ramoops: Move to fs/pstore/ram.c

2012-05-16T15:06:37Z

Since ramoops was converted to pstore, it has nothing to do with character devices nowadays. Instead, today it is just a RAM backend for pstore. The patch just moves things around. There are a few changes were needed because of the move: 1. Kconfig and Makefiles fixups, of course. 2. In pstore/ram.c we have to play a bit with MODULE_PARAM_PREFIX, this is needed to keep user experience the same as with ramoops driver (i.e. so that ramoops.foo kernel command line arguments would still work).

tty: delete briq_panel.c driver

This driver is broken, as reported by Jiri, and to quote Ben: Just remove the driver, I don't think anybody cares. so I'm doing just that here. Reported-by: Jiri Slaby Cc: Alan Cox Cc: Josh Boyer Cc: Benjamin Herrenschmidt Signed-off-by: Greg Kroah-Hartman

arch/tile: add hypervisor-based character driver for SPI flash ROM

2011-06-10T17:07:48Z

The first version of this patch proposed an arch/tile/drivers/ directory, but the consensus was that this was probably a poor choice for a place to group Tilera-specific drivers, and that in any case grouping by platform was discouraged, and grouping by function was preferred. This version of the patch addresses various issues raised in the community, primarily the absence of sysfs integration. The sysfs integration now handles passing information on sector size, page size, and total partition size to userspace as well. In addition, we now use a single "struct cdev" to manage all the partition minor devices, and dynamically discover the correct number of partitions from the hypervisor rather than using a module_param with a default value. This driver has no particular "peer" drivers it can be grouped with. It is sort of like an MTD driver for SPI ROM, but it doesn't group well with the other MTD devices since it relies on hypervisor virtualization to handle many of the irritating aspects of flash ROM management: sector awareness, background read for sub-sector writes, bit examination to determine whether a sector erase needs to be issued, etc. It is in fact more like an EEPROM driver, but the hypervisor virtualization does require a "flush" command if you wish to commit a sector write prior to writing to a different sector, and this is sufficiently different from generic I2C/SPI EEPROMs that as a result it doesn't group well with them either. The simple character device is already in use by a range of Tilera SPI ROM management tools, as well as by customers. In addition, using the simple character device actually simplifies the userspace tools, since they don't need to manage sector erase, background read, etc. This both simplifies the code (since we can uniformly manage plain files and the SPI ROM) as well as makes the user code portable to non-Linux platforms that don't offer the same MTD ioctls.

As planned by Arnd Bergmann, this moves the following drivers to the drivers/staging/generic_serial directory where they will be removed after 2.6.41 if no one steps up to claim them. generic_serial rio ser_a2232 sx vme_scc Cc: Arnd Bergmann Cc: Alan Cox Cc: Jiri Slaby Signed-off-by: Greg Kroah-Hartman

virtio: console: Move file back to drivers/char/

2011-02-03T22:43:12Z

Commit 728674a7e466628df2aeec6d11a2ae1ef968fb67 moved virtio_console.c to drivers/tty/hvc/ under the perception of this being an hvc driver. It was such once, but these days it has generic communication capabilities as well, so move it to drivers/char/. In the future, the hvc part from this file can be split off and moved under drivers/tty/hvc/. Signed-off-by: Amit Shah CC: Rusty Russell Acked-by: Arnd Bergmann Signed-off-by: Greg Kroah-Hartman

tty: move hvc drivers to drivers/tty/hvc/

2011-01-13T20:03:00Z

As requested by Arnd Bergmann, the hvc drivers are now moved to the drivers/tty/hvc/ directory. The virtio_console.c driver was also moved, as it required the hvc_console.h file to be able to be built, and it really is a hvc driver. Cc: Arnd Bergmann Signed-off-by: Greg Kroah-Hartman
