2010-10-15llseek: automatically add .llseek fopArnd Bergmann2-1/+5
All file_operations should get a .llseek operation so we can make nonseekable_open the default for future file operations without a .llseek pointer. The three cases that we can automatically detect are no_llseek, seq_lseek and default_llseek. For cases where we can we can automatically prove that the file offset is always ignored, we use noop_llseek, which maintains the current behavior of not returning an error from a seek. New drivers should normally not use noop_llseek but instead use no_llseek and call nonseekable_open at open time. Existing drivers can be converted to do the same when the maintainer knows for certain that no user code relies on calling seek on the device file. The generated code is often incorrectly indented and right now contains comments that clarify for each added line why a specific variant was chosen. In the version that gets submitted upstream, the comments will be gone and I will manually fix the indentation, because there does not seem to be a way to do that using coccinelle. Some amount of new code is currently sitting in linux-next that should get the same modifications, which I will do at the end of the merge window. Many thanks to Julia Lawall for helping me learn to write a semantic patch that does all this. ===== begin semantic patch ===== // This adds an llseek= method to all file operations, // as a preparation for making no_llseek the default. // // The rules are // - use no_llseek explicitly if we do nonseekable_open // - use seq_lseek for sequential files // - use default_llseek if we know we access f_pos // - use noop_llseek if we know we don't access f_pos, // but we still want to allow users to call lseek // @ open1 exists @ identifier nested_open; @@ nested_open(...) { <+... nonseekable_open(...) ...+> } @ open exists@ identifier open_f; identifier i, f; identifier open1.nested_open; @@ int open_f(struct inode *i, struct file *f) { <+...

2010-10-11wl1251: move to it's own directoryKalle Valo28-10268/+0
wl1271 driver is under heavy development but on the other hand the older wl1251 driver is currently considered more as a legacy driver. To make it easier to develop wl1271 features move wl1251 to it's own directory, drivers/net/wireless/wl1251. There are no functional changes, only moving of files. One regression is that Kconfig won't be updated automatically and user needs to enable wl1251 manually with an older config file. Signed-off-by: Kalle Valo <kvalo@adurom.com> Signed-off-by: John W.

2010-10-05wl1271: Move work-init calls to hw allocationJuuso Oikarinen1-5/+4
Due to legacy reason, dating back to when the wl1251 and wl1271 still were a unified driver, some work-structures are initialized on hardware startup. The hardware recovery code creates a scenario in which it is possible for a workstruct to be re-initialized while the work-function itself is running, which causes a kernel WARNing and a subsequent reboot. To remedy this, move the work initialization calls to the hw allocation, which is the logically correct place for them anyway.

2010-09-28wl1271: Optimize scan durationJuuso Oikarinen4-9/+60
Currently then dwell times for each channel in scans is set to an overly long value, and excessive number of probe-requests are transmitted on each channel (for active scans.) Based on testing, comparable results can be received with smaller dwell-time, and, with fever probe-requests - in fact, reducing the number of probe-requests to 2 seems to increase the number of found results. Configure more optimal values for per channel dwell times. Comparison for the different scan configurations (in my current office environment): dwell-time 60000 3x probe-req == ~60 results 40000 3x probe-req == ~50 results 30000 3x probe-req == ~40 results dwell-time 60000 2x probe-req == ~70 results 40000 2x probe-req == ~60 results 30000 2x probe-req == ~58 results The above are results for a cumulative 3 scan run.

2010-09-28wl1271: Fix scan race conditionJuuso Oikarinen2-3/+2
In the scan state machine, the wl1271_mutex is unlocked first then relocked, and then the scan state variables are modified. This makes it possible for ieee80211_scan_complete to be called twice in some scenarios, as the scan completion event from the firmware may be processed while the mutex is unlocked. To fix the issue, move the ieee80211_scan_complete call last in the function. This is generally safer, but there still may be issues is functions calling the scan state machine rely on states checked before the unlocking of the global mutex. (forward ported from 2.6.32 -- this is not strictly needed anymore, because the mutex doesn't need to be unlocked anymore, but I'm applying this change anyway, so that the call to ieee80211_scan_complete is in the same place) Signed-off-by: Juuso Oikarinen <juuso.oikarinen@nokia.com> Reviewed-by: Saravanan Dhanabal <ext-saravanan.dhanabal@nokia.com> Signed-off-by: Luciano Coelho <luciano.coelho@nokia.com>

2010-09-28wl1271: Implement CMD_SET_STA_STATE to indicate connection completion to FWJuuso Oikarinen2-0/+38
Implement the command function to send CMD_SET_STA_STATE to the firmware. This is used to indicate that association (and the related EAP negotiation) are complete. This is used to tune WLAN-BT coexistense priority towards BT, improving BT A2DP and SCO performance.

2010-09-28wl1271: remove deprecated ACX definitionLuciano Coelho1-1/+0
As of Rev. 6.1.0.0.335, the ACX_SET_SMART_REFLEX_DEBUG command is deprecated. This patch removes it from the wl1271 driver (it wasn't used anyway). Signed-off-by: Luciano Coelho <luciano.coelho@nokia.com> Reviewed-by: Saravanan Dhanabal <ext-saravanan.dhanabal@nokia.com>
2010-09-27wl1271: Fix overflow in wl1271_boot_upload_nvsIdo Yariv1-11/+6
Due to miscalculation of nvs_len, excessive data was sent to the firmware. Fix this by first setting nvs_ptr to point to the first NVS table, and computing the total size of all NVS tables accordingly.

2010-09-21wl1271: make ref_clock configurable by boardOhad Ben-Cohen5-5/+11
The wl1271 device is using a reference clock that may change between board to board. Make the ref_clock parameter configurable by board settings instead of having a hard coded value in the sources.

2010-09-21wl12xx: add platform data passing supportOhad Ben-Cohen2-1/+32
Add a simple mechanism to pass platform data to the SDIO instances of wl12xx. This way there is no confusion over who owns the 'embedded data', typechecking is preserved, and no possibility for the wrong driver to pick up the data. Originally proposed by Russell King.
