Make sure that batman-adv does not process packets before its initialization is complete. Some sanity checks added to the receiver function. Signed-off-by:

The vis code takes a copy of the data inside the skbuf if it is interesting for us, so we always need to release the skbuf. Reported-by:

This fixes the bug discovered by Marek Lindner which did not allow turning on the vis-server before an interface has been added. With this patch we are using a global atomic variable for activating and deactiating the vis-server-mode, which can be used before inserting an interface. Signed-off-by:

This patch removes a variable that became obsolete since the skb handling replaced the packet handling thread. Signed-off-by:

The routing code has 2 sections which warn about ttl exceeded. The corresponding warnings were identical which makes it hard to debug. In addition, batman-adv does not need to warn about ttl exceeded in case we encountered an echo request as this is commonly used to generate traceroute graphs. Signed-off-by:

As in other parts of batman-adv, we should not lock while sending a packet but keep the lock held for as short as possible. Additionally, we should check whether the interface is active, otherwise batman_if->net_dev might not be available ... Signed-off-by:

The code which uses the raw packet sockets was removed. The only related dependencies are the skb and netdev handling code. This is provided by NET in Kconfig. Signed-off-by:

VMIVME-7805 board has a special control register that has to be used in order to activate the VME bus access via the Universe II bridge. This control register also handles endianess convertion. Signed-off-by:

For VME device I/O operations on master windows the user driver tends to use kern_buf buffer array which is not allocated. This causes an error when reading from master window device files. Signed-off-by:
-
Arthur Benilov authored
When requesting slave resources A16 addressing mode flag is used to find available windows. Since the ca91cx42 bridge only supports two A16 slave windows but four are requested, the driver fails to initialize. The flag has been changed to A24, which is supported by all slave windows. Signed-off-by:

Specify Kconfig dependencies, and include warnings for building as a module udlfb is dependent on FB_DEFERRED_IO, FB_SYS_*, and FB_MODE_HELPERS Because many kernels do not include defio (which cannot be built as a module), yet users want to be able to build udlfb as a module later, udlfb has ifdefs and these dependency warnings to help udlfb build with or without certain dependencies, but also print warnings for any lost function. Even though this kind of flexibility isn't common, we've gotten feedback from a significant portion of users that they were frustrated without it. Signed-off-by:

Add support for fbdev mmap clients who don't send damage ioctls Because DisplayLink devices are out on the other end of usb, their "framebuffer" is just normal system memory. So memory mapped writes don't automatically trigger anything. So up to this point, standard fbdev clients who rely on mmap() will get an unchanging screen. This patch makes udlfb a client of Jaya Kumar's defio framework - which sets up page fault triggers, and those faults are accumulated and sent to udlfb on a defferred basis, to process as damage notifications for the framebuffer. Because this involves more overhead than a notification directly from the application (e.g. just passing on X DAMAGE extension notifications), a sysfs attribute is provided by udlfb to control defio support. /sys/class/graphics/fb*/use_defio - writing a "0" to this file before calling mmap() causes defio to not be initialized - instead udlfb will rely on getting damage notifications directly through the damage ioctl. There are unsolved rendering problems with defio (horizontal dead regions on framebuffer, that accumulate over time) which still needs a fix. Signed-off-by:

Rework rendering for improved performance Approx 10-20% gain avg across several "benchmarks": x11perf, gtkperf, glxgears Moves from a single pre-alloc'd urb protected by a long-held mutex To a list of (4) pre-alloc'd urbs which can be dispatched asynchonously Improved rendering algorithm to hardware with lower CPU consumption, fewer system memory accesses, and slightly higher compression. Better scalability to multiple processors, especially with multiple framebuffers active. Signed-off-by:

Rework probe to use refcounts and std functions Because the different parts of the driver (usb, fbdev) tear down in different orders, the driver previously could crash accessing data that had already been freed. Refcounting system used to handle. Reworked probe to make use of refcounts, set mode using std fbops, and set up sysfs and pre-allocated urbs. Signed-off-by:

Add sysfs controls for edid and performance metrics There are 8 new files exposed in /sys/class/graphics/fb* edid - returns 128 byte edid blog, suitable for parsing with parse-edid metrics_bytes_identical metrics_bytes_rendered metrics_bytes_sent metrics_cpu_kcycles_used metrics_misc and metrics_reset, which resets all perf metrics to zero The 6 perf metrics are of type atomic_t. So these metrics return precise results for short benchmarks, but any test approx a minute or longer runtime may roll over. Signed-off-by:

Add functions to pre-allocate and free usb bulk urbs for core render path. Udlfb currently allocates a single urb, guarded by a mutex, that is a key bottleneck. Because udlfb sends so much data, preallocation is most efficient. Functions will be used by new rendering functions in later patches. Signed-off-by:
