2012-11-14KBuild: Allow scripts/* to be cross compiledlinaro-ubuntu-sauce-3.7John Rigby
Cross compiling the binaries in scripts/* is not possible because various makefiles assume that $(obj)/whatever is executable on the build host. This patch introduces a new variable called KBUILD_SCRIPTROOT that points to script/binaries to use while cross compiling. Usage: Build scripts for the build host: make O=path/to/buildhost/buildscripts \ silentoldconfig prepare scripts Then cross build script for target: make O=path/to/target/buildscripts \ HOSTCC=$CROSS_COMPILE \ KBUILD_SCRIPTROOT=path/to/buildhost/buildscripts silentoldconfig prepare scripts This patch does not use KBUILD_SCRIPTROOT for all script invocations it only redefines the following if KBUILD_SCRIPTROOT is defined. scripts/Makefile.build scripts/basic/fixdep --> $(KBUILD_SCRIPTROOT)/scripts/basic/fixdep scripts/kconfig/Makefile $(obj)/conf --> $(KBUILD_SCRIPTROOT)/scripts/kconfig/conf scripts/mod/Makefile $(obj)mk_elfconfig --> $(KBUILD_SCRIPTROOT)/scripts/mod/mk_elfconfig Signed-off-by: John Rigby <john.rigby@linaro.org>

2012-11-14UBUNTU: SAUCE: efivarfs: Implement exclusive access for {get, set}_variableJeremy Kerr
BugLink: http://bugs.launchpad.net/bugs/1063061 Currently, efivarfs does not enforce exclusion over the get_variable and set_variable operations. Section 7.1 of UEFI requires us to only allow a single processor to enter {get,set}_variable services at once. This change acquires the efivars->lock over calls to these operations from the efivarfs paths.

BugLink: http://bugs.launchpad.net/bugs/1063061 A write to an efivarfs file will not always result in a variable of 'count' size after the EFI SetVariable() call. We may have appended to the existing data (ie, with the EFI_VARIABLE_APPEND_WRITE attribute), or even have deleted the variable (with an authenticated variable update, with a zero datasize). This change re-reads the updated variable from firmware, to check for size changes and deletions. In the latter case, we need to drop the dentry.

2012-11-14UBUNTU: SAUCE: efi: Add support for a UEFI variable filesystemMatthew Garrett
BugLink: http://bugs.launchpad.net/bugs/1063061 The existing EFI variables code only supports variables of up to 1024 bytes. This limitation existed in version 0.99 of the EFI specification, but was removed before any full releases. Since variables can now be larger than a single page, sysfs isn't the best interface for this. So, instead, let's add a filesystem. Variables can be read, written and created, with the first 4 bytes of each variable representing its UEFI attributes. The create() method doesn't actually commit to flash since zero-length variables can't exist per-spec. Updates from Jeremy Kerr <jeremy.kerr@canonical.com>.

2012-11-14UBUNTU: SAUCE: input: fix weird issue of synaptics psmouse sync lost after ↵James M Leddy
resume BugLink: http://bugs.launchpad.net/bugs/717970 From: Eric Miao <eric.miao@canonical.com> This patch has already been sent upstream by Eric. Unfortunately, after a little back and forth between Eric and Dmitry Torokhov, the patch did get included, and there is still an open question to Dmitry. However, this is a known issue on at least 4 systems, and it causes them to lose their mouse device on suspend. So I was hoping we could get it in to quantal. Original email follows: So in summary, the symptom is intermittent key events lost after resume on some machines with synaptics touchpad (seems this is synaptics _only_), and key events loss is due to serio port reconnect after psmouse sync lost. Removing psmouse and inserting it back during the suspend/resume process is able to work around the issue, so the difference between psmouse_connect() and psmouse_reconnect() is the key to the root cause of this problem. After comparing the two different paths, synaptics driver has its own implementation of synaptics_reconnect(), and the missing psmouse_probe() seems significant, the patch below added psmouse_probe() to the reconnect process, and has been verified many times that the issue could not be reliably reproduced. There are two PS/2 commands in psmouse_probe(): 1. PSMOUSE_CMD_GETID 2. PSMOUSE_CMD_RESET_DIS The weird thing is, the PSMOUSE_CMD_GETID seems to be significant, and the PSMOUSE_CMD_RESET_DIS is irrelevant to this issue after trying several times. Now it's rather difficult to form a sane theory. So this patch is really for RFC. Note it does fix a real problem though. http://thread.gmane.org/gmane.linux.kernel.input/25599 Signed-off-by: James M Leddy <james.leddy@canonical.com> Acked-by: Seth Forshee <seth.forshee@canonical.com> Signed-off-by: Tim Gardner <tim.gardner@canonical.com>
