| * mm: replace get_vaddr_frames() write/force parameters with gup_flagsLorenzo Stoakes2016-10-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | This removes the 'write' and 'force' from get_vaddr_frames() and replaces them with 'gup_flags' to make the use of FOLL_FORCE explicit in callers as use of this flag can result in surprising behaviour (and hence bugs) within the mm subsystem.

* | [media] omap: don't break long linesMauro Carvalho Chehab2016-10-212-13/+16
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to the 80-cols restrictions, and latter due to checkpatch warnings, several strings were broken into multiple lines. This is not considered a good practice anymore, as it makes harder to grep for strings at the source code. As we're right now fixing other drivers due to KERN_CONT, we need to be able to identify what printk strings don't end with a "\n". It is a way easier to detect those if we don't break long lines. So, join those continuation lines. The patch was generated via the script below, and manually adjusted if needed. </script> use Text::Tabs; while (<>) { if ($next ne "") { $c=$_; if ($c =~ /^\s+\"(.*)/) { $c2=$1; $next =~ s/\"\n$//; $n = expand($next); $funpos = index($n, '('); $pos = index($c2, '",'); if ($funpos && $pos > 0) { $s1 = substr $c2, 0, $pos + 2; $s2 = ' ' x ($funpos + 1) . substr $c2, $pos + 2; $s2 =~ s/^\s+//; $s2 = ' ' x ($funpos + 1) . $s2 if ($s2 ne ""); print unexpand("$next$s1\n"); print unexpand("$s2\n") if ($s2 ne ""); } else { print "$next$c2\n"; } $next=""; next; } else { print $next; } $next=""; } else { if (m/\"$/) { if (!m/\\n\"$/) { $next=$_; next; } } } print $_; } </script> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

* [media] v4l: Support extending the v4l2_pix_format structureLaurent Pinchart2014-07-171-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | The v4l2_pix_format structure has no reserved field. It is embedded in the v4l2_framebuffer structure which has no reserved fields either, and in the v4l2_format structure which has reserved fields that were not previously required to be zeroed out by applications. To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer structure, and use the priv field as a magic value to indicate that the application has set all v4l2_pix_format extended fields and zeroed all reserved fields following the v4l2_pix_format field in the v4l2_format structure. The availability of this API extension is reported to userspace through the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the priv field is still set to the magic value at [GS]_FMT return wouldn't be enough, as older kernels don't zero the priv field on return. To simplify the internal API towards drivers zero the extended fields and set the priv field to the magic value for applications not aware of the extensions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When booting with DT, there's a crash when omapfb is probed. This is caused by the fact that omapdss+DT is not yet supported, and thus omapdss is not probed at all. On the other hand, omapfb is always probed. When omapfb tries to use omapdss, there's a NULL pointer dereference crash. The same error should most likely happen with omapdrm and omap_vout also. To fix this, add an "initialized" state to omapdss. When omapdss has been probed, it's marked as initialized. omapfb, omapdrm and omap_vout check this state when they are probed to see that omapdss is actually there.

* | [media] Corrected Oops on omap_vout when no manager is connectedFederico Fuga2013-03-211-4/+10
|/ | | | | | | | | | | | | | If no manager is connected to the vout device, the omapvid_init() function fails. No error condition is checked, and the device is started. Later on, when irq is serviced, a NULL pointer dereference occurs. Also, the isr routine must be registered only if no error occurs, otherwise the isr triggers without the proper setup, and the kernel oops again. To prevent this, the error condition is checked, and the streamon function exits with error. Also the isr registration call is moved after the setup procedure is completed.

* [media] omap_vout: find_vma() needs ->mmap_sem heldAl Viro2013-01-061-5/+7
| | | | | | | | | | | | | | | | | | | | | | | Walking rbtree while it's modified is a Bad Idea(tm); besides, the result of find_vma() can be freed just as it's getting returned to caller. Fortunately, it's easy to fix - just take ->mmap_sem a bit earlier (and don't bother with find_vma() at all if virtp >= PAGE_OFFSET - in that case we don't even look at its result). While we are at it, what prevents VIDIOC_PREPARE_BUF calling v4l_prepare_buf() -> (e.g) vb2_ioctl_prepare_buf() -> vb2_prepare_buf() -> __buf_prepare() -> __qbuf_userptr() -> vb2_vmalloc_get_userptr() -> find_vma(), AFAICS without having taken ->mmap_sem anywhere in process? The code flow is bloody convoluted and depends on a bunch of things done by initialization, so I certainly might've missed something...

To remove the dependency to OMAP platform code this patch changes omap_vout to use the omapdss version. For most of the checks, the ones dealing with DSS differences, this is actually more correct than using cpu_is_* functions. For the check whether VRFB is available or not this is not really correct, but still works fine.

Unfortunately that was before I was able to try to test compile of the ARM multiplatform builds for omap2+, and the end result was not very good. So I'm creating yet another all over the place patch to cut the last dependency for building omap2+ for ARM multiplatform. After this, we have finally removed the driver dependencies to the arch/arm code, except for few drivers that are being worked on. The other option was to make the <plat-omap/dma-omap.h> path to work, but we'd have to add some new header directory to for multiplatform builds. Or we would have to manually include arch/arm/plat-omap/include again from arch/arm/Makefile for omap2+. Neither of these alternatives sound appealing as they will likely lead addition of various other headers exposed to the drivers, which we want to avoid for the multiplatform kernels. Since we already have a minimal include/linux/omap-dma.h, let's just use that instead and add a note to it to not use the custom omap DMA functions any longer where possible. Note that converting omap DMA to dmaengine depends on dmaengine supporting automatically incrementing the FIFO address at the device end, and converting all the remaining legacy drivers. So it's going to be few more merge windows.

They don't need to be called as the omap_vout_device struct anyway maintains the overlay related changes made. Also, remove the explicit call to set_overlay_info() in vidioc_streamon(), this was used to set the paddr, this isn't needed as omapvid_init() does the same thing later. These changes are required as the DSS2 driver since 3.3 kernel doesn't let you set the overlay info with paddr as 0.
