* module_param: make bool parameters really bool (drivers & misc)Rusty Russell2012-01-132-11/+11
| | | | | | | | | | | | module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version.

* | atyfb: Fix bootup hangs on sparc64.David S. Miller2011-01-061-22/+5
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After commit 25edd6946a1d74e5e77813c2324a0908c68bcf9e ("sparc64: Get rid of indirect p1275 PROM call buffer.") we can't pass virtual addresses >4GB to PROM calls. Largely this is never necessary in drivers because we have a copy of the entire PROM device tree in the kernel and a set of of_*() interfaces to access it. Unfortunately there were some lingering prom calls in the atyfb driver, in particular prom_finddevice() was being called with an on-stack address which could be anywhere. This code is actually probing for information we already have, the PROM choosen console output device is stored in of_console_device so all of this nasty code consolidates into a one-line comparison. Next we have some prom_getintdefault() calls which are trivially transformed into the equivalent of_getintprop_default(). Special thanks to Fabio, who figured out exactly where the bootup was hanging. That made this bug trivial to fix. Reported-by: Fabio M.

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-304-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | of: unify phandle name in struct device_nodeGrant Likely2010-01-281-1/+1
|/ | | | | | | | | | | | | | | | | | | | | In struct device_node, the phandle is named 'linux_phandle' for PowerPC and MicroBlaze, and 'node' for SPARC. There is no good reason for the difference, it is just an artifact of the code diverging over a couple of years. This patch renames both to simply .phandle. Note: the .node also existed in PowerPC/MicroBlaze, but the only user seems to be arch/powerpc/platforms/powermac/pfunc_core.c. It doesn't look like the assignment between .linux_phandle and .node is significantly different enough to warrant the separate code paths unless ibm,phandle properties actually appear in Apple device trees. I think it is safe to eliminate the old .node property and use phandle everywhere. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.

* radeonfb: Whack the PCI PM register until it sticksBenjamin Herrenschmidt2009-03-221-0/+24
| | | | | | | | | | | | | | | | | | This fixes a regression introduced when we switched to using the core pci_set_power_state(). The chip seems to need the state to be written over and over again until it sticks, so we do that. Note that the code is a bit blunt, without timeout, etc... but that's pretty much because I put back in there the code exactly as it used to be before the regression. I still add a call to pci_set_power_state() at the end so that ACPI gets called appropriately on x86.

* radeonfb/aty128fb: Disable broken early resume hook for PowerBooksBenjamin Herrenschmidt2009-03-112-2/+18
| | | | | | | | | | | | | | | | | | | | | | | | | radeonfb and aty128fb have a special hook called by the PowerMac platform code very very early on resume from sleep to bring the screen back. This is useful for debugging wakup problems, but unfortunately, this also became a source of problems of its own. The hook is called extremely early, with interrupts still off, and the code path involved with that code nowadays rely on things like taking mutexes, GFP_KERNEL allocations, etc... In addition, the driver now relies on the PCI core to restore the standard config space before calling resume which doesn't happen with this early code path. I'm keeping the code in but commented out along with a fixup call to pci_restore_state(). The reason is that I still want to make it easy to re-enable temporarily to track wake up problems, and it's possible that I can revive it at some stage if we make sleeping things save to call in early resume using a system state. In the meantime, this should fix several reported regressions. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

* radeonfb: Fix resume from D3Cold on some platformsBenjamin Herrenschmidt2009-02-082-67/+20
| | | | | | | | | | | | | | | | For historical reason, this driver used its own saving/restoring of the PCI config space, and used the state of it on resume as an indication as to whether it needed to re-POST the chip or not. This methods breaks with the later core changes since the core will have restored things for us. This patch fixes it by removing that custom code, using standard core methods to save/restore state, and testing for the need to re-POST by comparing the content of a few key PLL registers.

| | | | | | | | | | | | | This fixes aty128fb to properly save the PCI config space -before- it potentially switches the PM state of the chip. This avoids a warning with the new PM core and is the right thing to do anyway. I also replaced the hand-coded switch to D2 with a call to the genericc pci_set_power_state() and removed the code that switches it back to D0 since the generic code is doing that for us nowadays.

This avoids a warning with the new PM core and is the right thing to do anyway. I also slightly cleaned up the code that checks whether we are running on a PowerMac to do a runtime check instead of a compile check only, and replaced a deprecated number with the proper symbolic constant. Finally, I removed the useless switch to D0 from resume since the core does it for us.

* fbdev/atyfb: Fix DSP config on some PowerMacs & PowerBooksRisto Suominen2009-02-021-0/+11
| | | | | | | | | | | | | | | | | | Since the complete re-write in 2.6.10, some PowerMacs (At least PowerMac 5500 and PowerMac G3 Beige rev A) with ATI Mach64 chip have suffered from unstable columns in their framebuffer image. This seems to depend on a value (4) read from PLL_EXT_CNTL register, which leads to incorrect DSP config parameters to be written to the chip. This patch uses a value calculated by aty_init_pll_ct instead, as a starting point. There are questions as to whether this should be extended to other platforms or maybe made dependent on specific chip types, but in the meantime, this has been tested on various powermacs and works for them so let's commit it.

| | | | | | | | | | | | | This new color expansion acceleration for radeonfb appears to trigger problems with X on VT switch and suspend/resume on some machines. It might be a problem in the VT layer or in X, but I haven't quite found it yet, so in the meantime, this disables the acceleration by default, reverting to 2.6.27 state.
