| * drm/hyperv: Add ratelimit on error messageSaurabh Sengar2022-09-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to a full ring buffer, the driver may be unable to send updates to the Hyper-V host. But outputing the error message can make the problem worse because console output is also typically written to the frame buffer. Rate limiting the error message, also output the error code for additional diagnosability.

| * drm/hyperv: Don't overwrite dirt_needed value set by hostSaurabh Sengar2022-09-231-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Existing code is causing a race condition where dirt_needed value is already set by the host and gets overwritten with default value. Remove this default setting of dirt_needed, to avoid overwriting the value received in the channel callback set by vmbus_open. Removing this setting also means the default value for dirt_needed is changed to false as it's allocated by kzalloc which is similar to legacy hyperv_fb driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There were two different approaches getting used in this driver to allocate vram: 1. VRAM allocation from PCI region for Gen1 2. VRAM alloaction from MMIO region for Gen2 First approach limilts the vram to PCI BAR size, which is 64 MB in most legacy systems. This limits the maximum resolution to be restricted to 64 MB size, and with recent conclusion on fbdev issue its concluded to have similar allocation strategy for both Gen1 and Gen2. This patch unifies the Gen1 and Gen2 vram allocation strategy.

Over time dma-buf-map grew up to more functionality than the one used by dma-buf: in fact it's just a shim layer to abstract system memory, that can be accessed via regular load and store, from IO memory that needs to be acessed via arch helpers. The idea is to extend this API so it can fulfill other needs, internal to a single driver. Example: in the i915 driver it's desired to share the implementation for integrated graphics, which uses mostly system memory, with discrete graphics, which may need to access IO memory. The conversion was mostly done with the following semantic patch: @r1@ @@ - struct dma_buf_map + struct iosys_map @r2@ @@ ( - DMA_BUF_MAP_INIT_VADDR + IOSYS_MAP_INIT_VADDR | - dma_buf_map_set_vaddr + iosys_map_set_vaddr | - dma_buf_map_set_vaddr_iomem + iosys_map_set_vaddr_iomem | - dma_buf_map_is_equal + iosys_map_is_equal | - dma_buf_map_is_null + iosys_map_is_null | - dma_buf_map_is_set + iosys_map_is_set | - dma_buf_map_clear + iosys_map_clear | - dma_buf_map_memcpy_to + iosys_map_memcpy_to | - dma_buf_map_incr + iosys_map_incr ) @@ @@ - #include <linux/dma-buf-map.h> + #include <linux/iosys-map.h> Then some files had their includes adjusted and some comments were update to remove mentions to dma-buf-map.

| * drm/hyperv: Fix device removal on Gen1 VMsMohammed Gamal2021-11-231-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Hyper-V DRM driver tries to free MMIO region on removing the device regardless of VM type, while Gen1 VMs don't use MMIO and hence causing the kernel to crash on a NULL pointer dereference. Fix this by making deallocating MMIO only on Gen2 machines and implement removal for Gen1 Fixes: 76c56a5affeb ("drm/hyperv: Add DRM driver for hyperv synthetic video device") Signed-off-by: Mohammed Gamal <mgamal@redhat.com> Reviewed-by: Deepak Rawat <drawat.floss@gmail.com> Signed-off-by: Deepak Rawat <drawat.floss@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211119112900.300537-1-mgamal@redhat.com

| * drm/hyperv: Fix double mouse pointersDexuan Cui2021-10-153-1/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hyper-V supports a hardware cursor feature. It is not used by Linux VM, but the Hyper-V host still draws a point as an extra mouse pointer, which is unwanted, especially when Xorg is running. The hyperv_fb driver uses synthvid_send_ptr() to hide the unwanted pointer. When the hyperv_drm driver was developed, the function synthvid_send_ptr() was not copied from the hyperv_fb driver. Fix the issue by adding the function into hyperv_drm.
