* PM / Domains: Allow generic PM domains to have multiple mastersRafael J. Wysocki2011-08-252-44/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, for a given generic PM domain there may be only one parent domain (i.e. a PM domain it depends on). However, there is at least one real-life case in which there should be two parents (masters) for one PM domain (the A3RV domain on SH7372 turns out to depend on the A4LC domain and it depends on the A4R domain and the same time). For this reason, allow a PM domain to have multiple parents (masters) by introducing objects representing links between PM domains. The (logical) links between PM domains represent relationships in which one domain is a master (i.e. it is depended on) and another domain is a slave (i.e. it depends on the master) with the rule that the slave cannot be powered on if the master is not powered on and the master cannot be powered off if the slave is not powered off. Each struct generic_pm_domain object representing a PM domain has two lists of links, a list of links in which it is a master and a list of links in which it is a slave. The first of these lists replaces the list of subdomains and the second one is used in place of the parent pointer. Each link is represented by struct gpd_link object containing pointers to the master and the slave and two struct list_head members allowing it to hook into two lists (the master's list of "master" links and the slave's list of "slave" links). This allows the code to get to the link from each side (either from the master or from the slave) and follow it in each direction. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
* PM / Domains: Add "wait for parent" status for generic PM domainsRafael J. Wysocki2011-08-252-30/+61
| | | | | | | | | | | | | | | | | | | | The next patch will make it possible for a generic PM domain to have multiple parents (i.e. multiple PM domains it depends on). To prepare for that change it is necessary to change pm_genpd_poweron() so that it doesn't jump to the start label after running itself recursively for the parent domain. For this purpose, introduce a new PM domain status value GPD_STATE_WAIT_PARENT that will be set by pm_genpd_poweron() before calling itself recursively for the parent domain and modify the code in drivers/base/power/domain.c so that the GPD_STATE_WAIT_PARENT status is guaranteed to be preserved during the execution of pm_genpd_poweron() for the parent. This change also causes pm_genpd_add_subdomain() and pm_genpd_remove_subdomain() to wait for started pm_genpd_poweron() to complete and allows pm_genpd_runtime_resume() to avoid dropping the lock after powering on the PM domain.

* PM / Domains: Make pm_genpd_poweron() always survive parent removalRafael J. Wysocki2011-08-251-13/+20
| | | | | | | | | | | | | | If pm_genpd_remove_subdomain() is called to remove a PM domain's subdomain and pm_genpd_poweron() is called for that subdomain at the same time, and the pm_genpd_poweron() called by it recursively for the parent returns an error, the first pm_genpd_poweron()'s error code path will attempt to decrement the subdomain counter of a PM domain that it's not a subdomain of any more. Rearrange the code in pm_genpd_poweron() to prevent this from happening. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
* PM / Domains: Do not take parent locks to modify subdomain countersRafael J. Wysocki2011-08-251-39/+31
| | | | | | | | | | | After the subdomain counter in struct generic_pm_domain has been changed into an atomic_t field, it is possible to modify pm_genpd_poweron() and pm_genpd_poweroff() so that they don't take the parents locks. This requires pm_genpd_poweron() to increment the parent's subdomain counter before calling itself recursively for the parent and to decrement it if an error is to be returned.

* PM / Domains: Implement subdomain counters as atomic fieldsRafael J. Wysocki2011-08-252-11/+21
| | | | | | | | | | | | | | | | | | Currently, pm_genpd_poweron() and pm_genpd_poweroff() need to take the parent PM domain's lock in order to modify the parent's counter of active subdomains in a nonracy way. This causes the locking to be considerably complex and in fact is not necessary, because the subdomain counters may be implemented as atomic fields and they won't have to be modified under a lock. Replace the unsigned in sd_count field in struct generic_pm_domain by an atomic_t one and modify the code in drivers/base/power/domain.c to take this change into account. This patch doesn't change the locking yet, that is going to be done in a separate subsequent patch. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
* OMAP: omap_device: only override _noirq methods, not normal suspend/resumeKevin Hilman2011-08-251-1/+2
| | | | | | | | | | | | | | | | | | Commit c03f007a8bf0e092caeb6856a5c8a850df10b974 (OMAP: PM: omap_device: add system PM methods for PM domain handling) mistakenly used SET_SYSTEM_SLEEP_PM_OPS() when trying to configure custom methods for the PM domains noirq methods. Fix that by setting only the suspend_noirq and resume_noirq methods with custom versions. Note that all other PM domain methods (including the "normal" suspend/resume methods) are populated using USE_PLATFORM_PM_SLEEP_OPS, which configures them all to the default subsystem (platform_bus) methods.

* ARM: mach-shmobile: sh7372 LCDC1 suspend fixMagnus Damm2011-08-243-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | Associate the HDMI clock together with LCDC1 on sh7372. Without this patch Suspend-to-RAM hangs on the boards AP4EVB and Mackerel. The code hangs in the LCDC driver where the software is waiting forever for the hardware to power down. By explicitly associating the HDMI clock with LCDC1 we can make sure the HDMI clock is enabled using Runtime PM whenever the driver is accessing the hardware. This HDMI and LCDC1 dependency is documented in the sh7372 data sheet. Older kernels did work as expected but the recently merged (3.1-rc) 794d78f drivers: sh: late disabling of clocks V2 introduced code to turn off clocks lacking software reference which happens to include the HDMI clock that is needed by LCDC1 to operate as expected.

To let the driver choose the DRM mode, pass WIIPROTO_REQ_NULL placeholder to it. This is no valid request and is replaced with an appropriate DRM. Currently, the driver always sets the basic DRM_K mode, but this will be extended when further peripherals like accelerometer and IR are supported.

The last one invalidates the original premise of the patch that flock locks can be emulated with POSIX locks. This patch fixes the first two issues. The last one needs to be fixed in userspace if the filesystem assumed that a write lock will happen only on a file operned for write (as in the case of the current fuse library).

Add a register window save area in the signal frame, and store any unsavable windows there. On sigreturn, if any windows are still queued up in the signal frame, try to push them back onto the stack and if that fails we kill the process immediately. This allows the debug/tst-longjmp_chk2 glibc test case to pass. Signed-off-by: David S. Miller <davem@davemloft.net>
