2023-11-03drm/amdgpu: don't use ATRM for external devicesAlex Deucher1-0/+5
The ATRM ACPI method is for fetching the dGPU vbios rom image on laptops and all-in-one systems. It should not be used for external add in cards. If the dGPU is thunderbolt connected, don't try ATRM. v2: pci_is_thunderbolt_attached only works for Intel. Use pdev->external_facing instead. v3: dev_is_removable() seems to be what we want Link: https://gitlab.freedesktop.org/drm/amd/-/issues/2925 Reviewed-by: Mario Limonciello <[email protected]> Signed-off-by: Alex Deucher <[email protected]> Cc: [email protected]

2022-11-29drm/amdgpu: Fix PCI device refcount leak in amdgpu_atrm_get_bios()Xiongfeng Wang1-0/+1
As comment of pci_get_class() says, it returns a pci_device with its refcount increased and decreased the refcount for the input parameter @from if it is not NULL. If we break the loop in amdgpu_atrm_get_bios() with 'pdev' not NULL, we need to call pci_dev_put() to decrease the refcount. Add the missing pci_dev_put() to avoid refcount leak.

2020-03-30PCI: Use ioremap(), not phys_to_virt() for platform ROMMikel Rychliski1-13/+18
On some EFI systems, the video BIOS is provided by the EFI firmware. The boot stub code stores the physical address of the ROM image in pdev->rom. Currently we attempt to access this pointer using phys_to_virt(), which doesn't work with CONFIG_HIGHMEM. On these systems, attempting to load the radeon module on a x86_32 kernel can result in the following: BUG: unable to handle page fault for address: 3e8ed03c #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page *pde = 00000000 Oops: 0000 [#1] PREEMPT SMP CPU: 0 PID: 317 Comm: systemd-udevd Not tainted 5.6.0-rc3-next-20200228 #2 Hardware name: Apple Computer, Inc.

Instead of calling the helper function pci_platform_rom() which uses phys_to_virt(), call ioremap() directly on the pdev->rom. radeon_read_platform_bios() previously directly accessed an __iomem pointer. Avoid this by calling memcpy_fromio() instead of kmemdup(). pci_platform_rom() now has no remaining callers, so remove it.

2016-12-21ACPI / osl: Remove acpi_get_table_with_size()/early_acpi_os_unmap_memory() usersLv Zheng1-1/+2
This patch removes the users of the deprectated APIs: acpi_get_table_with_size() early_acpi_os_unmap_memory() The following APIs should be used instead of: acpi_get_table() acpi_put_table() The deprecated APIs are invented to be a replacement of acpi_get_table() during the early stage so that the early mapped pointer will not be stored in ACPICA core and thus the late stage acpi_get_table() won't return a wrong pointer. The mapping size is returned just because it is required by early_acpi_os_unmap_memory() to unmap the pointer during early stage. But as the mapping size equals to the acpi_table_header.length (see acpi_tb_init_table_descriptor() and acpi_tb_validate_table()), when such a convenient result is returned, driver code will start to use it instead of accessing acpi_table_header to obtain the length. Thus this patch cleans up the drivers by replacing returned table size with acpi_table_header.length, and should be a no-op.
