Right now, the variables that define the max number of delay frames is defined as: #define VIDEO_FRAME_DELAY 2 #define MAX_NUM_VIDEO_DELAY_FRAMES (VIDEO_FRAME_DELAY + 1) #define NUM_PREVIEW_DVS_FRAMES (2) #define MAX_NUM_DELAY_FRAMES MAX(MAX_NUM_VIDEO_DELAY_FRAMES, NUM_PREVIEW_DVS_FRAMES) In other words, we have: MAX_NUM_VIDEO_DELAY_FRAMES = 3 MAX_NUM_DELAY_FRAMES = 2 The MAX_NUM_DELAY_FRAMES macro is used only only when allocating memory. On all other parts, including looping over such array, MAX_NUM_VIDEO_DELAY_FRAMES is used instead, like: void sh_css_binary_args_reset(struct sh_css_binary_args *args) { unsigned int i; ... for (i = 0; i < MAX_NUM_VIDEO_DELAY_FRAMES; i++) args->delay_frames[i] = NULL; Which will cause buffer overflows, with may override the next array (tnr_frames[]). In practice, this may not be causing real issues, as the code checks for num_delay_frames on some parts (but not everywhere). So, get rid of the smallest value. Acked-by: -

Some arguments for tnf and ref settings are meant to be const, but they're defined without such annotation. Due to that, there's an ugly cast at sh_css_sp.c. Acked-by:

This driver has 3 different types of debug messages: - dev_dbg() - dbg_level - ia_css_debug_trace_level Which is crazy. Ideally, it shold just use dev_dbg() everywhere, but for now let's unify the last two machanisms. Acked-by:

Currently, when an EOF IRQ is received, it generates two messages: [ 59.191893] atomisp-isp2 0000:00:03.0: irq:0x200000 [ 59.191913] atomisp-isp2 0000:00:03.0: atomisp_isr EOF exp_id 142, asd 0 Flooding the dmesg with lots of messages per second. The same pattern happens for all other IRQs. Change the logic for printing just one message per IRQ and rate-limit those, as, for debugging purposes, it is usually interesting to know that IRQs are being received, but not displaying every single one.

The code under load_primary_binaries() is complex and were hard to understand, because it used to have lots of ifdefs and broken identation. The patch which cleaned it and removed the version-specific ifdefs added a regression. Solve it. Fixes: 3c0538fb ("media: atomisp: get rid of most checks for ISP2401 version") Signed-off-by:

The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] sizeof(flexible-array-member) triggers a warning because flexible array members have incomplete type[1]. There are some instances of code in which the sizeof operator is being incorrectly/erroneously applied to zero-length arrays and the result is zero. Such instances may be hiding some bugs. So, this work (flexible-array member conversions) will also help to get completely rid of those sorts of issues. This issue was found with the help of Coccinelle.

Fixes bug exposed by: [a3fbc2e6: media: mc-entity.c: use WARN_ON, validate link pads] The dvbdev incorrectly requests a tuner sink pad to connect to a demux sink pad. The media controller failure percolates back and the dvb device creation fails. Fix this by requesting a tuner source pad. Instead of forcing that pad to be index zero, check if a negative integer error is returned. A note is added that first source pad found is chosen. Affected bridges cx231xx and em28xx printed the below warning[s] when a variety of media controller dvb enabled devices were connected. The warning returns an error causing all affected devices to fail DVB device creation.

When checking sh_css.c against the Yocto Aero's version, it can be noticed that some isp2401 dependencies may have been taken wrongly. Change the code to work like the Yocto Aero, as this driver was tested in the past with an ISP2401 device. Signed-off-by: -

Depending on the ISP-specific HAS_NO_INPUT_FORMATTER macro, some IRQs will be ignored by the driver. Yet, those keep happening, as reported by this debug print: [ 61.620746] atomisp-isp2 0000:00:03.0: atomisp_css_irq_enable: css irq info 0x00000004: disable. Causing this warning: [ 61.620749] atomisp-isp2 0000:00:03.0: atomisp_css_irq_enable:Invalid irq info. Well, if this is a normal situation, just ignore it without warnings. Signed-off-by: -

Calling acpi_bus_get_device() may end allocating resources that aren't freed. So, add a notice about that, as, if those drivers get out of staging, we may need some changes. Fixes: 0d64e942 ("media: atomisp: Add some ACPI detection info") Signed-off-by:

The memory management code for atomisp is complex: it has 2 extra pools (plus some ION-specific code). The code for those extra pools are complex, and there are even some parts of code over there that were forked from some mm/ code, probably from Kernel 3.10. Let's just use a single one, in order to make the driver simpler. Signed-off-by: -

There is an ov2680 driver mainstream. Use the read/write routines from it, as the ones inside this driver are generating some errors: ov2680 i2c-OVTI2680:00: ov2680_i2c_write: i2c write reg=0x3086, value 0x00, error -121 Maybe the code that changes from/to BE are not right. Signed-off-by: -

The sensor should finish its init before atomisp driver, as otherwise the atomisp driver won't be able to talk with it. So, we need to turn atomisp_gmin_platform into a module again, for it to not depend on atomisp driver to finish probing, and add some delay at atomisp to let the sensor driver to finish probing. Yeah, this is hacky. The real solution here would be to use the async framework, but for now, our goal is to make the driver to work. So, let's postpone such change to be done later. Signed-off-by: -

The current code causes ISP2401 to power down and never return back to live, causing the driver to crash. Fix it by commenting out the bad code. It should be noticed that the Yocto Aero code has something similar to it. Maybe the issue is related to an ISP bug (or maybe PM is controlled on a different way for this hardware). Signed-off-by: -
