Leave the common code in radeon_encoders.c and move the atom specific code to atombios_encoders.c. This matches legacy encoder setup and crtc setup. Signed-off-by:

The vram scratch was originally only used on some 7xx asics to work around a hw bug. Allocate the scratch page on all 6xx+ radeons and set the MC_VM_SYSTEM_APERTURE_DEFAULT_ADDR to point to it. We shouldn't ever hit it since we limit the system aperture to vram or vram and AGP, but better safe than sorry. Signed-off-by:

radeon_driver_irq_preinstall_kms and radeon_driver_irq_uninstall_kms hard code the loop to 6 which happens to be the current maximum number of crtcs and hpd pins; if one day an ASIC with more crtcs (or hpd pins) comes out, this is a trouble waiting to happen. introduce constants for maximum CRTC count, maximum HPD pins count and maximum HDMI blocks count (per FIXME in radeon_irq structure) and correct the loops in radeon_driver_irq_preinstall_kms and radeon_driver_irq_uninstall_kms v2: take care of goofs pointed out by Alex Deucher Signed-off-by:

Cayman seems to be particularly sensitive to read cache returning old data after bind/unbind to GTT. Flush read cache for GTT range with each fences for all new hw. Should fix several rendering glitches.

Since force handling rework of d0d0a225 we could end up bouncing connector status btw disconnected and unknown. When connector status change a call to output_poll_changed happen which in turn ask again for detect but with force set. So set the load detect flags whenever we report the connector as connected or unknown this avoid bouncing btw disconnected and unknown. Signed-off-by:

epoll can acquire recursively acquire ep->mtx on multiple "struct eventpoll"s at once in the case where one epoll fd is monitoring another epoll fd. This is perfectly OK, since we're careful about the lock ordering, but it causes spurious lockdep warnings. Annotate the recursion using mutex_lock_nested, and add a comment explaining the nesting rules for good measure. Recent versions of systemd are triggering this, and it can also be demonstrated with the following trivial test program: --------------------8<-------------------- int main(void) { int e1, e2; struct epoll_event evt = { .events = EPOLLIN }; e1 = epoll_create1(0); e2 = epoll_create1(0); epoll_ctl(e1, EPOLL_CTL_ADD, e2, &evt); return 0; } --------------------8<-------------------- Reported-by:Paul Bolle <pebolle@tiscali.nl> Tested-by:

Some find using utf-8 in commit logs inappropriate. Some patch commit logs contain unintended utf-8 characters when doing things like copy/pasting compilation output. Look for the start of any commit log by skipping initial lines that look like email headers and "From: " lines. Stop looking for utf-8 at the first signature line. Signed-off-by:

Commit 84c95c9a ("string: on strstrip(), first remove leading spaces before running over str") improved the performance of the strim() function. Unfortunately this changed the semantics of strim() and broke my code. Before the patch it was possible to use strim() without using the return value for removing trailing spaces from strings that had either only blanks or only trailing blanks. Now this does not work any longer for strings that *only* have blanks. Before patch: " " -> "" (empty string) After patch: " " -> " " (no change) I think we should remove your patch to restore the old behavior. The description (lib/string.c): * Note that the first trailing whitespace is replaced with a %NUL-terminator => The first trailing whitespace of a string that only has whitespace characters is the first whitespace The patch restores the old strim() semantics.

__bitmap_parse() and __bitmap_parselist() both take a pointer to a kernel buffer as a parameter and then cast it to a pointer to user buffer for use in cases when the parameter is_user indicates that the buffer is actually located in user space. This casting, and the casts in the callers, results in sparse noise like the following: warning: incorrect type in initializer (different address spaces) expected char const [noderef] <asn:1>*ubuf got char const *buf warning: cast removes address space of expression Since these casts are intentional, use __force to quiet the noise.

When SPIN_BUG_ON is triggered, the lock owner information is reported. But it is omitted when spinlock lockup is detected. This information is useful especially on the architectures which don't implement trigger_all_cpu_backtrace() that is called just after detecting lockup. So report it and also avoid message format duplication. Signed-off-by:

Currently termination logic (\0 or \n\0) is hardcoded in _kstrtoull(), avoid that for code reuse between kstrto*() and simple_strtoull(). Essentially, make them different only in termination logic. simple_strtoull() (and scanf(), BTW) ignores integer overflow, that's a bug we currently don't have guts to fix, making KSTRTOX_OVERFLOW hack necessary. Almost forgot: patch shrinks code size by about ~80 bytes on x86_64. Signed-off-by:

Depending on the implementation of the hardware blinking function in blink_set(), the led can support hardware blinking for some values of delay_on and delay_off and fall-back to software blinking for some other values. Turning off the blink_timer unconditionally before starting to blink make sure that a sequence like: OFF hardware blinking software blinking hardware blinking does not leave the software blinking timer active.

When calling the hardware blinking function implemented by blink_set(), the delay_on and delay_off values are not preserved across calls. Fix that and make the "timer" trigger work as expected when hardware blinking is available.

We can change gpio_get_value() to gpio_get_value_cansleep() because it is only called from the platform_driver probe function, which is a context where we can sleep.
