drm/i915/gvt: Introduce a framework for tracking HW registers. This patch introduces a framework for tracking HW registers on different GEN platforms. Accesses to GEN HW registers from VMs will be trapped by hypervisor. It will forward these emulation requests to GVT-g device model, which requires this framework to search for related register descriptions. Each MMIO entry in this framework describes a GEN HW registers, e.g. offset, length, whether it contains RO bits, whether it can be accessed by LRIs...and also emulation handlers for emulating register reading and writing. - Use i915 MMIO register definition & statement.(Joonas) Signed-off-by: Zhi Wang <zhi.a.wang@intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com>

drm/i915/gvt: clean up intel_gvt.h as interface for i915 core i915 core should only call functions and structures exposed through intel_gvt.h. Remove internal gvt.h and i915_pvinfo.h. Change for internal intel_gvt structure as private handler which not requires to expose gvt internal structure for i915 core. v2: Fix per Chris's comment - carefully handle dev_priv->gvt assignment - add necessary bracket for macro helper - forward declartion struct intel_gvt - keep free operation within same file handling alloc v3: fix use after free and remove intel_gvt.initialized v4: change to_gvt() to an inline Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com>

drm/i915/gvt: verify functions types in new_mmio_info() The current prototype of new_mmio_info() uses void* for parameters read and write, which are functions with precise calling conventions (argument types and return type). Write down these conventions in new_mmio_info() definition. This has been reported by the following warnings when clang is used to build the kernel: drivers/gpu/drm/i915/gvt/handlers.c:124:21: error: pointer type mismatch ('void *' and 'int (*)(struct intel_vgpu *, unsigned int, void *, unsigned int)') [-Werror,-Wpointer-type-mismatch] info->read = read ? read : intel_vgpu_default_mmio_read; ^ ~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/gpu/drm/i915/gvt/handlers.c:125:23: error: pointer type mismatch ('void *' and 'int (*)(struct intel_vgpu *, unsigned int, void *, unsigned int)') [-Werror,-Wpointer-type-mismatch] info->write = write ? write : intel_vgpu_default_mmio_write; ^ ~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This allows the compiler to detect that sbi_ctl_mmio_write() returns a "bool" value instead of an expected "int" one.

drm/i915/gvt: verify functions types in new_mmio_info() The current prototype of new_mmio_info() uses void* for parameters read and write, which are functions with precise calling conventions (argument types and return type). Write down these conventions in new_mmio_info() definition. This has been reported by the following warnings when clang is used to build the kernel: drivers/gpu/drm/i915/gvt/handlers.c:124:21: error: pointer type mismatch ('void *' and 'int (*)(struct intel_vgpu *, unsigned int, void *, unsigned int)') [-Werror,-Wpointer-type-mismatch] info->read = read ? read : intel_vgpu_default_mmio_read; ^ ~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/gpu/drm/i915/gvt/handlers.c:125:23: error: pointer type mismatch ('void *' and 'int (*)(struct intel_vgpu *, unsigned int, void *, unsigned int)') [-Werror,-Wpointer-type-mismatch] info->write = write ? write : intel_vgpu_default_mmio_write; ^ ~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This allows the compiler to detect that sbi_ctl_mmio_write() returns a "bool" value instead of an expected "int" one.

drm/i915/gvt: Fix superfluous newline in GVT_DISPLAY_READY env var send_display_send_uevent() sends two environment variable, and the first one GVT_DISPLAY_READY is set including a new line at the end of the string; that is obviously superfluous and wrong -- at least, it *looks* so when you only read the code. However, it doesn't appear in the actual output by a (supposedly unexpected) trick. The code uses snprintf() and truncates the string in size 20 bytes. This makes the string as GVT_DISPLAY_READY=0 or ...=1 including the trailing NUL-letter. That is, the '\n' found in the format string is always cut off as a result. Although the code gives the correct result, it is confusing. This patch addresses it, just removing the superfluous '\n' from the format string for avoiding further confusion. If the argument "ready" were not a bool, the size 20 should be corrected as well. But it's a bool, so we can leave the magic number 20 as is for now. FWIW, the bug was spotted by a new GCC7 warning: drivers/gpu/drm/i915/gvt/handlers.c: In function 'pvinfo_mmio_write': drivers/gpu/drm/i915/gvt/handlers.c:1042:34: error: 'snprintf' output truncated before the last format character [-Werror=format-truncation=] snprintf(display_ready_str, 20, "GVT_DISPLAY_READY=%d\n", ready); ^~~~~~~~~~~~~~~~~~~~~~~~ drivers/gpu/drm/i915/gvt/handlers.c:1042:2: note: 'snprintf' output 21 bytes into a destination of size 20 snprintf(display_ready_str, 20, "GVT_DISPLAY_READY=%d\n", ready); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Fixes: 04d348ae3f0a ("drm/i915/gvt: vGPU display virtualization") Bugzilla: https://bugzilla.suse.com/show_bug.cgi?id=1025903 Reported-by: Richard Biener <rguenther@suse.com> Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com>

drm/i915/gvt: Introduce a framework for tracking HW registers. This patch introduces a framework for tracking HW registers on different GEN platforms. Accesses to GEN HW registers from VMs will be trapped by hypervisor. It will forward these emulation requests to GVT-g device model, which requires this framework to search for related register descriptions. Each MMIO entry in this framework describes a GEN HW registers, e.g. offset, length, whether it contains RO bits, whether it can be accessed by LRIs...and also emulation handlers for emulating register reading and writing. - Use i915 MMIO register definition & statement.(Joonas) Signed-off-by: Zhi Wang <zhi.a.wang@intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com>

drm/i915/gvt: Introduce a framework for tracking HW registers. This patch introduces a framework for tracking HW registers on different GEN platforms. Accesses to GEN HW registers from VMs will be trapped by hypervisor. It will forward these emulation requests to GVT-g device model, which requires this framework to search for related register descriptions. Each MMIO entry in this framework describes a GEN HW registers, e.g. offset, length, whether it contains RO bits, whether it can be accessed by LRIs...and also emulation handlers for emulating register reading and writing. - Use i915 MMIO register definition & statement.(Joonas) Signed-off-by: Zhi Wang <zhi.a.wang@intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com>

drm/i915/gvt: Introduce a framework for tracking HW registers. This patch introduces a framework for tracking HW registers on different GEN platforms. Accesses to GEN HW registers from VMs will be trapped by hypervisor. It will forward these emulation requests to GVT-g device model, which requires this framework to search for related register descriptions. Each MMIO entry in this framework describes a GEN HW registers, e.g. offset, length, whether it contains RO bits, whether it can be accessed by LRIs...and also emulation handlers for emulating register reading and writing. - Use i915 MMIO register definition & statement.(Joonas) Signed-off-by: Zhi Wang <zhi.a.wang@intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com>

drm/i915/gvt: vGPU MMIO virtualization This patch introduces the generic vGPU MMIO emulation intercept framework. The MPT modules will request GVT-g core logic to emulate MMIO read/write through IO emulation operations callback when hypervisor trapped a guest GTTMMIO read/write.

drm/i915/gvt: vGPU display virtualization This patch introduces the GVT-g display virtualization. It consists a collection of display MMIO handlers, like power well register handler, pipe register handler, plane register handler, which will emulate all display MMIOs behavior to support virtual mode setting sequence for guest.

drm/i915/gvt: Introduce a framework for tracking HW registers. This patch introduces a framework for tracking HW registers on different GEN platforms. Accesses to GEN HW registers from VMs will be trapped by hypervisor. It will forward these emulation requests to GVT-g device model, which requires this framework to search for related register descriptions. Each MMIO entry in this framework describes a GEN HW registers, e.g. offset, length, whether it contains RO bits, whether it can be accessed by LRIs...and also emulation handlers for emulating register reading and writing. - Use i915 MMIO register definition & statement.(Joonas) Signed-off-by: Zhi Wang <zhi.a.wang@intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com>
