From 2fa6d6cdaf283c05ae23842b2a04aeb223203c13 Mon Sep 17 00:00:00 2001 From: Sinan Kaya Date: Tue, 19 Dec 2017 00:37:45 -0500 Subject: drm/nouveau: deprecate pci_get_bus_and_slot() pci_get_bus_and_slot() is restrictive such that it assumes domain=0 as where a PCI device is present. This restricts the device drivers to be reused for other domain numbers. Getting ready to remove pci_get_bus_and_slot() function in favor of pci_get_domain_bus_and_slot(). Replace pci_get_bus_and_slot() with pci_get_domain_bus_and_slot() and extract the domain number from 1. struct pci_dev 2. struct pci_dev through drm_device->pdev 3. struct pci_dev through fb->subdev->drm_device->pdev Signed-off-by: Sinan Kaya Signed-off-by: Bjorn Helgaas --- drivers/gpu/drm/nouveau/dispnv04/arb.c | 4 +++- drivers/gpu/drm/nouveau/dispnv04/hw.c | 10 +++++++--- drivers/gpu/drm/nouveau/nouveau_drm.c | 3 ++- drivers/gpu/drm/nouveau/nvkm/subdev/fb/ramnv1a.c | 10 +++++++++- 4 files changed, 21 insertions(+), 6 deletions(-) (limited to 'drivers') diff --git a/drivers/gpu/drm/nouveau/dispnv04/arb.c b/drivers/gpu/drm/nouveau/dispnv04/arb.c index 90075b676256..c79160c37f84 100644 --- a/drivers/gpu/drm/nouveau/dispnv04/arb.c +++ b/drivers/gpu/drm/nouveau/dispnv04/arb.c @@ -213,8 +213,10 @@ nv04_update_arb(struct drm_device *dev, int VClk, int bpp, if ((dev->pdev->device & 0xffff) == 0x01a0 /*CHIPSET_NFORCE*/ || (dev->pdev->device & 0xffff) == 0x01f0 /*CHIPSET_NFORCE2*/) { uint32_t type; + int domain = pci_domain_nr(dev->pdev->bus); - pci_read_config_dword(pci_get_bus_and_slot(0, 1), 0x7c, &type); + pci_read_config_dword(pci_get_domain_bus_and_slot(domain, 0, 1), + 0x7c, &type); sim_data.memory_type = (type >> 12) & 1; sim_data.memory_width = 64; diff --git a/drivers/gpu/drm/nouveau/dispnv04/hw.c b/drivers/gpu/drm/nouveau/dispnv04/hw.c index b98599002831..0c9bdf023f5b 100644 --- a/drivers/gpu/drm/nouveau/dispnv04/hw.c +++ b/drivers/gpu/drm/nouveau/dispnv04/hw.c @@ -216,12 +216,15 @@ nouveau_hw_get_clock(struct drm_device *dev, enum nvbios_pll_type plltype) { struct nvkm_pll_vals pllvals; int ret; + int domain; + + domain = pci_domain_nr(dev->pdev->bus); if (plltype == PLL_MEMORY && (dev->pdev->device & 0x0ff0) == CHIPSET_NFORCE) { uint32_t mpllP; - - pci_read_config_dword(pci_get_bus_and_slot(0, 3), 0x6c, &mpllP); + pci_read_config_dword(pci_get_domain_bus_and_slot(domain, 0, 3), + 0x6c, &mpllP); mpllP = (mpllP >> 8) & 0xf; if (!mpllP) mpllP = 4; @@ -232,7 +235,8 @@ nouveau_hw_get_clock(struct drm_device *dev, enum nvbios_pll_type plltype) (dev->pdev->device & 0xff0) == CHIPSET_NFORCE2) { uint32_t clock; - pci_read_config_dword(pci_get_bus_and_slot(0, 5), 0x4c, &clock); + pci_read_config_dword(pci_get_domain_bus_and_slot(domain, 0, 5), + 0x4c, &clock); return clock / 1000; } diff --git a/drivers/gpu/drm/nouveau/nouveau_drm.c b/drivers/gpu/drm/nouveau/nouveau_drm.c index 8d4a5be3b913..33b6139c1bf1 100644 --- a/drivers/gpu/drm/nouveau/nouveau_drm.c +++ b/drivers/gpu/drm/nouveau/nouveau_drm.c @@ -524,7 +524,8 @@ nouveau_get_hdmi_dev(struct nouveau_drm *drm) } /* subfunction one is a hdmi audio device? */ - drm->hdmi_device = pci_get_bus_and_slot((unsigned int)pdev->bus->number, + drm->hdmi_device = pci_get_domain_bus_and_slot(pci_domain_nr(pdev->bus), + (unsigned int)pdev->bus->number, PCI_DEVFN(PCI_SLOT(pdev->devfn), 1)); if (!drm->hdmi_device) { diff --git a/drivers/gpu/drm/nouveau/nvkm/subdev/fb/ramnv1a.c b/drivers/gpu/drm/nouveau/nvkm/subdev/fb/ramnv1a.c index 4c07d10bb976..18241c6ba5fa 100644 --- a/drivers/gpu/drm/nouveau/nvkm/subdev/fb/ramnv1a.c +++ b/drivers/gpu/drm/nouveau/nvkm/subdev/fb/ramnv1a.c @@ -28,8 +28,16 @@ nv1a_ram_new(struct nvkm_fb *fb, struct nvkm_ram **pram) { struct pci_dev *bridge; u32 mem, mib; + int domain = 0; + struct pci_dev *pdev = NULL; - bridge = pci_get_bus_and_slot(0, PCI_DEVFN(0, 1)); + if (dev_is_pci(fb->subdev.device->dev)) + pdev = to_pci_dev(fb->subdev.device->dev); + + if (pdev) + domain = pci_domain_nr(pdev->bus); + + bridge = pci_get_domain_bus_and_slot(domain, 0, PCI_DEVFN(0, 1)); if (!bridge) { nvkm_error(&fb->subdev, "no bridge device\n"); return -ENODEV; -- cgit v1.2.3
