version 2:
- simplify function prototype to only keep device as parameter
- rebased on v4.10
Lots of calls to of_platform_populate() are not unbalanced by a call
to of_platform_depopulate(). This create issues while drivers are
bind/unbind.
In way to solve those issues is to add devm_of_platform_populate()
which will call of_platform_depopulate() when the device is unbound
from the bus. This also could make drivers more robust in case that
probe failed after calling of_platform_populate().
Benjamin Gaignard (2):
of: add devm_ functions for populate and depopulate
drm: sti: make driver use devm_of_platform_populate()

version 2:
- rebase code on 4.10-rc7
- fix bug in CMA allocator
- do more tests with wayland dmabuf protocol:
https://git.linaro.org/people/benjamin.gaignard/simple_allocator.git
The goal of this RFC is to understand if a common ioctl for specific memory
regions allocations is needed/welcome.
Obviously it will not replace allocation done in linux kernel frameworks like
v4l2, drm/kms or others, but offer an alternative when you don't want/need to
use them for buffer allocation.
To keep a compatibility with what already exist allocated buffers are exported
in userland as dmabuf file descriptor (like ION is doing).
"Unix Device Memory Allocator" project [1] wants to create a userland library
which may allow to select, depending of the devices constraint, the best
back-end for allocation. With this RFC I would to propose to have common ioctl
for a maximum of allocators to avoid to duplicated back-ends for this library.
One of the issues that lead me to propose this RFC it is that since the beginning
it is a problem to allocate contiguous memory (CMA) without using v4l2 or
drm/kms so the first allocator available in this RFC use CMA memory.
An other question is: do we have others memory regions that could be interested
by this new framework ? I have in mind that some title memory regions could use
it or replace ION heaps (system, carveout, etc...).
Maybe it only solve CMA allocation issue, in this case there is no need to create
a new framework but only a dedicated ioctl.
Maybe the first thing to do is to change the name and the location of this
module, suggestions are welcome.
I have testing this code with the following program:
#include <errno.h>
#include <fcntl.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <sys/ioctl.h>
#include <sys/mman.h>
#include <sys/stat.h>
#include <sys/types.h>
#include "simple-allocator.h"
#define LENGTH 1024*16
void main (void)
{
struct simple_allocate_data data;
int fd = open("/dev/cma0", O_RDWR, 0);
int ret;
void *mem;
if (fd < 0) {
printf("Can't open /dev/cma0\n");
return;
}
memset(&data, 0, sizeof(data));
data.length = LENGTH;
data.flags = O_RDWR | O_CLOEXEC;
ret = ioctl(fd, SA_IOC_ALLOC, &data);
if (ret) {
printf("Buffer allocation failed\n");
goto end;
}
mem = mmap(0, LENGTH, PROT_READ | PROT_WRITE, MAP_SHARED, data.fd, 0);
if (mem == MAP_FAILED) {
printf("mmap failed\n");
}
memset(mem, 0xFF, LENGTH);
munmap(mem, LENGTH);
printf("test simple allocator CMA OK\n");
end:
close(fd);
}
