* | i2400m: drop i2400m_schedule_work()Tejun Heo2010-12-124-96/+21
|/ | | | | | | | | | | | | | | | | | i2400m implements dynamic work allocation and queueing mechanism in i2400_schedule_work(); however, this is only used for reset and recovery which can be served equally well with preallocated per device works. Replace i2400m_schedule_work() with two work structs in struct i2400m. These works are explicitly canceled when the device is released making calls to flush_scheduled_work(), which is being deprecated, unnecessary. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: "David S.

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) { <+...

| * wimax/i2400m: fix bad race condition check in RX pathInaky Perez-Gonzalez2010-05-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The i2400m->rx_roq data structure is protected against race conditions with a reference count (i2400m->rx_roq_refcount); the pointer can be read-referenced under the i2400m->rx_lock spinlock. The code in i2400m_rx_edata() wasn't properly following access protocol, performing an invalid check on i2400m->rx_roq (which is cleared to NULL when the refcount drops to zero). As such, it was missing to detect when the data structure is no longer valid and oopsing with a NULL pointer dereference. This commit fixes said check by verifying, under the rx_lock spinlock, that i2400m->rx_roq is non-NULL and then increasing the reference count before dropping the spinlock.

The module param : idle_mode_disabled and power_save_disabled are moved from driver.c to control.c. Also these module parameters are declared to be static as they are not required to be global anymore. The module param : rx_reorder_disabled is moved from driver.c file to rx.c file. Also this parameter is declated as static as it is not required to be global anymore. Signed-off-by: Prasanna S Panchamukhi<prasannax.s.panchamukhi@intel.com>

| * | wimax/i2400m: Reset the TX FIFO indices when allocating the TX FIFO in ↵Cindy H Kao2010-05-111-8/+21

When a device reset happens and the TX FIFO is released/re-allocated, a new block of memory may be allocated for the TX FIFO, therefore tx_msg should be cleared so that no any TX threads (tx_worker, tx) would access to the out-of-date addresses. Also, the TX threads use tx_in and tx_out to decide where to put the new host-to-device messages and from where to copy them to the device HW FIFO, these indices have to be cleared so after the TX FIFO is re-allocated during the reset, the indices both refer to the head of the FIFO, ie. a new start. The same rational applies to tx_msg_size and tx_sequence. To protect the indices from being accessed by multiple threads simultaneously, the lock tx_lock has to be obtained before the initializations and released afterwards.

| * | wimax/i2400m: add the error recovery mechanism on TX pathCindy H Kao2010-05-113-0/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds an error recovery mechanism on TX path. The intention is to bring back the device to some known state whenever TX sees -110 (-ETIMEOUT) on copying the data to the HW FIFO. The TX failure could mean a device bus stuck or function stuck, so the current error recovery implementation is to trigger a bus reset and expect this can bring back the device. Since the TX work is done in a thread context, there may be a queue of TX works already that all hit the -ETIMEOUT error condition because the device has somewhat stuck already. We don't want any consecutive bus resets simply because multiple TX works in the queue all hit the same device erratum, the flag "error_recovery" is introduced to denote if we are ready for taking any error recovery.

| * | wimax/i2400m: fix for missed reset events if triggered by dev_reset_handle()Cindy H Kao2010-05-112-16/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem is only seen on SDIO interface since on USB, a bus reset would really re-probe the driver, but on SDIO interface, a bus reset will not re-enumerate the SDIO bus, so no driver re-probe is happening. Therefore, on SDIO interface, the reset event should be still detected and handled by dev_reset_handle(). Problem description: Whenever a reboot barker is received during operational mode (i2400m->boot_mode == 0), dev_reset_handle() is invoked to handle that function reset event. dev_reset_handle() then sets the flag i2400m->boot_mode to 1 indicating the device is back to bootmode before proceeding to dev_stop() and dev_start(). If dev_start() returns failure, a bus reset is triggered by dev_reset_handle(). The flag i2400m->boot_mode then remains 1 when the second reboot barker arrives. However the interrupt service routine i2400ms_rx() instead of invoking dev_reset_handle() to handle that reset event, it filters out that boot event to bootmode because it sees the flag i2400m->boot_mode equal to 1. The fix: Maintain the flag i2400m->boot_mode within dev_reset_handle() and set the flag i2400m->boot_mode to 1 when entering dev_reset_handle(). It remains 1 until the dev_reset_handle() issues a bus reset. ie: the bus reset is taking place just like it happens for the first time during operational mode. To denote the actual device state and the state we expect, a flag i2400m->alive is introduced in addition to the existing flag i2400m->updown. It's maintained with the same way for i2400m->updown but instead of reflecting the actual state like i2400m->updown does, i2400m->alive maintains the state we expect. i2400m->alive is set 1 just like whenever i2400m->updown is set 1. Yet i2400m->alive remains 1 since we expect the device to be up all the time until the driver is removed. See the doc for @alive in i2400m.h. An enumeration I2400M_BUS_RESET_RETRIES is added to define the maximum number of bus resets that a device reboot can retry. A counter i2400m->bus_reset_retries is added to track how many bus resets have been retried in one device reboot. If I2400M_BUS_RESET_RETRIES bus resets were retried in this boot, we give up any further retrying so the device would enter low power state. The counter i2400m->bus_reset_retries is incremented whenever dev_reset_handle() is issuing a bus reset and is cleared to 0 when dev_start() is successfully done, ie: a successful reboot.
