v2: use the new exported interface. This code was poking inside a struct and assuming it was a drm_mm at the start. Call the proper API. Reviewed-by:

As suggested on review, just export the memory type debug for drivers to use, while also making the debug callback optional (don't need to test for system as it won't init it). rename it to be more consistent with object name for now. (we may rename all the objects later.) Reviewed-by:

clang static analysis reports this repesentative error pvr2fb.c:1049:2: warning: 1st function call argument is an uninitialized value [core.CallAndMessage] if (*cable_arg) ^~~~~~~~~~~~~~~ Problem is that cable_arg depends on the input loop to set the cable_arg[0]. If it does not, then some random value from the stack is used. A similar problem exists for output_arg. So initialize cable_arg and output_arg. Signed-off-by:Tom Rix <trix@redhat.com> Acked-by:

The hdmi4.c and hdmi5.c files include the legacy GPIO header <linux/gpio.h> but does not use any of the symbols from this file.

This patch adds support for G200 desktop cards. We can reuse the whole memory and modesetting code. A few PCI and DAC register values have to be updated accordingly. The most significant change is in the PLL setup. The driver parses the device's BIOS to retrieve clock limits and reference clocks. With no BIOS found, safe defaults are being used. v2: * copy BIOS ROM to system memory and access with regular load/store; resolves potential HW limitations * fix some stray whitespaces Signed-off-by:

MGA cards can run in traditional VGA mode or an enhanced MGA mode; with the latter being required for KMS. So far, MGA mode was enabled during modesetting. As it's fundamental for device operation, the patch moves it next to the device register setup. Signed-off-by:

Thomas Zimmermann authored
So far, PCI option registers were initialized as part of modesetting, which is late in the process. As these registers control fundamental operation, they should be set early. The patch moves the PCI option handling into device register setup, before even the device MMIO memory is being mapped. No functional changes made. Moving the PCI code next to the device-register setup also allows to remove the has_sdram field from struct mga_device. The state is now local to the init helper. Signed-off-by:

The mgag200 driver maps registers into the address space. Move the code into a separate helper function. No functional changes. One small difference is in the handling of SDRAM/SGRAM. MGA devices can come with either SDRAM or SGRAM. So far, the driver checked for SDRAM, which is the common case. The patch moves this code into a separate helper and checks for SGRAM, which is the special case. The test itself is the same as before. Signed-off-by:

SHMEM pages use write-combine caching by default, but can also use the platform's default page caching. Doing so may improve the performance of I/O on the framebuffer. Mgag200's hardware does not access framebuffer pages directly (i.e., via DMA), so enabling caching does not have an effect on consistency of the framebuffer memory or the displayed data.

This turns the ast's device cleanup code into a managed release helper function. Note that the code uses devres helpers. The release function switches the device back to VGA mode and therefore runs during HW device cleanup; not at DRM device cleanup. Signed-off-by:

Turns struct ast_private into a subclass of struct drm_device by embedding the latter. This allows for using DRM's managed device allocation. The use of struct drm_device.dev_private is deprecated. The patch converts the last remaining users to to_ast_private(). Signed-off-by:

Several places in ast use ast->dev, when a dev pointer is already available within the function. Remove the extra indirection. No functional changes made. This is just a small cleanup before embedding the DRM device instance in struct ast_private. Signed-off-by:

The ast driver's load and unload functions are left-overs from when struct drm_driver.load/unload was still in use. The PCI probe helper allocated the DRM device and ran load to initialize it. This patch replaces this code with device create and destroy. The main difference is that the device's create function allocates the DRM device and ast structures in the same place. This will be required for switching ast to managed allocations. Signed-off-by:

Putting the DRM driver to the top of the file and the PCI code to the bottom makes ast_drv.c more readable. While at it, the patch prefixes file-scope variables with ast_. Signed-off-by:

Userspace can provoke this, we generally don't allow userspace to spam dmesg. Tune it down to debug. Unfortunately we don't have easy access to the drm_device here (not at all without changing a few things), so leave it as old style dmesg output for now.
