* [PATCH v4 13/18] PCI: dwc: Add start_link/stop_link inliners [not found] <20220610082535.12802-1-Sergey.Semin@baikalelectronics.ru> @ 2022-06-10 8:25 ` Serge Semin 2022-06-13 20:39 ` Rob Herring 2022-06-10 8:25 ` [PATCH v4 15/18] PCI: dwc: Add dw_ prefix to the pcie_port structure name Serge Semin 1 sibling, 1 reply; 6+ messages in thread From: Serge Semin @ 2022-06-10 8:25 UTC (permalink / raw) To: Rob Herring, Bjorn Helgaas, Lorenzo Pieralisi, Minghuan Lian, Mingkai Hu, Roy Zang, Krzysztof Wilczyński, Jingoo Han, Gustavo Pimentel Cc: linux-pci, Frank Li, linux-kernel, Serge Semin, Alexey Malahov, Serge Semin, Pavel Parkhomenko, Manivannan Sadhasivam, linuxppc-dev, linux-arm-kernel There are several places in the generic DW PCIe code where the platform-specific PCIe link start/stop methods are called after making sure the ops handler and the callbacks are specified. Instead of repeating the same pattern over and over let's define the static-inline methods in the DW PCIe header file and use them in the relevant parts of the driver. Note returning a negative error from the EP link start procedure if the start_link pointer isn't specified doesn't really make much sense since it perfectly normal to have such platform. Moreover even pci_epc_start() doesn't fail if no epc->ops->start callback is spotted. As a side-effect of this modification we can set the generic DW PCIe and Layerscape EP platform drivers free from the empty start_link callbacks and as such entirely dummy dw_pcie_ops instances.

All except the pcie_port structure which contains the DW PCIe Root Port descriptor. For historical reason the structure has retained the original name since commit 340cba6092c2 ("pci: Add PCIe driver for Samsung Exynos") when the DW PCIe IP-core support was added to the kernel. Let's finally fix that by adding the dw_ prefix to the structure name and by adding the _rp suffix to be similar to the EP counterpart. Thus the name will be coherent with the common driver naming policy. It shall make the driver code more readable eliminating visual confusion between the local and generic PCI name spaces.

Hi Serge, I think that most variable and parameters of this type is named "pp" for "pcie_port". If this is the way we want to go, those should be changed also to "rp", right? /Jesper > Signed-off-by: Serge Semin <Sergey.Semin@baikalelectronics.ru> > > --- > > Changelog v4: > - This is a new patch created on the v4 lap of the series. > --- > drivers/pci/controller/dwc/pci-dra7xx.c | 12 +++---- > drivers/pci/controller/dwc/pci-exynos.c | 6 ++-- > drivers/pci/controller/dwc/pci-imx6.c | 6 ++-- > drivers/pci/controller/dwc/pci-keystone.c | 20 +++++------ > drivers/pci/controller/dwc/pci-layerscape.c | 2 +- > drivers/pci/controller/dwc/pci-meson.c | 2 +- > drivers/pci/controller/dwc/pcie-al.c | 6 ++-- > drivers/pci/controller/dwc/pcie-armada8k.c | 4 +-- > drivers/pci/controller/dwc/pcie-artpec6.c | 4 +-- > .../pci/controller/dwc/pcie-designware-host.c | 36 +++++++++---------- > .../pci/controller/dwc/pcie-designware-plat.c | 2 +- > drivers/pci/controller/dwc/pcie-designware.h | 30 ++++++++-------- > drivers/pci/controller/dwc/pcie-dw-rockchip.c | 4 +-- > drivers/pci/controller/dwc/pcie-fu740.c | 2 +- > drivers/pci/controller/dwc/pcie-histb.c | 10 +++--- > drivers/pci/controller/dwc/pcie-intel-gw.c | 6 ++-- > drivers/pci/controller/dwc/pcie-keembay.c | 4 +-- > drivers/pci/controller/dwc/pcie-kirin.c | 2 +- > drivers/pci/controller/dwc/pcie-qcom.c | 4 +-- > drivers/pci/controller/dwc/pcie-spear13xx.c | 6 ++-- > drivers/pci/controller/dwc/pcie-tegra194.c | 22 ++++++------ > drivers/pci/controller/dwc/pcie-uniphier.c | 10 +++--- > drivers/pci/controller/dwc/pcie-visconti.c | 6 ++-- > 23 files changed, 103 insertions(+), 103 deletions(-) > > diff --git a/drivers/pci/controller/dwc/pci-dra7xx.c b/drivers/pci/controller/dwc/pci-dra7xx.c > index dfcdeb432dc8..a174b680b2a7 100644 > --- a/drivers/pci/controller/dwc/pci-dra7xx.c > +++ b/drivers/pci/controller/dwc/pci-dra7xx.c > @@ -178,7 +178,7 @@ static void dra7xx_pcie_enable_interrupts(struct dra7xx_pcie *dra7xx) > dra7xx_pcie_enable_msi_interrupts(dra7xx);

Basically you may be right, but the change you suggest is much harder to provide and may cause additional problems I have much doubts it is really required. One thing is to update the struct name, but a whole another story is to change the variables definition especially across all the platform drivers involved here and especially of such frequently used object as the DW PCIe Root Port descriptor. First of all what you suggest will affect much-much-much more code lines than this one, which in its turn will eventually cause problems with the backporting of the new patches to the older stable kernels released before the one with the updated names. Secondly it is a matter of a separate patch, which can be added by someone who would think it was really required. So to speak I don't think that changing the variable names worth it especially seeing the driver naming convention isn't perfect at all in many other aspects like using name "pci" of the dw_pcie structure instance. -Sergey > > /Jesper > > > Signed-off-by: Serge Semin <Sergey.Semin@baikalelectronics.ru> > > > > --- > > > > Changelog v4: > > - This is a new patch created on the v4 lap of the series. > > --- > > drivers/pci/controller/dwc/pci-dra7xx.c | 12 +++---- > > drivers/pci/controller/dwc/pci-exynos.c | 6 ++-- > > drivers/pci/controller/dwc/pci-imx6.c | 6 ++-- > > drivers/pci/controller/dwc/pci-keystone.c | 20 +++++------ > > drivers/pci/controller/dwc/pci-layerscape.c | 2 +- > > drivers/pci/controller/dwc/pci-meson.c | 2 +- > > drivers/pci/controller/dwc/pcie-al.c | 6 ++-- > > drivers/pci/controller/dwc/pcie-armada8k.c | 4 +-- > > drivers/pci/controller/dwc/pcie-artpec6.c | 4 +-- > > .../pci/controller/dwc/pcie-designware-host.c | 36 +++++++++---------- > > .../pci/controller/dwc/pcie-designware-plat.c | 2 +- > > drivers/pci/controller/dwc/pcie-designware.h | 30 ++++++++-------- > > drivers/pci/controller/dwc/pcie-dw-rockchip.c | 4 +-- > > drivers/pci/controller/dwc/pcie-fu740.c | 2 +- > > drivers/pci/controller/dwc/pcie-histb.c | 10 +++--- > > drivers/pci/controller/dwc/pcie-intel-gw.c | 6 ++-- > > drivers/pci/controller/dwc/pcie-keembay.c | 4 +-- > > drivers/pci/controller/dwc/pcie-kirin.c | 2 +- > > drivers/pci/controller/dwc/pcie-qcom.c | 4 +-- > > drivers/pci/controller/dwc/pcie-spear13xx.c | 6 ++-- > > drivers/pci/controller/dwc/pcie-tegra194.c | 22 ++++++------ > > drivers/pci/controller/dwc/pcie-uniphier.c | 10 +++--- > > drivers/pci/controller/dwc/pcie-visconti.c | 6 ++-- > > 23 files changed, 103 insertions(+), 103 deletions(-) > > > > diff --git a/drivers/pci/controller/dwc/pci-dra7xx.c b/drivers/pci/controller/dwc/pci-dra7xx.c > > index dfcdeb432dc8..a174b680b2a7 100644 > > --- a/drivers/pci/controller/dwc/pci-dra7xx.c > > +++ b/drivers/pci/controller/dwc/pci-dra7xx.c > > @@ -178,7 +178,7 @@ static void dra7xx_pcie_enable_interrupts(struct dra7xx_pcie *dra7xx) > > dra7xx_pcie_enable_msi_interrupts(dra7xx);
