* gianfar: Do not call device_set_wakeup_enable() under a spinlockRafael J. Wysocki2010-11-12
| | | | | | | | | | | The gianfar driver calls device_set_wakeup_enable() under a spinlock, which causes a problem to happen after the recent core power management changes, because this function can sleep now. Fix this by moving the device_set_wakeup_enable() call out of the spinlock-protected area. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: David S. Miller <davem@davemloft.net>

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* gianfar: Add Multiple group SupportSandeep Gopalpet2009-11-03
| | | | | | | | | | | | | | | This patch introduces multiple group support for etsec2.0 devices. Multiple group support is provided by mapping the set of enabled queues to different groups and then programming the per group regsiters imask, ievent, rstat, tstat. The queues corresponding to a group are indicated by programming isrg (interrupt steering) registers. Signed-off-by: Sandeep Gopalpet <Sandeep.Kumar@freescale.com> Signed-off-by: David S.

* gianfar: Add Multiple Queue SupportSandeep Gopalpet2009-11-03
| | | | | | | | | | | | | | | This patch introduces multiple Tx and Rx queues. The incoming packets can be classified into different queues based on filer rules (out of scope of this patch). The number of queues enabled will be based on a DTS entries fsl,num_tx_queues and fsl,num_rx_queues. Although we are enabling multiple queues, the interrupt coalescing is on per device level (etsec-1.7 doesn't support multiple rxics and txics).

* gianfar: Introduce logical group support.Sandeep Gopalpet2009-11-03
| | | | | | | | | | | | | | | This patch introduces the group structure. The elements of this structure are the interrupt lines, their corresponding names, the register memory map. The elements for this group are factored out from the gfar_private structure. The introduction of group structure will help in providing support for newer versions of etsec. Currently, the support is present only for single group and single tx/rx queues. Signed-off-by: Sandeep Gopalpet <Sandeep.Kumar@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* gianfar: Add per queue structure supportSandeep Gopalpet2009-11-03
| | | | | | | | | | | | | This patch introduces per tx and per rx queue structures. Earlier the members of these structures were inside the gfar_private structure. Moving forward if we want to support multiple queues, we need to refactor the gfar_private structure so that introduction of multiple queues is easier.

* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
