2011-11-18OMAPDSS: DISPC: skip scaling calculations when not scalingTomi Valkeinen
Current code calculates scaling factors for video overlays even when the overlays are not scaled. Change the code to skip calculations when not scaling. This optimizes the code a bit, but also fixes a problem when configuring an overlay for a disabled display: if the display is disabled we don't necessarily know the pixel clock used when the display is enabled, and in some cases (like HDMI) the pixel clock is set to zero until a proper video mode is set later. A wrong pixel clock will mess up the scaling calculations, causing an error like: omapdss DISPC error: failed to set up scaling, required fclk rate = 0 Hz, current fclk rate = 170666666 Hz A proper fix would be to check later whether the clocks are enough for the scaling, at the point when the overlay or display is actually enabled, but this patch removes the problem for now.

2011-11-17drm/i915: Fix inconsistent backlight level during disabledTakashi Iwai
When the brightness property is inquired while the backlight is disabled, the driver returns a wrong value (zero) because it probes the value after the backlight was turned off. This caused a black screen even after the backlight is enabled again. It should return the internal backlight_level instead, so that it won't be influenced by the backlight-enable state.

2011-11-17pstore: pass allocated memory region back to callerKees Cook
The buf_lock cannot be held while populating the inodes, so make the backend pass forward an allocated and filled buffer instead. This solves the following backtrace. The effect is that "buf" is only ever used to notify the backends that something was written to it, and shouldn't be used in the read path. To replace the buf_lock during the read path, isolate the open/read/close loop with a separate mutex to maintain serialized access to the backend. Note that is is up to the pstore backend to cope if the (*write)() path is called in the middle of the read path.

2011-11-17PM Sleep: Do not extend wakeup paths to devices with ignore_children setRafael J. Wysocki
Commit 4ca46ff3e0d8c234cb40ebb6457653b59584426c (PM / Sleep: Mark devices involved in wakeup signaling during suspend) introduced the power.wakeup_path field in struct dev_pm_info to mark devices whose children are enabled to wake up the system from sleep states, so that power domains containing the parents that provide their children with wakeup power and/or relay their wakeup signals are not turned off. Unfortunately, that introduced a PM regression on SH7372 whose power consumption in the system "memory sleep" state increased as a result of it, because it prevented the power domain containing the I2C controller from being turned off when some children of that controller were enabled to wake up the system, although the controller was not necessary for them to signal wakeup. To fix this issue use the observation that devices whose power.ignore_children flag is set for runtime PM should be treated analogously during system suspend. Namely, they shouldn't be included in wakeup paths going through their children. Since the SH7372 I2C controller's power.ignore_children flag is set, doing so will restore the previous behavior of that SOC. Signed-off-by: Rafael J.

2011-11-17TTY: ldisc, wait for ldisc infinitely in hangupJiri Slaby
For /dev/console case, we do not kill all ldisc users. It's due to redirected_tty_write test in __tty_hangup. In that case there still might be a process waiting e.g. in n_tty_read for input. We wait for such processes to disappear. The problem is that we use a timeout. After this timeout, we continue closing the ldisc and start freeing tty resources. It obviously leads to crashes when the other process is woken. So to fix this, we wait infinitely before reiniting the ldisc. (The tiocsetd remains untouched -- times out after 5s.) This is nicely reproducible with this run from shell: exec 0<>/dev/console 1<>/dev/console 2<>/dev/console and stopping a getty like: systemctl stop serial-getty@ttyS0.service The crash proper may be produced only under load or with constified timing the same as for 92f6fa09b.

This patch removes un-needed spin_lock in stmmac_ioctl while reading and writing mdio registers. While holding spin_lock the code must be atomic, which is not true in this case as both mdiobus_read and writes have mutex locks. Without this patch reading mdio registers via mii-tool results in below BUG: mii-tool -vvv eth0" Using SIOCGMIIPHY=0x8947 BUG: sleeping function called from invalid context at kernel/mutex.c:287 in_atomic(): 1, irqs_disabled(): 0, pid: 614, name: mii-tool 2 locks held by mii-tool/614: #0: (rtnl_mutex){......}, at: [<c01fd80c>] dev_ioctl+0x550/0x674 #1: (&priv->lock){......}, at: [<c01b34ec>] stmmac_ioctl+0x4c/0x78 [<c002ea14>] (unwind_backtrace+0x0/0xcc) from [<c0272c38>] (mutex_lock_nested+0x24/0x35c) [<c0272c38>] (mutex_lock_nested+0x24/0x35c) from [<c01b237c>] (mdiobus_read+0x44/0x70) [<c01b237c>] (mdiobus_read+0x44/0x70) from [<c01b0c64>] (phy_mii_ioctl+0x4c/0x138) [<c01b0c64>] (phy_mii_ioctl+0x4c/0x138) from [<c01b34fc>] (stmmac_ioctl+0x5c/0x78) [<c01b34fc>] (stmmac_ioctl+0x5c/0x78) from [<c01fcec8>] (dev_ifsioc+0x2a4/0x2c8) [<c01fcec8>] (dev_ifsioc+0x2a4/0x2c8) from [<c01fd81c>] (dev_ioctl+0x560/0x674) [<c01fd81c>] (dev_ioctl+0x560/0x674) from [<c00c36e0>] (vfs_ioctl+0x2c/0x8c) [<c00c36e0>] (vfs_ioctl+0x2c/0x8c) from [<c00c4130>] (do_vfs_ioctl+0x530/0x578) [<c00c4130>] (do_vfs_ioctl+0x530/0x578) from [<c00c41ac>] (sys_ioctl+0x34/0x54) [<c00c41ac>] (sys_ioctl+0x34/0x54) from [<c0028aa0>] (ret_fast_syscall+0x0/0x2c) Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@st.com> Signed-off-by: Giuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: David S.

2011-11-17stmmac: parameters auto-tuning through HW cap regGiuseppe CAVALLARO
New GMAC devices (newer than the databook 3.50a) have the HW capability register that provides which features are actually supported by the hardware. On old devices many information have to be passed through the platform, for example: enhanced descriptor structure, TX COE etc. These are mandatory to properly configure the driver. This remains still valid because the driver has to support old Synopsys devices but now it's also able to override them using the values from the HW capability register if supported.

Limit the link training setting command to the lanes needed for the current mode. It seems vaguely possible that a monitor will try to train the other lanes and fail in some way, so this seems like the safer plan.

Instead of going through the sequence just once, run through the whole set up to 5 times to see if something can work. This isn't part of the DP spec, but the BIOS seems to do it, and given that link training failure is so bad, it seems reasonable to follow suit.
