| * | include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | The mwl8k firmware uses indices into the 2.4 GHz band rate table for the receive descriptor channel field even if the packet was received on a 5 GHz channel, while mac80211 expects an index into the 5 GHz band rate table when packets are received on the 5 GHz band, which presents a mismatch as the 5 GHz band rate table lacks the five non-OFDM rates that the 2.4 GHz rate table starts with. To handle this properly, we need to substract 5 from the rate index field if the packet was received on a 5 GHz channel (and was not received at an MCS rate).

| | | | | | | | | | | | Like how TX reclaim is done in a tasklet, move receive processing to tasklet context as well. This can have nice benefits for CPU utilisation and throughput, especially at 3-stream rates.

* mwl8k: keep TX_DONE interrupt masked while transmit reclaim is runningLennert Buytenhek2010-01-121-31/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | By making use of the CLEAR_SEL feature of the mwl8k host interface interrupt controller, we can keep the TX_DONE interrupt source masked while the transmit reclaim tasklet is running (NAPI style) without having to touch the interrupt controller's interrupt mask register when entering or exiting polling mode, and without having to do any more register reads/writes than we do now. When CLEAR_SEL is enabled on the TX_DONE interrupt source, reading the interrupt status register will clear the TX_DONE status bit if it was set, allowing it to be set again if a new TX_DONE event arrives while we are running the TX reclaim tasklet, but such a new event will then not trigger another PCI interrupt until a zero is written to the TX_DONE interrupt status register bit. I.e., if we write a zero to the TX_DONE interrupt source bit in the interrupt status register when the TX reclaim tasklet thinks it's done, a PCI interrupt will be triggered if a new TX_DONE event arrived from the hardware between us deciding that there is no more work to do and re-enabling the TX_DONE interrupt source, thereby avoiding the classic NAPI poll mode exit race that would otherwise occur.

* mwl8k: allow limiting the amount of transmit reclaim doneLennert Buytenhek2010-01-121-9/+13
| | | | | | | | | Add a limit argument to mwl8k_txq_reclaim(), to allow limiting the number of packets that it will reclaim, and make it return the number of packets that it reclaimed. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mwl8k: basic AP interface supportLennert Buytenhek2010-01-121-13/+158
| | | | | | | | Add support for creating AP interfaces, and enabling beaconing. This allows running a basic AP (11b/g mode only for now). Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* mwl8k: implement AP firmware station database maintenanceLennert Buytenhek2010-01-121-17/+117
| | | | | | | | | | STA firmware uses UPDATE_STADB to manipulate the hardware station database, whereas AP firmware uses SET_NEW_STN -- this implements the latter, and hooks it into mwl8k_sta_notify(), to be used if we're running on AP firmware.

* mwl8k: add the AP version of USE_FIXED_RATELennert Buytenhek2010-01-121-0/+41
| | | | | | | | | | As with the STA version, unicast will use auto rate adaptation, but the AP version allows setting the rates to be used for management and multicast transmissions, which can be set based on the BSS basic rate set.

* mwl8k: simplify mwl8k_cmd_use_fixed_rate()Lennert Buytenhek2010-01-121-66/+22
| | | | | | | | | As we always use the auto rate adaptation feature and never pass in a rate table, USE_FIXED_RATE can be simplified somewhat. While we're at it, rename it to *_sta, as this is the STA version of the command. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mwl8k: bump the transmit wait timeout to 5 secondsLennert Buytenhek2010-01-121-1/+1
| | | | | | | | | | | | | | While it is reasonable to expect that at least one transmit ring entry will be processed per second while we are waiting for the transmit rings to drain, the firmware can end up doing batching of transmit ring status writeback, which means that the transmit rings can appear stuck for more than a second at a time. Bump the TX drain wait timeout up from 1 to 5 seconds to account for this. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mwl8k: undo transmit queue 0/1 swapping in mwl8k_cmd_set_edca_params()Lennert Buytenhek2010-01-121-6/+0
| | | | | | | | | | The comment and code in mwl8k_cmd_set_edca_params() suggest that the mapping between SET_EDCA_PARAMS queue numbers and transmit rings isn't actually 1:1, while tests show that the mapping is in fact 1:1. So, get rid of the transmit queue 0/1 swapping. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
