* PCI: Remove DEFINE_PCI_DEVICE_TABLE macro useBenoit Taine2014-08-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to meet kernel coding style guidelines. This issue was reported by checkpatch. A simplified version of the semantic patch that makes this change is as follows (http://coccinelle.lip6.fr/): // <smpl> @@ identifier i; declarer name DEFINE_PCI_DEVICE_TABLE; initializer z; @@ - DEFINE_PCI_DEVICE_TABLE(i) + const struct pci_device_id i[] = z; // </smpl> [bhelgaas: add semantic patch] Signed-off-by: Benoit Taine <benoit.taine@lip6.fr> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

* p54pci: don't return zero on failure paths in p54p_probe()Alexey Khoroshilov2013-01-071-2/+5
| | | | | | | | | | | | | | If pci_set_dma_mask() or pci_set_consistent_dma_mask() fails in p54p_probe(), it breaks off initialization, deallocates all resources, but returns zero. Similar issue is if check for returned value of pci_resource_len() fails. The patch implements proper error code propagation. Found by Linux Driver Verification project (linuxtesting.org).

* p54pci: convert driver to use asynchronous firmware loadingLarry Finger2012-08-061-26/+62
| | | | | | | | | | | | | | Drivers that load firmware from their probe routine have problems with the latest versions of udev as they get timeouts while waiting for user space to start. The problem is fixed by using request_firmware_nowait() and delaying the start of mac80211 until the firmware is loaded. To prevent the possibility of the driver being unloaded while the firmware loading callback is still active, a completion queue entry is used.

Quoting from the changelog: This patch does it the same way, except that it also prioritize rx data processing, simply because tx routines *can* wait. This is causing an issue with us referencing already freed memory, because some skb's we transmit, we immediately receive back, such as those for reading the eeprom (*) and getting stats. What can happen because of the moving of the tx processing to after the rx processing is that when the tasklet first runs after doing a special skb tx (such as eeprom) we've already received the answer to it. Then the rx processing ends up calling p54_find_and_unlink_skb to find the matching tx skb for the just received special rx skb and frees the tx skb. Then after the processing of the rx skb answer, and thus freeing the tx skb, we go process the completed tx ring entires, and then dereference the free-ed skb, to see if it should free free-ed by p54p_check_tx_ring()."

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes an old problem, which - under certain circumstances - could cause the device to become unresponsive. most of p54pci's rx-ring management is implemented in just two distinct standalone functions. p54p_check_rx_ring takes care of processing incoming data, while p54p_refill_rx_ring tries to replenish all depleted communication buffers. This has always worked fine on my fast machine, but now I know there is a hidden race... The most likely candidate here is ring_control->device_idx. Quintin Pitts had already analyzed the culprit and posted a patch back in Oct 2009. But sadly, no one's picked up on this. ( https://patchwork.kernel.org/patch/53079/ [2 & 3] ). This patch does the same way, except that it also prioritize rx data processing, simply because tx routines *can* wait.

* / 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.

* p54pci: convert printk(KERN_* to dev_*Christian Lamparter2009-03-161-19/+10
| | | | | | | This patch replaces most printk(KERN_* "") with their by dev_* analogue. Signed-off-by: Christian Lamparter <chunkeey@web.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* p54: unify ieee80211 device registrationChristian Lamparter2009-03-161-5/+2
| | | | | | | | All three drivers (p54pci, p54usb and p54spi) are implementing the same functionality three times. So, why not put it into the shared library?! Signed-off-by: Christian Lamparter <chunkeey@web.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* p54: prevent upload of wrong firmwaresChristian Lamparter2009-01-291-0/+6
| | | | | | | | | | | This patch will prevent anyone to upload a firmware which was not designed for his device. There's still a catch: There is no easy way to detect if a firmware is for PCI or for USB (1st Gen), because they all share the same LM86 identifier.

* p54: remove free_on_tx parameterChristian Lamparter2008-12-191-7/+5
| | | | | | | | | | | | This patch simplifies the tx code a bit and will be necessary for the upcoming stlc45xx<->p54 port. In detail: we no longer have to tell all back-end drivers directly, if we want to free a frame right after it was send to the firmware, or if we do it in the library callback later.

* p54: enforce strict tx_queue limitsChristian Lamparter2008-12-121-7/+0
| | | | | | | | The patch fixes an old FIXME in p54pci.c by moving the "queue full" check into the common library, where we can deal with it properly. Signed-off-by: Christian Lamparter <chunkeey@web.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* p54pci: cache firmware for suspend/resumeChristian Lamparter2008-11-251-20/+22
| | | | | | | | Johannes pointed out that the driver has cache the firmware for suspend/resume cycles. Signed-off-by: Christian Lamparter <chunkeey@web.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* p54: introduce new names for device firmwaresChristian Lamparter2008-11-101-3/+6
| | | | | | | | | | Johannes thought it would have been a good idea to change the firmware names. Note: we still have fallbacks in case our users don't want to "break their running system", but we won't advertise them with MODULE_FIRMWARE.

* p54: integrate parts of lmac_longbow.h and other parts of stlc45xxJohn W. Linville2008-11-011-1/+1
| | | | | | | | | | This patch removes most/all? of the "magic" numbers and unknown structure variables inside the code and replaces them with meaningful prototypes. (Plus a one line warning fix from Larry Finger <Larry.Finger@lwfinger.net>.) Signed-off-by: Christian Lamparter <chunkeey@web.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* p54: fix memory managementChristian Lamparter2008-11-011-10/+13
| | | | | | | | | | We have to be careful if multiple "control frames" are passed in a very short intervals to the device's firmware. As p54_assign_address always put them into same memory location. To guarantee that this won't happen anymore, we have to treat control frames like normal data frames in the devices own memory management.
