drm/hyperv: Add ratelimit on error message

2022-09-29T16:28:28Z

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 host

2022-09-23T10:11:20Z

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 are already three places in kernel which define PCI_VENDOR_ID_MICROSOFT and two for PCI_DEVICE_ID_HYPERV_VIDEO and there's a need to use these from core VMBus code. Move the defines where they belong. No functional change.

drm/hyperv : Removing the restruction of VRAM allocation with PCI bar size

2022-05-30T22:25:36Z

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.
