2012-09-20drm/radeon: block the keypress on ATIF eventsLuca Tettamanti1-1/+6
The AMD ACPI interface may use ACPI_VIDEO_NOTIFY_PROBE to signal SBIOS requests; block the keypress in this case since the user did not actually press the mode switch key. Signed-off-by: Luca Tettamanti <kronos.it@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2012-09-20ACPI video: allow events handlers to veto the keypressLuca Tettamanti1-4/+4
The standard video events may be overloaded for device specific purposes. For example AMD ACPI interface overloads ACPI_VIDEO_NOTIFY_PROBE (0x81) to signal AMD-specific events. In such cases we don't want to send the keypress (KEY_SWITCHVIDEOMODE) to the userspace because the user did not press the mode switch key (the spurious keypress confuses the DE which usually changes the display configuration and messes up a dual-screen setup). This patch gives the handlers the chance to examine the event and block the keypress if the event is device specific. v2: refactor as suggested by Zhang Rui <rui.zhang@intel.com> Signed-off-by: Luca Tettamanti <kronos.it@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2012-09-20Annotate int2float() as being a pure function.Steven Fuerst2-2/+2
This allows gcc to fold duplicate calls into a single call. Since the current users do actually call it multiple times with the same arguments, this is an obvious win. Signed-off-by: Steven Fuerst <svfuerst@gmail.com>
2012-09-20Replace int2float() with an optimized version.Steven Fuerst1-23/+28
We use __fls() to find the most significant bit. Using that, the loop can be avoided. A second trick is to use the behaviour of the rotate instructions to expand the range of the unsigned int to float conversion to the full 32 bits in a branchless way. The routine is now exact up to 2^24. Above that, we truncate which is equivalent to rounding towards zero. Signed-off-by: Steven Fuerst <svfuerst@gmail.com>
2012-09-20Rename i2f() to int2float(), and make it global so one copy can be removed.Steven Fuerst3-79/+40
Remove the copy of i2f() in r600_blit_kms.c We rename the function to something longer now that it is a global symbol. This reduces the likelyhood of unintended clashes later. This might be a candidate for inclusion inside general drm infrastructure. However, at the moment only the radeon driver uses it. Signed-off-by: Steven Fuerst <svfuerst@gmail.com>

2012-09-20drm/radeon: Prevent leak of scratch register on resume from suspendSimon Kitching1-1/+2
Cards typically have 5-7 scratch registers; one of these is reserved for rdev->rptr_save_reg. Unfortunately the reservation is done in function r100_cp_init, which is called by all drivers except r600 - and this function is also invoked on resume from suspend. After several resumes, no scratch registers are free and graphics acceleration is disabled. Dmesg then reports either: *ERROR* radeon: cp failed to get scratch reg (-22). *ERROR* radeon: cp isn't working(-22). radeon 0000:01:00.0: failed initializing CP (-22). or: *ERROR* radeon: failed to get scratch reg (-22). *ERROR* radeon: failed testing IB on GFX ring (-22). *ERROR* ib ring test failed (-22). The chain of calls on boot for all except r600 is: radeon_init -> ... -> (rXXX_init) -> rXXX_startup -> r100_cp_init The chain of calls on resume for all except r600 is: rXXX_resume -> rXXX_startup -> r100_cp_init. R600 correctly allocates rptr_save_reg in r600_init (ie once only, not in resume). However moving the code into the init functions for all drivers means touching 4 drivers. So instead, this patch just adds a test in r100_cp_init to avoid reallocating on resume. As the rdev structure is allocated via kzalloc in radeon_driver_load_kms, and zero is not a valid registerid, zero safely implies not-yet-allocated.

2012-09-14drm/radeon: make 64bit fences more robust v3Christian König1-3/+5
Only increase the higher 32bits if we really detect a wrap around. v2: instead of increasing the higher 32bits just use the higher 32bits from the last emitted fence. v3: also use last emitted fence value as upper limit. The intention of this patch is to make fences as robust as they where before introducing 64bit fences. This is necessary because on older systems it looks like the fence value gets corrupted on initialization. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=51344 Should also fix: https://bugs.freedesktop.org/show_bug.cgi?id=54129 https://bugs.freedesktop.org/show_bug.cgi?id=54662 https://bugzilla.redhat.com/show_bug.cgi?id=846505 https://bugzilla.redhat.com/show_bug.cgi?id=845639 3.5 needs a separate patch due to changes in the fence code.
