Valkeinen
When there are multiple scaled overlays simply checking whether the update area intersects any of them in order is not enough. If eg. VID1 starts out completely outside the update area but VID2 causes the update area to increase in such a way that VID1 now falls partially within the increased update area VID1 should be rechecked and the update area possibly increased even further to fully encompass VID1. So simply keep looping over the overlays until such time that none of the overlays caused the update area to change.

2010-08-03OMAP: DSS2: clear spurious SYNC_LOST_DIGIT interruptsVille Syrjälä
When DSS transitions from off mode to on VENC may generate a spurious SYNC_LOST_DIGIT error. Just ack it when restoring the context. Also restore IRQENABLE last to avoid triggering interrupts before the context is fully restored.

2010-08-03OMAP: DSS2: Make wait_for_go() succeed for disabled displaysVille Syrjälä
When the display is not active make the wait_for_go() functions return immediately. Signed-off-by: Ville Syrjälä <ville.syrjala@nokia.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>
2010-08-03OMAP: DSS2: Check if display supports update mode changesVille Syrjälä
Check whether the display actually has the set_update_mode() function before calling it. Only the sysfs codepath was broken, the omapfb ioctl had the necessary protection. Signed-off-by: Ville Syrjälä <ville.syrjala@nokia.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@nokia.com>
2010-08-03OMAP: DSS2: DSI: Increase HS TX timeoutTomi Valkeinen
For some reason screen updates of certain odd widths seem to be triggering HS TX timeouts on OMAP 3430, even if bigger updates do not. The reason for this is unknown, but increasing the timeout removes the problem with no (so far) noticeable problems. I haven't seen this problem on OMAP 3630.

2010-08-02e1000e: register pm_qos request on hardware activationFlorian Mickler
The pm_qos_add_request call has to register the pm_qos request with the pm_qos susbsystem before first use of the pm_qos request via pm_qos_update_request. As pm_qos changed to use plists there is no benefit in registering and unregistering the pm_qos request on ifup/ifdown and thus we move the registering into e1000_open and the unregistering in e1000_close. This fixes the following warning: [ 1.786060] WARNING: at kernel/pm_qos_params.c:264 pm_qos_update_request+0x28/0x54() [ 1.786088] Hardware name: Latitude E6500 [ 1.787045] pm_qos_update_request() called for unknown object [ 1.787966] Modules linked in: [ 1.788940] Pid: 1, comm: swapper Not tainted 2.6.35-rc5-mmotm0719 #1 [ 1.790035] Call Trace: [ 1.791121] [<ffffffff81037335>] warn_slowpath_common+0x80/0x98 [ 1.792205] [<ffffffff810373e1>] warn_slowpath_fmt+0x41/0x43 [ 1.793279] [<ffffffff81057c14>] pm_qos_update_request+0x28/0x54 [ 1.794347] [<ffffffff8134889e>] e1000_configure+0x421/0x459 [ 1.795393] [<ffffffff8134afbd>] e1000_open+0xbd/0x37c [ 1.796436] [<ffffffff8105743a>] ? raw_notifier_call_chain+0xf/0x11 [ 1.797491] [<ffffffff8145f948>] __dev_open+0xae/0xe2 [ 1.798547] [<ffffffff8145f997>] dev_open+0x1b/0x49 [ 1.799612] [<ffffffff8146e36e>] netpoll_setup+0x84/0x259 [ 1.800685] [<ffffffff81b5037c>] init_netconsole+0xbc/0x21f [ 1.801744] [<ffffffff81b5026c>] ? sir_wq_init+0x0/0x35 [ 1.802793] [<ffffffff81b502c0>] ? init_netconsole+0x0/0x21f [ 1.803845] [<ffffffff810002ff>] do_one_initcall+0x7a/0x12f [ 1.804885] [<ffffffff81b2ccae>] kernel_init+0x138/0x1c2 [ 1.805915] [<ffffffff81003554>] kernel_thread_helper+0x4/0x10 [ 1.806937] [<ffffffff81590e00>] ? restore_args+0x0/0x30 [ 1.807955] [<ffffffff81b2cb76>] ? kernel_init+0x0/0x1c2 [ 1.808958] [<ffffffff81003550>] ? kernel_thread_helper+0x0/0x10 [ 1.809958] ---[ end trace 84b562a00a60539e ]--- Signed-off-by: Florian Mickler <florian@mickler.org> Tested-by: Valdis Kletnieks <valdis.kletnieks@vt.edu> Tested-by: Jeff Pieper <jeffrey.e.pieper@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S.

2010-08-02RDMA/cxgb4: Fix race in fini pathSteve Wise
There exists a race condition where the app disconnects, which initiates an orderly close (via rdma_fini()), concurrently with an ingress abort condition, which initiates an abortive close operation. Since rdma_fini() must be called without IRQs disabled, the fini can be called after the QP has been transitioned to ERROR. This is ok, but we need to protect against qp->ep getting NULLed.

The kpad structure is assigned to i2c client via i2s_set_clientdata() at the end of adp5588_probe(), but in adp5588_gpio_add() we tried to access it (via dev_get_drvdata! which is not nice at all) causing an oops. Let's pass pointer to kpad directly into adp5588_gpio_add() and adp5588_gpio_remove() to avoid accessing driver data before it is set up.

If multiple devices have to exist on a given platform, multiple ST platform devices need to be registered and each of the protocol drivers have to mention which platform device they want to bind to/make use of.
