drm/amdgpu: Correctly disable the I2C IP block
On long transfers to the EEPROM device,
i.e. write, it is observed that the driver aborts
the transfer.
The reason for this is that the driver isn't
patient enough--the IC_STATUS register's contents
is 0x27, which is MST_ACTIVITY | TFE | TFNF |
ACTIVITY. That is, while the transmission FIFO is
empty, we, the I2C master device, are still
driving the bus.
Implement the correct procedure to disable
the block, as described in the DesignWare I2C
Databook, section 3.8.3 Disabling DW_apb_i2c on
page 56. Now there are no premature aborts on long
data transfers.

drm/amdgpu: Fix koops when accessing RAS EEPROM
Debugfs RAS EEPROM files are available when
the ASIC supports RAS, and when the debugfs is
enabled, an also when "ras_enable" module
parameter is set to 0. However in this case,
we get a kernel oops when accessing some of
the "ras_..." controls in debugfs. The reason
for this is that struct amdgpu_ras::adev is
unset. This commit sets it, thus enabling access
to those facilities. Note that this facilitates
EEPROM access and not necessarily RAS features or

drm/amdgpu: Optimize EEPROM RAS table I/O
Split functionality between read and write, which
simplifies the code and exposes areas of
optimization and more or less complexity, and take
advantage of that.
Read and write the table in one go; use a separate
stage to decode or encode the data, as opposed to
on the fly, which keeps the I2C bus busy. Use a
single read/write to read/write the table or at
most two if the number of records we're
reading/writing wraps around.
Check the check-sum of a table in EEPROM on init.
Update the checksum at the same time as when
updating the table header signature, when the
threshold was increased on boot.
Take advantage of arithmetic modulo 256, that is,
use a byte!, to greatly simplify checksum
arithmetic.

rename this macro to RAS_MAX_RECORD_COUNT.

amdgpu_ras_eeprom_max_record_count().

"max_eeprom_records_len".

drm/amdgpu: Fixes to the AMDGPU EEPROM driver
* When reading from the EEPROM device, there is no
device limitation on the number of bytes
read--they're simply sequenced out. Thus, read
the whole data requested in one go.
* When writing to the EEPROM device, there is a
256-byte page limit to write to before having to
generate a STOP on the bus, as well as the
address written to mustn't cross over the page
boundary (it actually rolls over). Maximize the
data written to per bus acquisition.
* Return the number of bytes read/written, or -errno.

drm/amdkfd: classify and map mixed svm range pages in GPU
[Why]
svm ranges can have mixed pages from device or system memory.
A good example is, after a prange has been allocated in VRAM and a
copy-on-write is triggered by a fork. This invalidates some pages
inside the prange. Endding up in mixed pages.
[How]
By classifying each page inside a prange, based on its type. Device or
system memory, during dma mapping call. If page corresponds
to VRAM domain, a flag is set to its dma_addr entry for each GPU.
Then, at the GPU page table mapping. All group of contiguous pages within
the same type are mapped with their proper pte flags.
v2:
Instead of using ttm_res to calculate vram pfns in the svm_range. It is now
done by setting the vram real physical address into drm_addr array.
This makes more flexible VRAM management, plus removes the need to have
a BO reference in the svm_range.
v3:
Remove mapping member from svm_range

drm/radeon: Call radeon_suspend_kms() in radeon_pci_shutdown() for Loongson64
On the Loongson64 platform used with Radeon GPU, shutdown or reboot failed
when console=tty is in the boot cmdline.
radeon_suspend_kms() puts the hw in the suspend state, especially set fb
state as FBINFO_STATE_SUSPENDED:
if (fbcon) {
console_lock();
radeon_fbdev_set_suspend(rdev, 1);
console_unlock();
}
Then avoid to do any more fb operations in the related functions:
if (p->state != FBINFO_STATE_RUNNING)
return;
So call radeon_suspend_kms() in radeon_pci_shutdown() for Loongson64 to fix
this issue, it looks like some kind of workaround like powerpc.

drm/amdgpu: Set ttm caching flags during bo allocation
The ttm caching flags (ttm_cached, ttm_write_combined etc) are
used to determine a buffer object's mapping attributes in both
CPU page table and GPU page table (when that buffer is also
accessed by GPU). Currently the ttm caching flags are set in
function amdgpu_ttm_io_mem_reserve which is called during
DRM_AMDGPU_GEM_MMAP ioctl. This has a problem since the GPU
mapping of the buffer object (ioctl DRM_AMDGPU_GEM_VA) can
happen earlier than the mmap time, thus the GPU page table
update code can't pick up the right ttm caching flags to
decide the right GPU page table attributes.
This patch moves the ttm caching flags setting to function
amdgpu_vram_mgr_new - this function is called during the
first step of a buffer object create (eg, DRM_AMDGPU_GEM_CREATE)
so the later both CPU and GPU mapping function calls will
pick up this flag for CPU/GPU page table set up.
