The improvements are mainly about better supporting varios virtio properties (such as virtio's config space, status and features). I now see that I messed up while commiting one of Sjur's patches and erroneously put myself as the author, as well as letting a nasty typo sneak in. I will not fix this in order to avoid rebasing the patches. Sjur - sorry! - A new remoteproc driver for OMAP-L13x (technically a DaVinci platform) from Robert Tivy. - Extend OMAP support to OMAP5 as well, from Vincent Stehlé. - Fix Kconfig VIRTUALIZATION dependency, from Suman Anna (a non-critical fix which arrived late during the rc cycle). * tag 'remoteproc-3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/ohad/remoteproc: remoteproc: fix kconfig dependencies for VIRTIO remoteproc/davinci: add a remoteproc driver for OMAP-L13x DSP remoteproc: support default firmware name in rproc_alloc() remoteproc/omap: support OMAP5 too remoteproc: set vring addresses in resource table remoteproc: support virtio config space. remoteproc: perserve resource table data remoteproc: calculate max_notifyid by counting vrings remoteproc: code cleanup of resource parsing remoteproc: parse STE-firmware and find resource table address remoteproc: add find_loaded_rsc_table firmware ops remoteproc: refactor rproc_elf_find_rsc_table()

| * | 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.

| * | remoteproc: Add STE modem driverSjur Brændeland2012-09-223-0/+334
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some of the rproc drivers (STE modem specifically) needs to know the range of the notification IDs used for notifying the device. Maintain a variable in struct rproc holding the largest allocated notification id, so low-level rproc drivers could access it.

| * | remoteproc: create a 'recovery' debugfs entryFernando Guzman Lugo2012-09-182-1/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

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 Lugo2012-09-181-4/+75

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>

| * remoteproc: Support custom firmware handlersSjur Brændeland2012-07-153-16/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Firmware handling is made customizable. This is done by creating a separate ops structure for the firmware functions that depends on a particular firmware format (such as ELF). The ELF functions are default used unless the HW driver explicitly injects another firmware handler by updating rproc->fw_ops. The function rproc_da_to_va() is exported, as custom firmware handlers may need to use this function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prepare for introduction of custom firmware loaders by moving all ELF related handling into a separate file. The functions: rproc_find_rsc_table(), rproc_fw_sanity_check(), rproc_find_rsc_table() and rproc_get_boot_addr() are moved to the new file remoteproc_elf_loader.c. The function rproc_da_to_va() is made non-static and is declared in remoteproc_internal.h No functional changes are introduced in this patch.
