This module is only selected by the rt2800pci driver if PCI support is enabled in the kernel, because some parts of the rt2x00pci code depends on PCI support. PCI support is not available on the RT3x5x SoCs because those have no PCI host controller at all. Move the non PCI specific code from rt2x00pci into a separate module. This makes it possible to use that code even if PCI support is disabled. The affected functions are used by all of the rt2x00 PCI drivers so select the new module for those drivers.

2011-04-19rt2x00: Allow dynamic addition of PCI/USB IDs.Gertjan van Wingerde
Both USB and PCI drivers allow a system administrator to dynamically add USB/PCI IDs to the device table that a driver supports via the /sys/bus/{usb,pci,pci_express}/drivers/<driver-name>/new_id files. However, for the rt2x00 drivers using this method currently crashes the system with a NULL pointer failure. This is due to the set-up of rt2x00 where the probe functions require a rt2x00_ops structure in the driver_info field of the probed device. As this field is empty for the dynamically added devices this fails for these devices. Fix this by introducing driver-specific probe wrappers that do nothing but calling the bus-specific probe functions with the rt2x00_ops structure as an argument, rather than depending on the driver_info field.

2011-04-19rt2x00: Decrease association time for USB devicesIvo van Doorn
When powersaving is enabled, assocaition times are very high (for WPA2 networks, the time can easily be around the 3 seconds). This is caused, because the flushing of the queues takes too much time. Without the flushing callback mac80211 assumes a timeout of 100ms while scanning. Limit all flush waiting loops to the same maximum. We can apply this maximum by passing the drop status to the driver, which makes sure the driver performs extra actions during the waiting for the queue to become empty. After these changes, association times fall within the healthy range of ~0.6 seconds with powersaving enabled. The difference between association time between powersaving enabled and disabled is now only ~0.1 second (which can also be due to the measuring method).

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
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.

2009-04-20rt2x00: Don't free register information on suspendIvo van Doorn
After suspend & resume the rt2x00 devices won't wakeup anymore due to a broken register information setup. The most important problem is the release of the EEPROM buffer which is completely cleared and never read again after the suspend.

2008-11-25rt2x00: Cleanup indirect register accessIvo van Doorn
All code which accessed indirect registers was similar in respect to the for-loop, the given timeout, etc. Move it into a seperate function, which for PCI drivers can be moved into rt2x00pci. This allows us to cleanup the cleanup the code further by removing the goto statementsand making the codepath look a bit nicer. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2008-11-21rt2x00: Cleanup TX/RX entry handlingIvo van Doorn
Merge the callback functions init_txentry() and init_rxentry(). This makes life in rt2x00lib a lot simpler and we can cleanup several functions. rt2x00pci contained "fake" FIELD definitions for descriptor words. This is not flexible since it assumes the driver will always have the same field to indicate if a driver is available or not. This should be dependent on the driver, and we should add a callback function for this. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-10-31pci: use pci_ioremap_bar() in drivers/netArjan van de Ven
Use the newly introduced pci_ioremap_bar() function in drivers/net. pci_ioremap_bar() just takes a pci device and a bar number, with the goal of making it really hard to get wrong, while also having a central place to stick sanity checks.

2008-06-26rt2x00: Cleanup symbol exportsIvo van Doorn
With a bit of code moving to rt2x00lib within the TX and RX paths we can now remove a lot of EXPORT_SYMBOL_GPL() statements. This cleans up the interface between rt2x00lib and the drivers and has the additional benefit that rt2x00pci and rt2x00usb are trimmed down in size as well since they have less to do.

2008-06-26rt2x00: Replace statically allocated DMA buffers with mapped skb's.Gertjan van Wingerde
The current PCI drivers require a lot of pre-allocated DMA buffers. Reduce this by using dynamically mapped skb's (using pci_map_single) instead of the pre- allocated DMA buffers that are allocated at device start-up time. At the same time move common RX path code into rt2x00lib from rt2x00pci and rt2x00usb, as the RX paths now are now almost the same.

2008-06-26rt2x00: Convert rt2x00 to use generic DMA-mapping APIGertjan van Wingerde
At the same time clean up the device administration a bit, by storing a pointer to struct device instead of a void pointer that is dependent on the type of device. The normal PCI and USB subsystem provided macros can be used to convert the device pointer to the right type. This makes the rt2x00 driver a bit more type-safe.
