When hotpluging hdmi the read of edid often fails.
Add up to 4 retries with a 500ms delay before giving up.
|
|
Initialisation of the framebuffer console on DVI-D aka HDMI always
failed on monitors which report the vertical front porch to be 1
in their EDID.
The fix now changes also the modedb and not only the list of
videomodes with a compatible timing.
This was particularly bad on Apalis T30 where this is activated
by default. On Colibri T30 this was observed when enabling it using the
fbcon=map:1 boot argument.

Hack to avoid 24 Hz mode in X resulting in no display at all. This has
been encountered using e.g. a Samsung SyncMaster F2380 if connected by
HDMI.

This patch allows for easy integration of a custom Linux boot logo to
replace the Tux' being shown by default.
Use gimp or the like to create a raw PPM in your desired resolution.
Reduce the number of colours in the image to 224:
user@host:~$ ppmquant 224 Toradex-640x480.ppm > \
Toradex-640x480-224.ppm
ppmquant: making histogram...
ppmquant: 370 colors found
ppmquant: choosing 224 colors...
ppmquant: mapping image to new colors...
Convert it from raw PPM to ASCII format:
user@host:~$ pnmnoraw Toradex-640x480-224.ppm > \
Toradex-640x480-ascii-224.ppm
Copy it into the Linux sources:
cp Toradex-640x480-ascii-224.ppm linux-toradex/drivers/video/logo/\
logo_custom_clut224.ppm
Activate exclusively custom Linux logo in the kernel configuration:
Device Drivers -> Graphics support -> Bootup logo ->
Custom 224-color Linux logo
And re-compile the kernel.

A handle's usecount used to be incremented once during the mmap ioctl,
and decremented when the mapping is closed by the kernel. However, that
fails if a mapping cloned, for example if the mapping was split due to
a munmap, or (presumably) during fork, as the decrement will then happen
for each cloned mapping.
Therefore increment the usecount when a mapping is opened.
Also fix a BUG_ON() that would have caught this bug, if it wouldn't
have done the check by checking if the unsigned usecount field is
less than zero.

nvhost_3dctx_alloc_common correctly checks the return value of an
allocator function, and attempts to perform cleanup. However, this
particular allocation API returns ERR_PTR values in case of failure,
which then gets passed to the deallocation function, causing a crash.
Also, the return value of that allocator API is checked with IS_ERR
in some places, and with IS_ERR_OR_NULL in others. For consistency
and avoiding surprises if the allocation implementation changes,
use IS_ERR_OR_NULL in all places.

nvhost_module_remove_client assumes that a client structure
to be freed exists in the linked list. However, if an allocation fails
in nvhost_module_add_client, no client structure is allocated, and
during cleanup, nvhost_module_remove_client would then attempt
to free an invalid pointer.

do_heap_alloc locates a suitable free block from a nvmap heap given a
size and alignment. Unfortunately, if a heap block happens to be
smaller than the alignment passed to the function, an integer overflow
will occur, and a block that's too small gets accidentally returned.

nvmap_map_into_caller_ptr takes a memory handle from usermode
and adds a memory mapping for the handle. However, the handle
is not checked for being allocated. An unallocated handle
would cause a kernel panic later on from a NULL dereference.

When 3D register is read, and we need to do a context switch, the old
context reference is incremented, but it never gets decremented. Fix
by using nvhost_job_get_hwctx() to acquire the reference.
