Essentially the entire software stack is reset, together with the relevant hardware, so users don't have to reset the entire phone. - STE Modem driver is added - by Sjur Brændeland - OMAP DSP boot address support is added - by Juan Gutierrez - A handful of fixes/cleanups - Sjur Brændeland, Dan Carpenter, Emil Goode * tag 'remoteproc-for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/ohad/remoteproc: remoteproc: Fix use of format specifyer remoteproc: fix a potential NULL-dereference on cleanup remoteproc: select VIRTIO to avoid build breakage remoteproc: return -EFAULT on copy_from_user failure remoteproc: snprintf() can return more than was printed remoteproc: Add STE modem driver remtoteproc: maintain max notifyid remoteproc: create a 'recovery' debugfs entry remoteproc: add actual recovery implementation remoteproc: add rproc_report_crash function to notify rproc crashes remoteproc: Add dependency to HAS_DMA remoteproc/omap: set bootaddr support

| * remoteproc: snprintf() can return more than was printedDan Carpenter2012-09-301-2/+2
| | | | | | | | | | | | | | | | | | | | | | snprintf() returns the number of characters which would have been printed if there were enough space. For example, on the first print if we fill up the 28 character string then it would return a number more than 30. Use scnprintf() instead because that returns the actual number of characters printed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the STE modem shared memory driver. This driver hooks into the remoteproc framework in order to manage configuration and the virtio devices. This driver adds custom firmware handlers, because STE modem uses a custom firmware layout.

| * remoteproc: create a 'recovery' debugfs entryFernando Guzman Lugo2012-09-183-1/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a 'recovery' debugfs entry to dynamically disable/enable recovery at runtime. This is useful when one is trying to debug an rproc crash; without it, a recovery will immediately take place, making it harder to debug the crash. Contributions from Subramaniam Chanderashekarapuram. Examples: - disabling recovery: $ echo disabled > <debugfs>/remoteproc/remoteproc0/recovery - in case you want to recover a crash, but keep recovery disabled (useful in debugging sessions when you expect additional crashes you want to debug): $ echo recover > <debugfs>/remoteproc/remoteproc0/recovery - enabling recovery: $ echo enabled > <debugfs>/remoteproc/remoteproc0/recovery Signed-off-by: Fernando Guzman Lugo <fernando.lugo@ti.com> [ohad: some white space, commentary and commit log changes] Signed-off-by: Ohad Ben-Cohen <ohad@wizery.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | Add rproc_trigger_recovery() which takes care of the recovery itself, by removing, and re-adding, all of the remoteproc's virtio devices. This resets all virtio users of the remote processor, during which the remote processor is powered off and on again.

| * remoteproc: add rproc_report_crash function to notify rproc crashesFernando Guzman Lugo2012-09-183-4/+100
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow low-level remoteproc drivers to report rproc crashes by exporting a new rproc_report_crash() function (invoking this from non-rproc drivers is probably wrong, and should be carefully scrutinized if ever needed). rproc_report_crash() can be called from any context; it offloads the tasks of handling the crash to a separate thread. Handling the crash from a separate thread is helpful because: - Ability to call invoke rproc_report_crash() from atomic context, due to the fact that many crashes trigger an interrupt, so this function can be called directly from ISR context. - Avoiding deadlocks which could happen if rproc_report_crash() is called from a function which indirectly holds the rproc lock. Handling the crash might involve: - Remoteproc register dump - Remoteproc stack dump - Remoteproc core dump - Saving Remoteproc traces so they can be read after the crash - Reseting the remoteproc in order to make it functional again (hard recovery) Right now, we only print the crash type which was detected, and only the mmufault type is supported. Remoteproc low-level drivers can add more types when needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some remote processors (like OMAP4's DSP) require we explicitly set a boot address from which they'd start executing code when taken out of reset. Support for this is now being added to the omap-specific remoteproc driver through a set_bootaddr function in the platform data which, if needed, must be set according to the backend remote processor. For OMAP4's dsp we can use the following control function: .set_bootaddr = omap_ctrl_write_dsp_boot_addr Signed-off-by: Juan Gutierrez <jgutierrez@ti.com> Signed-off-by: Suman Anna <s-anna@ti.com> [ohad: slight changes to the commit log] Signed-off-by: Ohad Ben-Cohen <ohad@wizery.com>

In short, current eagerfpu changes return 0 for interrupted_kernel_fpu_idle() and the in_interrupt() thinks it is in the interrupt context because of the local_bh_disable(). Thus resulting in the WARN_ON(). Remove the local_bh_disable/enable() calls around the existing local_irq_disable/enable() calls. local_irq_disable/enable() already disables the BH. [ If there are any other legitimate users calling kernel_fpu_begin() from the process context but with BH disabled, then we can look into fixing the irq_fpu_usable() in future. ] Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> Cc: Tim Chen <tim.c.chen@linux.intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
